How to use this glossary

This page collects the real estate investing terms you will hear on podcasts, from lenders and in offering documents, grouped roughly in the order you meet them while working through a deal. Financial measures spell out what goes in and what stays out, because many arguments about a deal's numbers are really arguments about definitions. If you are just starting, the beginner's guide to real estate investing puts these ideas in order.

Most rental analysis follows one chain:

1. Gross potential rent, minus vacancy and credit loss, plus other income, equals effective gross income.
2. Effective gross income minus operating expenses equals net operating income (NOI).
3. NOI divided by the price gives the cap rate. NOI divided by the annual loan payments gives the DSCR.
4. NOI minus debt service and reserves equals cash flow. Cash flow divided by the cash you put in gives cash-on-cash return.
5. Over the whole hold, cash flow plus sale or refinance proceeds produce the IRR and equity multiple.

Hypothetical example: the fourplex used throughout

Several definitions below use the same made-up property so you can see how the measures relate. Every figure is an assumption chosen for round numbers, not a market average or a rate quote.

Operating expenses: property taxes $7,000, insurance $3,500, property management $4,500, repairs and maintenance $3,500, owner-paid water, sewer and trash $2,500, and administrative and other costs $1,000. The loan payment works out to about $2,495 a month.

Ownership, equity and returns

Appreciation

The increase in a property's market value over time. Market appreciation comes from forces outside your control, such as rising rents, inflation, limited supply and neighborhood demand; values can also fall. Forced appreciation comes from improving the property itself (renovating, bringing rents to market, cutting waste), which works because income properties are valued largely on their NOI. Hypothetical: if an apartment building adds $3,000 a year of NOI and buyers price such buildings at a 7% cap rate, its value rises by about $42,900 ($3,000 ÷ 0.07). That link is strongest for commercial property, including apartment buildings with five or more units; lender appraisals of one- to four-unit properties lean mainly on comparable sales, so higher rents on a duplex or fourplex raise its appraised value less directly.

Equity

Your ownership stake: the property's current market value minus everything owed against it. Equity starts with your down payment and grows as you pay down the loan (scheduled or extra principal payments), as market value rises, and when improvements add at least as much value as they cost. It shrinks if values fall or you borrow more against the property. Equity is wealth on paper; you reach it only by selling or refinancing, and both cost money. At purchase, the example fourplex has $125,000 of equity ($500,000 − $375,000).

Equity = market value − all loan balances and liens

Cash flow

The money left after the property pays its operating expenses, its loan payments and whatever you set aside for capital spending. Investors usually mean annual cash flow before income taxes.

Cash flow before tax = NOI − debt service − capital expenditures or reserves

• Accounts for: rent and other income actually collected, minus every operating expense, the full loan payment (principal and interest) and capital spending or reserves.
• Excludes: depreciation (a non-cash tax deduction), income taxes and appreciation. Principal paydown builds equity, but because it is part of the loan payment it still reduces cash flow.
• Where practice varies: some investors deduct a steady reserve, others actual capital spending in the year it happens, and many listings deduct neither, which flatters the number.

Example fourplex: $35,000 − $29,939 − $1,000 = $4,061 a year, or about $338 a month across four units.

Leverage

Using borrowed money to control more property than your cash alone would buy. Leverage magnifies results in both directions, because gains and losses on the whole property land on a smaller slice of equity. It is positive when the property's unlevered yield (its cap rate) is higher than the loan constant, which is annual debt service divided by the loan amount, and negative when the debt costs more than the property yields.

The example fourplex shows negative leverage: its loan constant is about 8.0% ($29,939 ÷ $375,000) against a 7.0% cap rate (see cap rate vs cash-on-cash return). Leverage can still pay off through appreciation and principal paydown, but it raises the odds that a vacancy spike, a big repair or a higher refinance rate leaves the property unable to cover its payments.

Title and deed

Title is legal ownership: the rights to use, lease, sell and borrow against a property. A deed is the signed document that transfers title from seller to buyer; it is recorded in the county's public records. Before closing, a title company or attorney searches those records for liens, easements and ownership defects (see title insurance).

LLC (holding entity)

A limited liability company is a common way to hold rental property. It can separate a property's liabilities from your personal assets, but the protection has limits: it will not shield you from your own negligence or from a personal guarantee you signed, and mixing personal and LLC money can weaken it. Entity choice also affects what financing you can use and how the property is taxed, and formation rules and fees vary by state, so it is a question for an attorney and a tax professional. Moving a mortgaged property into an LLC can also raise a due-on-sale issue.

Income, expenses and NOI

Gross potential rent (GPR)

The rent a property would collect in a year if every unit were leased at its scheduled rent and every tenant paid in full. It is a ceiling, not a forecast. Some analyses price GPR at market rent and track the gap between market rent and actual leased rent separately as loss to lease. Example fourplex: 4 units × $1,250 × 12 = $60,000.

Vacancy rate

The share of a property's units or potential rent that is not producing income. Two versions get mixed up:

• Physical vacancy counts empty units: vacant units ÷ total units.
• Economic vacancy counts lost money: income lost to empty units, rent concessions, unpaid rent (credit loss or bad debt) and, when gross potential rent is priced at market, below-market leases (loss to lease) ÷ gross potential rent.

Economic vacancy is the more useful number for underwriting, because a building can be fully occupied and still lose income to tenants who do not pay. For context, the Census Bureau's national rental vacancy rate, a physical measure of vacant units for rent, was 7.3% in the second quarter of 2026. National figures are a backdrop, not an input: underwrite a specific property with local data and its own rent history. The example fourplex assumes 5% vacancy and credit loss, or $3,000.

Effective gross income (EGI)

The income you realistically expect to collect: gross potential rent, minus vacancy and credit loss, plus other income such as laundry, parking, storage, pet fees and utility reimbursements.

EGI = gross potential rent − vacancy and credit loss + other income

Example fourplex: $60,000 − $3,000 + $0 = $57,000.

Operating expenses

The recurring costs of running a property.

• Includes: property taxes, insurance, property management, repairs and maintenance, owner-paid utilities, on-site payroll, landscaping and snow removal, turnover cleaning, administrative, legal and accounting costs, marketing and leasing, and HOA or association dues.
• Excludes: loan principal and interest, depreciation, income taxes, capital expenditures, and the owner's personal expenses.

Two common traps in seller statements: no management fee (budget one even if you self-manage, because lenders and future buyers will typically assume one), and a property tax bill that may be reassessed upward after the sale. The example fourplex's $22,000 of operating expenses equals about 39% of its effective gross income.

Net operating income (NOI)

What the real estate itself earns: income after operating expenses but before financing and income taxes. Because NOI ignores who owns the property and how it was financed, it is the number behind commercial property values (through the cap rate) and loan sizing (through DSCR).

NOI = effective gross income − operating expenses

• Includes: all rental and other operating income, net of vacancy and credit loss, and all operating expenses.
• Excludes: debt service (principal and interest), depreciation and other non-cash write-offs (such as amortized loan costs), income taxes and capital expenditures.
• Where practice varies, vacancy: a trailing NOI reflects the vacancy and unpaid rent that actually occurred, while a projected NOI deducts an allowance, and some marketing packages assume almost none. Lenders set their own floor: Fannie Mae's multifamily guide, for example, underwrites vacancy, concessions and bad debt at no less than 5% of gross potential rent, even for a full building.
• Where practice varies, reserves: some appraisers and lenders deduct an annual replacement reserve before NOI. Others keep NOI before reserves and call the after-reserve figure net cash flow (NCF); the same Fannie Mae guide subtracts a replacement reserve from underwritten NOI to reach underwritten NCF. Many listings leave reserves out entirely.

Before you compare two NOI figures, or the cap rates built on them, check how each treats vacancy and reserves. Example fourplex: $57,000 − $22,000 = $35,000 of NOI before reserves, or $34,000 after the $1,000 reserve. For ways operators grow NOI on the expense side, see how multifamily owners increase NOI without raising rent.

Capital expenditures (CapEx)

Spending that replaces a major component, extends a property's life or adds value: roofs, HVAC systems, water heaters, windows, parking lots and unit renovations. Because these costs are large and irregular, they sit outside operating expenses (and usually outside NOI), but they still come out of your cash flow. A repair keeps the property in ordinary working condition; a capital expenditure replaces or upgrades. The IRS draws a similar line for taxes: costs that result in a betterment, restore the property or adapt it to a new use must be capitalized and depreciated rather than deducted all at once (IRS Publication 527).

Replacement reserves

Money set aside each year for future capital expenditures, usually budgeted per unit per year. Some lenders require reserves to be paid into an escrow account; a June 2026 term sheet for Fannie Mae's small multifamily loans, for example, says replacement reserve, tax and insurance escrows are typically required on higher-leverage loans (Lument). The example fourplex budgets $250 per unit per year; an older building with aging systems may need far more.

Rent roll

A list of every unit with its tenant, lease start and end dates, current rent, deposit and any balance owed. A rent roll is the seller's claim about who pays what. Check it against the actual leases and bank deposits during due diligence.

T-12 (trailing 12 months)

The property's income and expense statement for the most recent 12 months. It shows actual operating history, including seasonal swings, and is the usual starting point for underwriting. In episode 695, Jason Williams, founder of Ironclad Underwriting, describes how his underwriting web app cross-references offering memorandums, T12 financials and rent rolls to flag discrepancies so investors do not overpay.

Pro forma

A projection of a property's future income and expenses, usually after planned changes such as renovations or rent increases. The offering memorandum (OM), the marketing package for a property or investment, typically includes one. A seller's or sponsor's pro forma is built on their assumptions: compare every line with the T-12 and ask what has to go right for the projection to happen.

Triple-net lease (NNN)

A commercial lease in which the tenant pays rent plus its share of the property's three main operating costs: property taxes, insurance and maintenance, often including common area maintenance (CAM). Because the tenant carries most expenses, the landlord's NOI tends to be steadier, but the investment depends heavily on the tenant's credit and the remaining lease term. Terms vary; some leases labeled NNN leave the roof and structure with the landlord, so read the lease rather than the label. In a gross lease the landlord pays operating costs out of a higher rent, and a modified gross lease splits them. Net leases are common in single-tenant retail and industrial property.

Deal analysis metrics

Underwriting

Checking a deal's numbers and risks before you commit money: verifying income and expenses against the T-12, rent roll and leases, budgeting repairs and reserves, sizing the financing and stress-testing the assumptions (what happens if vacancy rises, rents stall or the exit cap rate is higher). Lenders underwrite both the borrower and the property; investors underwrite the deal, using the seller's or sponsor's numbers as a starting point, not a substitute.

Capitalization rate (cap rate)

A property's NOI as a percentage of its price or value: roughly the unlevered, first-year yield an all-cash buyer would earn, before closing costs and (usually) reserves. Commercial buyers use it to compare prices across properties.

Cap rate = NOI ÷ purchase price (or current value)

• Inputs: NOI and price. Because it uses NOI, it ignores financing, depreciation and income taxes, so at a given price and NOI it is the same for every buyer, however they finance it.
• Limits: it is a one-year snapshot that ignores rent growth, capital needs and the eventual sale.
• Which NOI? A trailing cap rate uses the T-12, a going-in cap rate uses expected first-year NOI, and a pro forma cap rate uses projected NOI after improvements. An exit cap rate is the one assumed when projecting a future sale price; assuming an exit cap below today's cap rate inflates projected returns.

Rearranged, value = NOI ÷ cap rate: the basis of the income approach appraisers use for commercial property, and of forced appreciation. Example fourplex: $35,000 ÷ $500,000 = 7.0%. A lower cap rate means a higher price per dollar of income. There is no universally good cap rate; it depends on property type, location, condition, interest rates and expected growth.

Cash-on-cash return

Annual pre-tax cash flow divided by the total cash you invested: a levered, usually first-year, cash yield.

Cash-on-cash return = annual cash flow before tax ÷ total cash invested

• Numerator: NOI minus debt service minus reserves or capital spending (be consistent from deal to deal).
• Denominator: down payment, closing costs, loan fees and any upfront repairs or reserves you funded. Not the purchase price.
• Excludes: appreciation, principal paydown and tax benefits, which is why it understates the total return on properties bought mainly for growth.

Example fourplex: $4,061 ÷ $135,000 = 3.0%.

Gross rent multiplier (GRM)

Price divided by gross annual rent: a quick screen for comparing similar properties in the same market. It ignores expenses, vacancy and financing, so two buildings with the same GRM can have very different NOI.

GRM = price ÷ gross annual rent

Example fourplex: $500,000 ÷ $60,000 = 8.3. Appraisals of two- to four-unit properties traditionally use monthly rent instead (the long-standing Fannie Mae Form 1025 / Freddie Mac Form 72 appraisal report multiplies gross monthly rent by the GRM), which gives a number 12 times larger: 100 for the fourplex ($500,000 ÷ $5,000). Check which convention a figure uses.

Return on investment (ROI)

A generic label rather than one formula. One person's ROI is annual cash flow divided by cash invested (cash-on-cash return); another's is total profit over the hold including appreciation; another's adds tax savings. When someone quotes an ROI, ask what is in the numerator, what is in the denominator and over what period.

Rules of thumb: the 1% rule and the 50% rule

The 1% rule says monthly rent should be at least 1% of the purchase price (plus any upfront repairs). The 50% rule says operating expenses, vacancy and capital costs will run about half of gross rent over time, not counting the mortgage. Both are quick screens for small residential rentals, not underwriting. The example fourplex meets the 1% rule exactly ($5,000 ÷ $500,000), yet its first-year cash-on-cash return is only about 3%, and the 50% rule would leave it $30,000 before the mortgage, barely enough to cover $29,939 of debt service. A screen does not know your financing, your tax bill or the age of the roof.

Break-even occupancy

The share of potential rent you must collect to cover operating expenses and debt service. The lower it is, the more cushion you have.

Break-even occupancy = (operating expenses + debt service) ÷ gross potential rent

Example fourplex: ($22,000 + $29,939) ÷ $60,000 = 86.6%, so collections can fall about 13% short of potential rent before NOI stops covering the mortgage, assuming expenses stay the same. Counting the $1,000 reserve raises the break-even to 88.2%.

After-repair value (ARV)

The estimated market value of a property once planned renovations are finished, based on recent sales of comparable renovated properties. Flippers, BRRRR investors and rehab lenders build their numbers on it, so an optimistic ARV can sink a deal even when everything else goes to plan. A widely repeated flipping shortcut, the "70% rule", caps the purchase price at (ARV × 70%) − repair costs; like other rules of thumb, it ignores your actual financing, holding time and local selling costs.

Comparable sales (comps)

Recent sales of similar properties nearby, adjusted for differences in size, condition, features and sale date. Comps support as-is value and ARV for houses and small multifamily properties, and lenders rely on a licensed appraiser's comps rather than yours. For larger income properties, appraisers also lean on the income approach (NOI ÷ market cap rate), so "comps" may mean comparable cap rates and prices per unit. Use closed sales, not list prices.

Internal rate of return (IRR)

The annualized return that accounts for when each dollar goes in and comes out over the whole hold. Technically, it is the discount rate at which the present value of all cash flows (your investment as a negative number, then distributions and sale proceeds) nets to zero. In a spreadsheet, use IRR for cash flows at even intervals (it returns the rate per period, so convert a monthly result to an annual rate) or XIRR with actual dates.

• Inputs: the amount and timing of every contribution and distribution, including the sale or refinance.
• Limits: it is sensitive to timing and to the assumed sale price (and exit cap rate), it says nothing about total profit, and a projected IRR is a forecast, not a result. Ask whether a quoted IRR is levered or unlevered and net or gross of sponsor fees.

Equity multiple

Total cash distributions over the life of an investment divided by total cash invested. A 2.0x multiple means you got back twice what you put in: your capital plus an equal amount of profit. It ignores time, so 2.0x over four years and 2.0x over twelve years look identical. That is why it is usually read alongside IRR (see the comparison below).

Equity multiple = total distributions ÷ total equity invested

Financing and debt

Loan-to-value (LTV)

The loan amount compared with the property's value. Lenders use it to decide whether to lend, how much and at what rate, and a bigger down payment means a lower LTV (CFPB).

LTV = loan amount ÷ property value

On a purchase, lenders generally use the lower of the price and the appraised value, and on a refinance the appraised value (Fannie Mae Selling Guide), so paying more than the appraisal does not raise the loan you can get. Example fourplex: $375,000 ÷ $500,000 = 75%. Maximums vary by lender and loan type; a June 2026 lender term sheet for Fannie Mae's small multifamily loans (five or more units) lists an 80% maximum LTV and a 1.25x minimum DSCR. Combined LTV (CLTV) adds any second loans against the same property.

Loan-to-cost (LTC)

The loan amount divided by the total project cost: the purchase price plus the renovation or construction budget, and sometimes closing and carrying costs. Lenders use it on rehab, construction and bridge loans, where today's value is the wrong yardstick because the property is about to change. See LTV vs LTC for an example.

LTC = loan amount ÷ total project cost

Debt service coverage ratio (DSCR)

How many times a property's NOI covers its annual loan payments.

DSCR = NOI ÷ annual debt service

• Debt service is principal plus interest, or interest only during an interest-only period.
• Above 1.0x, the property covers its loan payments; below 1.0x, someone has to add cash.
• Lenders set minimums and use them to size loans; the Fannie Mae small-loan term sheet cited under LTV lists a 1.25x minimum.
• Which NOI? The lender's, not the seller's: lenders apply their own vacancy and expense assumptions, and some deduct a replacement reserve first. Fannie Mae's multifamily guide, for example, divides underwritten net cash flow (NOI minus a replacement reserve) by debt service.

Example fourplex: $35,000 ÷ $29,939 = 1.17x, or 1.14x after the $1,000 reserve ($34,000 ÷ $29,939). A lender requiring 1.25x on $35,000 of NOI would cap annual debt service at $28,000, which supports a loan of about $350,700 at the same 7% rate and 30-year amortization, not $375,000. Commercial lenders may also check debt yield (NOI ÷ loan amount; 9.3% for the fourplex), which does not change with the interest rate or amortization.

DSCR loan

An investment-property loan, usually for one- to four-unit rentals, that qualifies mainly on the property's rental income rather than your personal income. Despite the name, some of these lenders do not use the NOI formula above: one lender's published calculator divides expected monthly rent by PITIA (Lower). Measured that way, the example fourplex scores 1.48x ($5,000 ÷ about $3,370 of monthly PITIA) against 1.17x on NOI, because rent ÷ PITIA ignores vacancy, management, repairs and other expenses. Guidelines vary by lender. In episode 650, investor Clint Snuggs explains how refinancing with DSCR loans let him recycle capital as he grew a rental portfolio; the conversation also covers why these lenders qualify the loan on what the property brings in rather than on the borrower's W-2 income.

Amortization

Paying off a loan through scheduled payments that cover interest and gradually reduce principal. Early payments are mostly interest; later ones are mostly principal. The amortization period (for example, 30 years) sets the payment size and can be longer than the loan's term, which is how balloon loans arise. Example fourplex: after five years of payments, the $375,000 balance would be about $352,993, so principal paydown totals about $22,007.

Interest-only (IO)

A period in which payments cover only interest, so the balance does not shrink. Interest-only payments raise cash flow and DSCR in the short run, but they build no equity through paydown and leave the full balance due at refinance or sale. They are common on bridge loans and in syndication business plans.

Bridge loan

A short-term loan, often interest-only, that carries a property until it can qualify for long-term financing or be sold. Investors use bridge loans on value-add and transitional properties that permanent lenders will not yet finance, such as a half-empty building in the middle of a renovation. The risk is timing: if the renovation or lease-up runs late, or rates rise, the loan can come due before the property is ready to refinance.

Balloon payment

A large, one-time payment at the end of a loan's term (CFPB). It happens when the loan is not fully amortized by maturity, for example a 10-year term on a 30-year amortization schedule. Balloons are common in commercial, seller-financed and hard money loans. If rates are higher or the property is worth less when the balloon comes due, refinancing can be expensive or impossible, so plan the exit before you sign.

PITI

Principal, interest, taxes and insurance: the full monthly payment on a mortgaged property. PITIA adds association (HOA) dues. Lenders often collect the taxes and insurance through an escrow account. PITI is not the cost of owning a rental; it leaves out vacancy, repairs, management, utilities and capital expenditures. Example fourplex: about $2,495 of principal and interest plus $583 of taxes and $292 of insurance, or about $3,370 a month.

Hard money loan

A short-term loan from a private lending company, secured by the property and underwritten mainly on the deal (purchase price, rehab budget and after-repair value) rather than on your income. Investors use hard money for flips, BRRRR purchases and properties a bank will not finance in their current condition. Expect higher interest rates and upfront points than bank loans, terms measured in months rather than decades, and loan amounts set as a percentage of cost and capped by ARV. Private money usually means a loan from an individual, on terms you negotiate directly.

Points

Upfront loan fees stated as a percentage of the loan amount: one point is 1% of the loan, so 2 points on the example fourplex's $375,000 loan would be $7,500. Discount points buy a lower interest rate, but some lenders use "points" for any upfront fee calculated as a percentage of the loan, whether or not it lowers the rate (CFPB). Count them in your closing costs and cash invested.

Seller financing

The seller acts as the lender: instead of receiving all cash at closing, the seller accepts a down payment and a promissory note secured by the property, often with a balloon after a set number of years. It can work when bank financing is hard to get or a seller wants installment income, but the seller takes on a lender's risk, the due-on-sale clause in any existing mortgage can complicate it, and federal lending rules can apply when the buyer will live in the home (Regulation Z §1026.36 sets the conditions under which such sellers are exempt from loan-originator rules). Have a real estate attorney draft the documents. More on these structures: creative financing.

Due-on-sale clause and subject-to

A due-on-sale clause lets the lender, at its option, demand full repayment if the property, or an interest in it, is sold or transferred without the lender's written consent (12 U.S.C. §1701j-3). It is the central risk in subject-to deals, where a buyer takes title while the seller's existing mortgage stays in place: the lender can call the loan due. The same law bars lenders from enforcing the clause on certain transfers of one- to four-unit homes, such as to a spouse or into a living trust in which the borrower remains a beneficiary, but its implementing regulation (12 CFR 191.5) limits those protections to a home the borrower occupies or will occupy. They generally do not cover a rental you do not live in, and a transfer to an LLC is not on the list at all, so talk to the lender before deeding a mortgaged rental into a trust or an LLC.

Cash-out refinance

Replacing a loan with a larger one and taking the difference in cash. It is how BRRRR investors pull capital back out after a renovation. Lenders apply seasoning rules: under Fannie Mae's Selling Guide, at least one borrower must generally have been on title for six months, and an existing first mortgage being paid off must be at least 12 months old, with a separate delayed-financing exception for properties bought without a mortgage. Other lenders set their own rules. The cash is borrowed, not earned: it raises your payment and lowers your equity.

Recourse and non-recourse loans

With a recourse loan, the lender can pursue the borrower's or guarantor's other assets if a foreclosure sale does not repay the debt, usually through a personal guarantee. With a non-recourse loan, the lender is generally limited to the property, subject to carve-outs (sometimes called bad-boy carve-outs) that restore personal liability for acts such as fraud or bankruptcy; the Fannie Mae small-loan term sheet describes exactly that structure. Smaller investor loans are often recourse, so read the guarantee before you sign it.

Promissory note, mortgage and deed of trust

The promissory note is the borrower's written promise to repay: the debt itself. The mortgage or deed of trust is the security instrument that pledges the property as collateral and is recorded in the public records. Which one is used depends on the state; a deed of trust involves a third-party trustee and in many states allows foreclosure without a court case. When note investors buy a loan, they buy the note together with the security instrument behind it; see how note investing works.

Lien priority

The order in which claims against a property are paid from a sale or foreclosure. Generally, liens rank by the date they were recorded ("first in time, first in right"), so the first mortgage is the senior lien and a later second mortgage is junior. State law can place some liens, such as property tax liens, ahead of earlier mortgages, and a lender can agree to move behind another lien through a subordination agreement. Position matters because if a property is sold to pay its debts, the junior loan is paid only after the senior one (CFPB), and a junior lender can be left with little or nothing, which is why note buyers and private lenders care about the position they hold.

Foreclosure, REO and short sale

Foreclosure is the legal process a lender uses to repay a defaulted loan from the sale of the property. Depending on the state, it goes through the courts (judicial foreclosure) or follows required notices under a power-of-sale clause in the mortgage or deed of trust without a court case (non-judicial foreclosure), usually ending in a public auction (CFPB). If nobody outbids the lender at that sale, the lender takes the property and it becomes REO (real estate owned). A short sale is a sale for less than the amount owed on the mortgage, which the lender or servicer must agree to (CFPB). Each stage carries different risks for a buyer; see distressed real estate investing.

Buying, selling and closing

Letter of intent (LOI) and purchase agreement

A letter of intent is a short, usually non-binding outline of the price and key terms (deposit, due diligence period, financing, closing date) that the parties agree on before drafting a full contract. It is common in commercial deals. The purchase and sale agreement (PSA), or purchase contract, is the binding contract that follows, and its deadlines and contingencies are what actually protect you. Some LOI provisions, such as confidentiality or exclusivity, may be written to be binding, so read it before you sign.

Due diligence

The investigation between signing a purchase contract and committing to close. It covers the income (leases, rent roll, T-12, bank deposits), the physical condition (inspections of the roof, structure, HVAC, plumbing and sewer), the legal status (title, survey, zoning, permits and, for commercial property, environmental reports) and your own numbers (insurance quotes, the property tax bill after the sale, financing). The contract's due diligence or inspection period sets how long you have and whether you can walk away with your deposit.

Earnest money

A good-faith deposit the buyer makes when the purchase contract is signed, usually held by a title company, escrow agent or attorney and credited toward the price at closing. Whether you get it back if the deal falls apart depends on the contract: backing out under a valid contingency usually returns it, while walking away without one can mean forfeiting it.

Contingency

A condition in the contract that must be satisfied before the buyer is obligated to close. Common contingencies cover inspection, financing, appraisal and title review; commercial contracts often add review of leases and financial records. Contingencies protect the buyer, which is why sellers in competitive markets push to shorten or remove them.

Appraisal

A licensed or certified appraiser's opinion of a property's market value, usually ordered by the lender before it makes a loan. Appraisers weigh comparable sales, an income approach for rental property and sometimes a cost approach; Fannie Mae, for example, requires an income approach based on a gross rent multiplier for two- to four-unit properties but does not accept appraisals that rely on it alone. If the appraisal comes in below the contract price, lenders generally base the loan on the lower figure (see LTV), and an appraisal contingency can let you renegotiate or walk away.

Title insurance

Insurance against losses from ownership claims that arose before you bought, such as a previous owner's unpaid taxes or a contractor who says they were never paid (CFPB). A lender's policy protects the amount the lender lent and is typically required. An owner's policy protects your own investment and is your choice to buy. You can usually shop for a title insurer separately from your mortgage.

Closing costs

The fees and charges paid to complete a purchase or loan: lender fees and points, appraisal, title search and insurance, settlement or escrow fees, recording fees, transfer taxes where they apply, and prepaid items such as insurance, interest and tax escrows. Count them in your cash invested when you calculate cash-on-cash return; the example fourplex assumes $10,000.

Escrow

Two different things share the name. During a purchase, escrow is a neutral third party holding money and documents until every condition of the sale is met. After closing, an escrow account (an impound account in some places) is set up by your mortgage lender to pay property taxes and homeowners insurance out of part of your monthly payment (CFPB).

Strategy terms

Buy and hold

Buying property to rent out for years, earning cash flow while the loan amortizes and, if the market cooperates, the property appreciates. Most of the rental metrics in this glossary come from this approach.

House hacking

Living in part of a property and renting out the rest (the other units of a duplex, triplex or fourplex, a basement apartment, or spare bedrooms) so tenants cover some or all of your housing cost. Because you live there, you may qualify for owner-occupant financing, which often requires a smaller down payment than an investment-property loan: FHA-insured loans, for example, are available on one- to four-unit properties with as little as 3.5% down (HUD). Lenders impose occupancy requirements, and you become a live-in landlord. In episode 555, Michael Hoang describes buying a large house in an older neighborhood and renting rooms to young professionals, which let him and his wife live essentially for free for four years while they built their portfolio.

BRRRR

Buy, rehab, rent, refinance, repeat. You buy a property below its potential value, renovate it, lease it up, then use a cash-out refinance based on the new appraised value to recover some or all of your cash for the next deal. It depends on an accurate ARV, a rehab that stays on budget, rents that support the new loan, and a lender willing to refinance on the new value within your timeline. The refinance leaves a bigger loan behind, so cash flow afterward is often thin. More: single-family rentals and BRRRR.

Fix and flip

Buying a property, renovating it and selling it, usually within months.

Flip profit = sale price − purchase price − rehab − financing and holding costs − buying and selling costs

Holding costs (interest, taxes, insurance, utilities) and selling costs (commissions and closing costs) are easy to underestimate, and every extra month of renovation adds to them.

Wholesaling

Putting a property under contract with a seller and assigning that contract to another buyer for a fee, or closing and immediately reselling (a "double close"), without renovating. State rules on assigning contracts and marketing property you do not own vary, so check them before you start. The full picture is in real estate wholesaling: the complete guide.

Value-add

Buying a property with a fixable problem, such as dated units, below-market rents, high expenses or weak management, and improving it to raise NOI and therefore value (forced appreciation). Many apartment syndications describe their business plans this way. The risk is execution: renovation budgets, lease-up timing and the rents tenants will actually pay.

Class A, B and C properties

Informal labels for a building's quality, age and location. Class A usually means newer, well-located buildings with top-of-market rents; Class B, older but well-kept properties; Class C, older buildings with dated systems, often in less sought-after areas, with lower rents and more turnover. There is no official standard, so two brokers can grade the same building differently; ask what the label is based on. Value-add plans often aim to move a property up a class.

Passive investments and deal structures

For how these investments compare with owning property yourself, including time, fees, liquidity and taxes, see active vs passive real estate investing.

Syndication

A group investment in which a sponsor pools money from several investors to buy a property or portfolio, usually through an LLC or limited partnership. Interests in a syndication are generally securities, so the offering must be registered with the SEC or qualify for an exemption, most commonly Rule 506(b) or 506(c) of Regulation D.

General partner (GP)

The sponsor or operator who finds the deal, arranges the loan, raises the equity, carries out the business plan and makes the decisions. GPs typically earn fees plus a share of profits beyond their own invested capital (the promote). In LLC structures they are often called managers or managing members.

Limited partner (LP)

A passive investor who contributes capital to a syndication or fund, has little say in day-to-day decisions and generally risks no more than the amount invested, subject to the operating agreement. LP interests are usually illiquid until the property is sold or refinanced, so plan on your money being tied up for the full projected hold, and possibly longer.

Accredited investor

An investor who meets SEC tests that allow participation in many private offerings. For individuals, the SEC's criteria include:

• income over $200,000 (or $300,000 with a spouse or partner) in each of the prior two years, with a reasonable expectation of the same this year; or
• net worth over $1 million, alone or with a spouse or partner, excluding the primary residence; or
• holding a Series 7, Series 65 or Series 82 license in good standing.

Certain insiders, knowledgeable employees of private funds and entities (for example, those with more than $5 million in assets) can also qualify.

Regulation D: Rule 506(b) and 506(c)

The two exemptions most private real estate offerings use. Under Rule 506(b), the sponsor cannot use general solicitation or advertising and may accept unlimited accredited investors plus up to 35 non-accredited investors in any 90-calendar-day period, each of whom, alone or with a purchaser representative, must have enough financial knowledge and experience to evaluate the investment and must receive detailed disclosure. Under Rule 506(c), the sponsor can advertise publicly, but every purchaser must be accredited and the sponsor must take reasonable steps to verify it. In both cases the securities are restricted and hard to resell, and the issuer files a Form D notice.

Preferred return (pref)

A priority on distributions: limited partners receive a set annual return on their unreturned capital, such as 8%, before the sponsor shares in profits. It is not a guaranteed or fixed return; it is paid only if the property produces enough cash. The operating agreement says which kind applies:

• Cumulative: unpaid pref accrues and must be paid before the sponsor shares in profits.
• Non-cumulative: a shortfall in one year is simply lost.
• Compounding: unpaid pref itself earns pref.

Hypothetical: you invest $100,000 with an 8% cumulative, non-compounding pref, so each year the first $8,000 distributed on your stake goes to you before the sponsor shares in profits. In year one the deal distributes only $5,000 to you, leaving $3,000 accrued. In year two it distributes $11,000 to you, covering that year's $8,000 plus the $3,000 shortfall. If the property never produces enough cash, the accrued pref may never be paid.

Waterfall

The distribution order in the operating agreement that decides who receives what, and when. A simple waterfall pays (1) the preferred return, (2) return of LP capital, (3) sometimes a catch-up that sends most or all of the next dollars to the GP until it reaches its agreed share of profits, and (4) the remaining profits split between LPs and GP, for example 70/30. Some agreements return capital before paying accrued pref, which changes how refinance proceeds and other distributions before a sale are applied, so check which order yours uses. The GP's share beyond its own capital is called the promote or carried interest. Many deals add hurdles that raise the GP's share once LPs reach a target IRR or multiple.

Assumptions: LPs invest $1,000,000; the GP invests no capital; the pref is 8% cumulative and non-compounding; nothing is distributed until a sale in year five that leaves $1,700,000 for investors; there is no catch-up. The LPs' equity multiple is 1.61x. A catch-up tier or higher GP split would shift more of the $300,000 to the GP.

Capital stack

The layers of money that fund a property, from first paid to last: senior debt (the first mortgage), mezzanine debt or second liens, preferred equity, and common equity, where LPs and GPs usually sit. Each layer is paid only after the layers ahead of it, so common equity absorbs losses first and keeps the most upside. When a deal pitch mentions preferred equity, ask where your money sits in that order.

Capital call

A request from the sponsor for more money from existing investors, typically to cover a cash shortfall, unexpected repairs or a refinance gap. Read whether contributions are optional and what happens if you do not fund; some agreements dilute investors who decline. A capital call is not automatically a sign of failure, but it does mean the plan needed more cash than was raised.

Sponsor fees

Fees the GP earns in addition to its profit share, disclosed in the private placement memorandum (PPM) and operating agreement. They can include acquisition, asset management, construction management, refinance and disposition fees, plus property management fees if an affiliate manages the property. Most fees are paid before LP distributions (some agreements defer or subordinate them), so compare offerings on projections net of fees.

Real estate investment trust (REIT)

A company that owns, and typically operates, income-producing real estate or related assets such as mortgages, letting individuals share in that income without buying property themselves. REITs have to distribute at least 90% of their taxable income each year (SEC investor bulletin). Their dividends are generally taxed as ordinary income rather than at the lower rates on other corporate dividends (Investor.gov), although eligible individuals can deduct 20% of qualified REIT dividends, subject to a taxable-income limit, under the qualified business income (section 199A) deduction.

• Publicly traded REITs are listed on a stock exchange and bought and sold through a broker like other stocks.
• Non-traded REITs are registered with the SEC but not listed, which makes them illiquid and hard to value, and they generally carry high upfront fees. SEC investor materials have put sales commissions and other upfront costs at 10% to 15% of the investment (a 2016 bulletin) and at about 9% to 10% (the undated Investor.gov REIT page linked above). Neither is a current fee survey, so treat them as dated benchmarks and check the fee table in the specific offering's prospectus.
• Private REITs are unlisted private placements that do not file regular reports with the SEC and are typically limited to accredited investors.

Tax terms

These definitions are deliberately brief. For how they work together, see the tax benefits of real estate investing.

Depreciation

An annual tax deduction for the wear and tear of a building and its improvements, taken even while the property may be rising in value. Land cannot be depreciated. Under the IRS's general system, residential rental buildings are depreciated on a straight line over 27.5 years and nonresidential buildings over 39 years (Publication 527; Publication 946). Hypothetical: if $400,000 of the example fourplex's $500,000 price is allocated to the building and $100,000 to land (ignoring closing costs, some of which would be added to basis), depreciation is about $14,545 a year ($400,000 ÷ 27.5), less in the first year because of the mid-month convention. Depreciation is a non-cash expense: it reduces taxable income but is not part of NOI or cash flow.

Cost segregation

A study that splits a building's cost into components with shorter recovery periods, such as equipment, fixtures and certain land improvements, so more depreciation is taken sooner; those components can also qualify for bonus depreciation. The IRS's audit techniques guide for examiners reviewing these studies notes that personal property generally has a shorter recovery period (for example, 5 or 7 years) than the building. The trade-off comes at sale, when faster deductions on these components are generally recaptured as ordinary income (see depreciation recapture).

Bonus depreciation

An extra first-year deduction, which the IRS calls the special depreciation allowance, for qualified property: generally tangible property with a recovery period of 20 years or less, which rules out the building itself (Publication 946). The 2025 tax law made it a permanent 100% for eligible property acquired and placed in service after January 19, 2025 (IRS, Notice 2026-11), which is why it often comes up alongside cost segregation.

Depreciation recapture

Tax due on past depreciation when you sell. For real property, the IRS taxes the portion of gain called unrecaptured section 1250 gain at a maximum rate of 25% (IRS Topic 409). Depreciation on components reclassified as personal property (section 1245 property), for example through cost segregation, is generally recaptured as ordinary income instead (IRS Publication 544). So depreciation often defers tax rather than eliminating it, though it can still come out ahead if it offset income taxed at higher rates, and a 1031 exchange can push the bill further out.

1031 exchange

A way to defer tax on the gain from selling investment or business real estate by exchanging it for other like-kind real property. Key rules from the IRS instructions for Form 8824:

• Since 2018, only real property held for use in a trade or business or for investment qualifies; property held primarily for sale, such as a flip, does not.
• In a deferred exchange, you must identify replacement property within 45 days of transferring the old one and receive it within 180 days or by your tax return's due date (including extensions), whichever comes first.
• Cash, other property or net relief from mortgage debt you receive, often called boot, is taxable up to the amount of your gain.
• A qualified intermediary, which cannot be your agent or a related party, usually holds the proceeds.

Schedule K-1

The form a partnership uses to report each partner's share of its income, deductions and credits. A partnership does not pay income tax itself; it passes profits and losses through to its partners (IRS). Syndications organized as LLCs or limited partnerships are usually taxed as partnerships, so LPs receive a K-1 rather than a 1099.

Commonly confused pairs

Cap rate vs cash-on-cash return

Cap rate measures the property: NOI ÷ price, ignoring debt, the same for every buyer at that price. Cash-on-cash measures your deal: cash flow after the loan payments ÷ the cash you put in. The example fourplex has a 7.0% cap rate but a 3.0% cash-on-cash return, because its loan costs more (an 8.0% loan constant) than the property yields. Bought for cash, it would return about 6.7% after the reserve ($34,000 ÷ $510,000, assuming the same $10,000 of closing costs), so here the loan lowers the first-year cash yield. With cheaper debt, cash-on-cash can exceed the cap rate; that is positive leverage.

NOI vs cash flow

NOI is before loan payments and capital spending; cash flow is after. The example fourplex shows $35,000 of NOI but only $4,061 of cash flow. Listings advertise NOI because it describes the property; your bank account receives cash flow.

LTV vs LTC

LTV compares the loan with what the property is worth; LTC compares it with what the project costs. Hypothetical rehab: purchase price $400,000, renovation $100,000, total cost $500,000, and a $400,000 loan. That is 80% loan-to-cost. If the after-repair value is $600,000, the same loan is about 66.7% of ARV. Rehab lenders often cap both. A comfortable LTV on a projected ARV is not real equity until the work is finished and the value is proven.

IRR vs equity multiple

Equity multiple tells you how much; IRR tells you how fast. Three hypothetical $100,000 investments:

A and B return the same $60,000 profit, but B takes longer, so its IRR is lower. C has the highest IRR but the smallest profit, and you would need to find somewhere to reinvest the money after one year. Read the two measures together, and remember that projected figures depend on the sponsor's assumptions.

Preferred return vs guaranteed return

A preferred return is a place in line, not a promise: it decides who is paid first from whatever cash the property produces, and if the property produces less, the pref goes unpaid or accrues. A guaranteed return would mean someone promises to pay regardless of performance. The SEC's investor education site notes that every investment carries some degree of risk, lists high returns with little or no risk among the red flags of Ponzi schemes and advises being highly suspicious of any "guaranteed" investment opportunity.

Appreciation vs equity

Appreciation is one source of equity, not a synonym for it. Hypothetical: if the example fourplex's value grows 3% a year for five years, it would be worth $579,637, an increase of $79,637. Meanwhile the loan balance falls to $352,993. Equity grows from $125,000 to $226,644: the original down payment, plus $79,637 of appreciation, plus $22,007 of principal paydown. Borrowing against the property would reduce equity without changing appreciation.

Other pairs that trip people up

• Physical vs economic vacancy: empty units vs lost income (see vacancy rate).
• DSCR on a commercial loan vs a residential DSCR loan: NOI ÷ debt service vs, at some lenders, rent ÷ PITIA. The fourplex scores 1.17x one way and 1.48x the other.
• NOI vs net cash flow (NCF): NCF is NOI after a replacement reserve, and some lenders size loans on it (see NOI).
• Repair vs capital improvement: a repair is generally deductible; an improvement is capitalized and depreciated (see CapEx).
• Passive investing vs a passive activity: the first describes your role; the second is an IRS category with loss-limitation rules. Rental activities are generally passive under those rules even if you are hands-on, with exceptions such as qualifying as a real estate professional (IRS Topic 425).
