Who it’s for

Buyers sizing up a self-storage deal.

For buyers working from a broker package: enter what you know, estimate the rest, and see what the facility is worth today and once it is stabilized.

What it does

  • A guided flow through property, unit mix, operations, financing, stabilization, optional expansion, and hold and exit.
  • NOI today versus stabilized, plus IRR, equity multiple, cash-on-cash, DSCR, debt yield, cap rate and yield on cost.
  • A verdict against the investment targets you set, with an IRR sensitivity table across exit cap rate and occupancy.
  • A multi-page PDF investment memo you can share with partners or lenders.
  • Works offline. No account, and your deal data stays on your device.
