How it works

From listing to verdict in three steps

  1. 1

    Paste a listing

    Drop in a Centris or Realtor.ca link, or type four numbers: price, units, average rent and city.

  2. 2

    Get the verdict

    See cash flow, DSCR, cap rate and a deal score, with expenses pre-filled from regional benchmarks you can adjust.

  3. 3

    Offer with a number

    Know the highest price that still meets your DSCR target before you write an offer.

Why PropStack

Underwriting that thinks like a Canadian lender

Everything you'd build in a spreadsheet for a 5+ unit deal, without the spreadsheet.

Canadian mortgage math

Semi-annual compounding and term renewals across the full amortization, not a US calculator with a maple leaf.

10-year projections

Cash flow, principal paydown and appreciation year by year, with overrides for rent and expenses.

Stress-test scenarios

See what a higher renewal rate or more vacancy does to cash flow before it happens.

Compare deals side by side

Line up your shortlist and see which one wins on the metrics you care about.

A deal score on your terms

Set your own targets for DSCR, cap rate and cash-on-cash. Every deal is scored against them.
