What you can do today

Screen a deal using your numbers—rent, costs, finance, timing—then see the outputs that drive the decision.

  • Price cap (Max offer)

    The highest price that still meets your target return under the current assumptions.

  • Upfront cash needed (Cash required at entry)

    Deposit + one-off costs (incl. SDLT and any fees paid in cash). Upfront refurb spend is included; phased refurb adds to peak cash instead.

  • Rent cover (ICR) check (ICR (stressed))

    Lender rule for stressed interest-only rent cover; numerator can be gross rent / net rent / NOI; illustrative only.

  • Sensitivity scenarios (Sensitivity)

    Shows how key outputs move under standardized rent, rate, and exit shocks.

How it works

Three steps to a clear decision

Step 1

Enter the deal

Start with rent, price, timing, and one-off costs to establish the baseline scenario.
Step 2

Layer financing + assumptions

Add leverage, rates, fees, and exit assumptions to see how the deal behaves.
Step 3

Read the results

Review price caps, cash requirements, lender checks, and sensitivities in plain language.
