Use the calculator

    Open the calculator

    Open More, then Pro Calculator. From a property page, use Returns to start with that property's price and rent.

  2. 2

    Choose a mode

    Pick Sale, Rent, Land or Commercial.

  3. 3

    Pick a strategy

    For a sale, choose from the strategies below.

  4. 4

    Enter your assumptions

    Check the price, deposit, interest rate, running costs and fees. Set "Buyer status" so stamp duty is right.

  5. 5

    Stress-test it

    Raise the interest rate by one or two points and see whether the deal still works.

  6. 6

    Save the calculation

    Select "Save Calculation" and give it a name. Find it later under More, then Saved Calculations.
