See a property you like? Update the price and your estimated costs while you’re there. Allow for work it may need, then explore what could be left in your budget after mortgage repayments and everyday spending.

Planning a car purchase or a change in income? Adjust your costs and compare the effect. Nestable brings your funds, costs, deposit and home estimates together, so you can explore more than a mortgage repayment alone.

Will it tell me what I can borrow?

No. Nestable provides estimates, not a lending decision. Check your borrowing options and figures with your bank or an independent mortgage adviser before committing to a home.
