Total cost of the home

Don’t just see the monthly payment — see total interest, total repaid, and the true 30-year cost of each home you might buy.

Rate-rise stress test

See exactly what your monthly payment becomes if rates rise +1%, +2%, or +3% when your fixed period expires — before you sign.

Local property rules

Accurate stamp duty, first-time buyer schemes (Help to Buy, First Home Scheme, FHSA, KfW…), and lender limits for 52 housing markets.

How much can you borrow?

Get a quick affordability estimate before you dive into the full analysis. We apply local lender rules so the number is realistic — not a generic global ratio.

Affordability check
