What lenders will see
Standard maximum mortgage: Most UK lenders offer between 4× and 4.5× your salary — £400k to £450k on your income.
The gap: The average London home costs £525k. This is 5.3× your salary, which exceeds standard criteria. A larger deposit bridges part of the gap.
Deposit guidance: A deposit of 15–20% will strengthen your application and unlock better mortgage rates.
Local context: London
While the UK average house price is approximately £285,000, London's average of £525,000 reflects the sustained demand and constrained supply that make the capital unique. On £100,000, a 4.5× mortgage supports borrowing up to £450,000, and with a 15% deposit of around £90,000, your total budget could reach £540,000 — right at the London average. This opens up a broad choice of properties including family homes in outer boroughs and larger flats in desirable inner areas.
