How much can you borrow?

Working out how much you can afford is one of the first steps when buying your first home. Lenders look at your income, deposit, and financial situation to decide how much they’re willing to lend.

For these examples, we’ve assumed:

  • You’re a first-time buyer
  • You have no existing debts
  • A 15% deposit
  • A 35-year mortgage term
  • A 5-year fixed rate of 4.54%

These scenarios are for illustration only. They’re based on standard affordability calculations, assuming a lender is prepared to offer 4× your annual salary. Actual figures will vary by lender and personal circumstances.

What salary do I need for a £250,000 mortgage in the UK?

For a £250,000 property, after a 15% deposit, you’d borrow £212,500.

Factors influencing affordability

  • Income multiples – lenders typically offer around 4× your annual salary
  • Affordability checks – monthly expenses, credit history, and deposit size matter
  • Type of income – stable, regular income gives more lending options
  • Lender criteria – each lender has their own limits and stress tests

Estimated monthly repayments

On a 35-year term at 4.54% fixed for 5 years, monthly repayments are approximately £1,010.94.

Example salary range

If all lender requirements are met and they offer 4× your income, you’d typically need a minimum salary of around £53,125.

“These examples show what lenders typically look at when deciding how much you can borrow, but they’re not a substitute for tailored advice.” - Will Sharman

“In this scenario, we’ve assumed a first-time buyer with no debts, a 15% deposit, a 35-year term, and a 5-year fixed rate of 4.54% to keep the comparisons clear.” - Will Sharman
