Each example is based on a 15% deposit, 35-year term, 5-year fixed rate at 4.54%, and no existing debt. It’s designed to help you understand how lenders assess affordability, not to give personalised advice.

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:
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.
For a £250,000 property, after a 15% deposit, you’d borrow £212,500.
On a 35-year term at 4.54% fixed for 5 years, monthly repayments are approximately £1,010.94.
If all lender requirements are met and they offer 4× your income, you’d typically need a minimum salary of around £53,125.
