A rough guide, not a mortgage offer or advice. 4 to 4.5 times is typical; 5x and above is usually limited to higher earners or specific lenders. Repayments use an illustrative 4.5% rate.

How much mortgage can I get on £100,000 a year?
Most UK lenders lend around 4 to 4.5 times income, so roughly £400,000 to £450,000 on a single £100,000 salary. Some lenders go to 5 or 5.5 times for higher earners or certain professions. Affordability checks on your outgoings and credit decide the final figure.
What would the repayments be?
Borrowing £450,000 at 4.5% over 25 years costs about £2,501 a month on a repayment basis.
Does a joint application change this?
Yes. Lenders usually apply the multiple to the combined income of all applicants, so two incomes can raise the amount you can borrow.
