How much mortgage can I get on £300,000 a year?
Most UK lenders lend around 4 to 4.5 times income, so roughly £1,200,000 to £1,350,000 on a single £300,000 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 £1,350,000 at 4.5% over 25 years costs about £7,504 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.
