How Lenders Calculate Affordability

UK mortgage lenders typically use income multiples of 4 to 4.5 times your annual salary. They also perform affordability assessments based on your outgoings, credit history, and ability to afford payments if interest rates rise. Higher earners may access 5x multiples.

Stamp Duty Considerations

Remember to factor in Stamp Duty Land Tax (SDLT) when budgeting. First-time buyers pay no stamp duty on the first £425,000 of properties up to £625,000. Standard buyers pay 0% up to £250,000, then increasing rates above this threshold.

Improving Your Borrowing Power

To maximise your borrowing: save a larger deposit (better rates at 10%, 15%, 20% LTV), improve your credit score, reduce existing debts, and consider a longer mortgage term. Joint applications with a partner combine both incomes.
