Interest only mortgages

If you repay all or part of your mortgage on an interest only basis, your monthly payments only pay the interest due and don’t go towards reducing the amount you borrowed. So it’s important you have plans in place and regularly check they’re on track to repay the full interest only amount by the end date of the mortgage.

YOUR MORTGAGE IS SECURED ON YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DON'T KEEP UP REPAYMENTS ON YOUR MORTGAGE.

Mortgages are subject to underwriting and criteria. Minimum age 18, UK residents only.
