Interest-only mortgages: A guide for property investors & homeowners
Considering going interest only? Here’s everything you need to know.

AI summary
An interest-only mortgage allows you to pay only the interest for a set period, not the principal. This lowers short-term costs and can be useful for investors seeking tax advantages or owner-occupiers managing temporary financial difficulty.
However, the risks are significant. You will pay more interest over the life of the loan, and repayments increase substantially when the interest-only period ends. It can also be harder to get approved and carries a risk of negative equity.
