Interest-only mortgages can be a useful financial tool for certain types of borrower, but they also come with a critical phase at the end of the term when the full repayment of the loan becomes due. In this article, we will explore what happens at the end of an interest-only mortgage, and the risks and benefits involved in managing this type of mortgage.
Understanding Interest-Only Mortgages
An interest-only mortgage allows borrowers to pay only the interest on the loan until the end of the mortgage term, which is typically 25 – 30 years’ long from the outset. This means that the monthly mortgage payments are significantly lower than they would be under a traditional repayment mortgage, as none of the principal, i.e. the original amount borrowed, is being paid off over the course of the mortgage term.
This structure can be beneficial for borrowers looking to reduce their monthly outgoings in the short term, such as investors in buy-to-let properties. However, it does mean that at the end of the interest-only period, the entire loan principal remains outstanding, creating a significant financial obligation.
