Repayment and interest-only mortgages are two different types of mortgage repayment structures. Here’s an explanation of each: Repayment Mortgage: A repayment mortgage, also known as a capital and interest mortgage, is a type of mortgage where your monthly payments cover both the interest on the loan and the repayment of the principal amount borrowed. Over the term of the mortgage, typically 25 to 30 years, your monthly payments gradually reduce the outstanding balance. At the end of the term, assuming all payments have been made, the mortgage is fully repaid, and you own the property outright. Interest-Only Mortgage: An interest-only mortgage is a type of mortgage where your monthly payments only cover the interest charges on the loan. Unlike a repayment mortgage, you do not make any principal repayments during the term of the mortgage. As a result, the outstanding balance of the loan remains the same throughout the mortgage term. Therefore your monthly payments are less. However, lenders may restrict the maximum loan to value on an interest only basis – generally between 50% to 75%. With an interest-only mortgage, you are required to have a separate plan or investment vehicle in place to repay the principal amount at the end of the mortgage term for residential mortgages. This could involve savings, investments, or other arrangements that aim to accumulate sufficient funds to pay off the loan. It’s crucial to ensure that the repayment plan is robust and will be able to cover the loan amount.
