There are two main ways to pay off a mortgage which are known as "repayment" or "interest only" mortgages:
With a repayment mortgage you make monthly repayments covering both the interest and a portion of the loan over an agreed period (the term) until you've paid back both the loan and the interest
With an interest only mortgage you make monthly repayments over an agreed period that only covers the interest on your loan. However, you will still have to pay off the full loan at the end of the term.
You may also benefit from placing part of your loan as repayment and the other part as interest only. We will advise you on the best course of action.
