With an interest only mortgage, you only pay off the interest on a monthly basis throughout the term of your mortgage, however at the end of your term you are required to pay off the capital debt (the outstanding mortgage amount) in full. With a capital and interest mortgage, you pay off both the capital debt and the interest on a monthly basis.
