Guide to Interest Only Mortgages UK

These are mortgages where for a fixed time of 25 years you only pay the interest payments on the mortgages. Usually with a mortgage you pay both the interest on the loan plus an amount to reduce the capital.

With an interest only mortgage it means that you need a separate plan to save money so that you can repay the capital on the mortgage at the end of your 25 year period.

The main problem with interest only mortgages is that there is no guarantee that you will be able to pay off the mortgage at the end of your mortgage period.

Advantages of Interest Only Mortgages

  1. Your monthly repayments will be significantly lower because you are not paying any additional contribution to the mortgage equity.

  3. It takes a lot of discipline to save money. It is tempting to think it is easier than it may appear.
