An interest only mortgage means during the term, you only pay off interest, instead of the money borrowed from a lender. At the end of the term, you pay off all the money borrowed at once.

How does an interest only mortgage work?

You borrow the money to buy a home, but only pay back the interest.
The amount you pay each month may be lower than a repayment mortgage, because you aren’t repaying the money borrowed at the same time.
The amount you borrow won’t go down during the term of your mortgage.
You will need to repay the money borrowed for the home at the end of the term with a repayment strategy.

What can you use as a repayment strategy?

You will need to tell you lender about how you’ll pay off the money at the end of your mortgage term.

At the start and during the term, you’ll need to show them evidence of how you plan to do this.

There are lots of ways you can pay off an interest only mortgage:

Sale of the property 

You can sell the home at the end of the term to pay back what you is owed. There are rules around this:
