Keeping us up to date

The customer needs to:

  • Keep us informed of any changes to their repayment strategy, which might affect their ability to repay the mortgage at the end of the term. Where they have concerns they can contact us.

  • We expect that as their broker, if you review your customers’ finances in the future, that you would review their repayment strategies and ensure the customer keeps us informed of any changes in their circumstances.

Risks associated with an interest only mortgage

  • The amount of the loan outstanding will not reduce over the period of their mortgage – so they’ll pay interest on the full sum borrowed throughout the term and be more exposed to interest rate changes.

  • There is a greater negative equity risk than a repayment mortgage, which means they could end up owing more than their property is worth.
