If you have any affordability questions regarding Interest-Only products including our RIO mortgages, contact our Mortgage Desk or your BDM.

Affordability is calculated using our stress rate for all products except for our fixed rate mortgages with a term of five or more years, and our Family Mortgages.
If you would like to check affordability for a RIO mortgage for a single applicant this can be calculated using interest only and a ten-year term. For a joint RIO mortgage as this is more complex, please call us so that we can help with an affordability for you.
