The figures and estimates shown in this calculator should not be relied on as confirmation of affordability and should only be used as an indicative guide to monthly costs. The monthly rental cost is based on 2.75% on the retained equity (subject to change please ask your sales agent). This will usually increase by the annual rate of RPI. The monthly mortgage cost is based on a Variable Rate Mortgage at 5.50% over a 25-year repayment loan. Other costs will apply such as service charge.

You should always seek advice and recommendations from an independent financial advisor regarding mortgage products, affordability, interest rates, repayment methods and terms and conditions. You should also seek independent legal advice. Your home may be repossessed if you do not keep up payments on a mortgage or any other loan secured against it.
