Why should you use an adviser to look at a product transfer/ rate switch as opposed to go direct to the lender-

Today I have seen a client that was going to go direct and settle for a 2.64% fixed rate with the lender over 5 years, the loan to valuation was 80.12%
I have made them aware that if they wait a month (May) they will be below 80% loan to valuation and as such if rates remain the same the rate will be 1.89% just for waiting a few weeks this will save the clients £3,206.51 per year in interest on their mortgage over 5 years this totals £16,032.56 interest saved. This is why you should always get advice for product transfers/ rate switches- This just goes to show the value of advice and the value of sometimes not rushing in and making wrong decisions.
They always say if you think a professional is expensive, wait until you use an amateur (by the way we dont charge for product transfers)
