The green reward five-year fixed-rate mortgages for landlord borrowers are available on PRS properties that have an EPC rating of ‘C’ or above, dated within the last 12 months — except for listed properties which are not eligible.

George Gee, commercial director at Foundation, said: “These rate cuts to some of our most popular five-year fixes are designed to support advisers and their landlord clients, particularly if they are looking for a more generous loan amount.

“The cuts of 10 basis points make these even more competitive and will enhance our core range, supporting those landlords looking to add to their portfolios or remortgage to an excellent rate.

“As always, our aim here is to support those landlord borrowers who just miss out on mainstream credit scores and our adviser partners as they seek to grow their BTL advice businesses.”
