Martin Reynolds, corporate manager at PMS, says: “With the continuing uncertainty in the economy and volatility of the money markets having the security of a longer term fixed may be a viable option. We are delighted to be working alongside Astra with this exclusive product.
Stewart Hunter, head of introduced mortgages at Astra, says: “The broker mortgage market needs more long-term fixed rate products at lower rates to bring greater payment stability for borrowers.”
