Brad Fordham, Managing Director of Santander for Intermediaries, said: “The buy-to-let market has slowed in recent months, but appetite for investing in property remains. We hope that by reducing the product fee on our BTL products, we will support this area of the market and help those who want to invest make their ambition become a reality.”
