The remortgage specials also have their £125 fee waived in addition to retaining the free valuation and £250 cashback.
Jeff Knight, director of marketing at Foundation Home Loans, said: “We have seen significant growth across our buy-to-let range in 2019, particularly in terms of servicing portfolio landlords and developing our limited company offering.
"We recently enhanced our residential criteria and are now doing the same for buy-to-let to ensure we continue to provide more solutions to more intermediaries in 2020. So, if intermediaries are looking for a home for their more complex buy-to-let cases, it’s solution found at Foundation.”
