Kris Brewster, head of products, at Skipton Building Society, said: “Thanks to our prudent approach to lending, buy-to-let has always been a valuable and high-performing part of our mortgage portfolio. Our buy-to-let deals continue to prove popular and we are delighted to offer this refreshed fixed-rate BTL mortgage range with lower interest rates.
“We believe the range offers great value for purchasers of buy-to- let property and for those wishing to remortgage their portfolio.”
Alex Reynolds, IFA at Advies Private Clients LLP, based in London, said: “They [the products] sound relatively competitive. Having a lower fee and a fee-free option is good for those who are not borrowing a large amount of money.
“As brokers, we have to ensure that we pick the deal that is best suited to our client’s needs, not just the one with the lowest interest rates.
He added: “Lenders have no problem in securing cheap money which provides borrowers with a great opportunity to secure a mortgage and get on the housing ladder.”
