The lender now offers landlords a two-year fixed-rate for purchases with a rate of 1.78% at 75% loan to value (LTV) and a five-year fix at 2.5% and 60% LTV.
Skipton has also launched a range of buy-to-let remortgages offering up to £500 cashback.
All landlord products offer free valuations, and select loans also offer standard legal fees.
At the same time, the lender has reduced rates on a range of five-year residential products, including a 2.65% to 90% LTV for purchases, and a remortgage deal at 2.19% at 85% LTV.
Kris Brewster, Skipton’s head of products (pictured), said: “We are delighted to launch this refreshed fixed-rate buy-to-let mortgage range offering lower interest rates.
“Skipton’s buy-to-let deals continue to prove popular and we believe this new range offers great value for purchasers of buy-to-let property and for those wishing to remortgage their portfolio.
“Skipton’s five-year residential fixed range remains a popular choice for both new and existing customers seeking peace of mind knowing that their mortgage payments are fixed for the longer term,” he added.
