Rates for the 80% LTV product start at 3.89% for a 2-year fixed-rate mortgage and 4.15% for a 5-year fixed-rate mortgage, for purchases and remortgage on standard properties.

The maximum loan amount is up to £750,000.

Paul Fryers, managing director at Zephyr Homeloans, said: “Since Zephyr entered the market two years ago, we have established ourselves as a lender that is finely attuned to the needs of specialist and portfolio buy-to-let (BTL) landlords.

“Our 80% LTV mortgages are competitively priced and available to both individuals and limited companies – and will further enable intermediaries to serve the needs of buy-to let borrowers.”

“Given the competitive nature of the property market, processing cases quickly has never been more important, and last month we answered 90% of calls within 30 seconds – and actioned all DIP referrals within 24 hours.”
