Metro Bank has added a number of products at 85% and 90% LTV.
At the 90% LTV tier, the specialist lender has introduced 2 and 3-year fixed rate mortgages, priced from 3.19%.
In addition, the maximum loan size has increased to £675,000 from £540,000.
The bank is also offering 85% LTV products, with 2, 3 and 5-year fixed options available with rates starting from 2.89%.
The maximum loan size for these products have also been increased, to £850,000 from £510,000.
Furthermore, the lender is cutting its stress test rate on 5-year BTL mortgages, from 4.5% to 4%.
Charles Morley, director of mortgage distribution at Metro Bank, said: “The higher LTV market has been very active as of late with many lenders stepping back into the fold.
“Metro Bank is proud to have remained in this market throughout, whilst reducing rates and expanding our product range in recent weeks.
“We’re listening to the needs of both our customers and our intermediary partners, delivering a substantial number of specialist upgrades and continuing to offer a range of products that are as individual as our customers are.”
