The fees-assisted options are priced at 5.34% up to 90% LTV and 6.39% up to 95% LTV, with no completion fee, a free valuation and free legals on remortgages, and a £199 booking fee.
All deals have no higher lending charge, allow 10% capital repayments each year without penalty and have tapered early repayment charges of 5% in years one and two, 4% in year three, 3% in year four and 2% in year five.
Kim Rebecchi, sales and marketing director at Leeds Building Society, said: “These deals deliver certainty and peace of mind on what is often the biggest monthly outgoing for many households, at a very affordable rate and at a time when people are seeing other bills continue to rise.
“We have significantly increased our lending this year and believe that these products will stimulate further homeownership at an affordable rate and support the wider economy.”
