The society offers a 2-year fixed-rate buy-to-let mortgage at 3.24% and a 2-year tracker at 2.84%, each with a £199 fee.
Both mortgages are available up to 60% LTV and come with a range of benefits, including free standard valuation up to £335 and free in-house legal services for remortgages.
Martin Richardson, general manager at Leeds Building Society, said: “We’re pleased to have been able to reduce the product fees on these competitive mortgages.
“In addition to the assisted fees, benefits including free valuation and legal services will bring down the upfront costs of the deal even further.”
