Accord Mortgages has made cuts of 0.10 percentage points to its range of low fee fixed and tracker rate buy-to-let products, which feature fees of £395.
It has also made changes to early repayment charges and extended end dates until 31 August on all buy-to-let products.
Two and three year products now include stepped ERCs, while repayment charges on the five year mortgage fall to 2% and 1% in the final two years of the fixed period.
Rates for the low fee products are 3.89% for the two year fixed rate and 3.39% plus Bank of England base rate for the two year tracker, 3.99% for the three year fixed rate and 4.29% for the five year fixed rate.
All of the £395 fee products include £500 cashback on completion and are available for house purchase or remortgage.
All Accord Buy to Let mortgages are available up to a maximum of 75% loan to value.
Toni Roberts, Accord product manager, said: “Our low-fee products help us to provide a broad range of mortgages suitable for a variety of customers.
“The reduction in mortgage rate on these products will help to lower the costs for borrowers while the changes to the early repayment charges are also good news for them.”
