This offer has no higher lending charge and allows 10% capital repayments each year without penalty.
Kim Rebecchi, Leeds Building Society Sales and Marketing Director said:
"We believe it's a very good time to lock into a low fixed rate, and have reduced the rate by 0.36% on the 2 year buy to let deal to a new market leading rate of 3.99% available up to 65% LTV.
"This flat fee product will attract professional landlords, who may wish to move onto a market leading rate and fix their monthly commitments."
