Leeds Building Society has cut is 3-year buy-to-let mortgage rate by 0.25 percentage points.
The fixed rate now sits at 4.14 per cent, with no higher lending charge and allows 10 per cent capital repayments each year without penalty.
It is available up to a 65 per cent loan-to-value (LTV).
Head of intermediary sales at Leeds Building Society Phil Coombes said: “We believe that now is a very good time to lock into a low fixed rate.
“This flat fee product will attract professional landlords, who may wish to fix their monthly commitments.”
