The rate changes will take effect immediately and coincide with the launch of a new 65% LTV deal with a direct rate of 2.85%.
The fixed rate cuts apply on all ranges up to 85% LTV across two, three and five year options. Lifetime trackers are reduced at 80%, 85%, and 90% LTV.
Post Office director of personal lending, Marco Hughes, said: "We constantly review our mortgage range to ensure we are offering customers choice and value for money. Through these latest reductions, customers can benefit from our lowest fixed rate ever, at just 2.85% for two years.”
In addition to the new buy to let lifetime tracker, rates have also been cut across the three year and five year fixed options, by 0.64% and 0.60% respectively.
