The premier range offers mortgage loans ranging from £600,000 to £1m to 70% LTV, while options for multi-unit properties are also available.
David Whittaker, managing director of Keystone Buy to Let Mortgages, said: “Our products are criteria rather than price led but being able to reduce the 5-year fixed rates demonstrates our all-round commitment to support landlords in a market with rates at an all-time low.”
Borrowers using the classic 5-year range can also take out loans on HMOs and multi-units to 70% LTV.
