Foundation has reduced rates and introduced new products within its specialist buy-to-let (BTL) range, with reductions of up to 30 basis points.
The changes apply to a large part of the Foundation’s specialist BTL offering, which includes standard and large healthcare organisations, plus MUFBs, where interest rates have been reduced by up to 30 basis points and now start at 4.24%.
The lender has also introduced new two- and five-year fixed rate products with a 3% fee at loan-to-value (LTV) of 65%, 75% and 80% for both standard HMO and MUFB properties.
Rates have also been reduced by up to 15 basis points for short-term rental and vacation rental products, with rates starting from 5.99%.
Rates on two F3 products have also been reduced by 30 basis points, with both two- and five-year fixed rates (with a 2% fee) now available at 6.54% and 6.34% respectively.
Foundation has also introduced two new fixed-rate products for expat borrowers.
Both are aimed at F1 borrowers with both 65% and 75% LTV options, and rates start at 4.39% for two years (3% fee) and 5.09% for five years (4% fee).
Rates have also been reduced on the lender’s property plus, HMO Plus, STL Plus, MPOTs, Mixed Use and Mixed Use Expat products.
Grant Hendry, Foundation Sales Director, said: “Specialist buying and letting activity remains a core focus for us and these latest rate cuts underline our commitment to supporting estate agents in a wide range of cases.”
“By reducing prices on many of our specialist products, we are strengthening both the breadth of our range and our reliability as a lending partner in a market where brokers and their clients need options they can rely on.”
“Our proposition is built around flexibility. From HMOs and MUFBs to short-term rentals, vacation rentals and mixed-use, we aim to provide agents with products that work for real-world scenarios.”
“This combination of lower rates and new fixed rate options at different LTVs gives agents more control when placing business for their landlord clients.”
Elsewhere, Suffolk Building Society has introduced rate cuts of up to 26 basis points on its fixed rate, 80% LTV, BTL mortgages.
BTL mortgages for two and five year fixed rate expats will both be reduced, with reductions of up to 15 basis points, and holiday rentals for two and five year fixed rate expats will be reduced by up to 19 basis points.
The BTL five-year fixed rate and the BTL five-year fixed rate for light renovations will be reduced by as much as 26 basis points, and the BTL two-year fixed rate will be reduced by 14 basis points.
The holiday rental with a five-year fixed interest rate and the holiday rental with a two-year fixed interest rate will be reduced by 14 basis points and 10 basis points respectively.
Suffolk Building Society head of intermediaries Charlotte Grimshaw said: “Landlords could do with some good news right now. With taxes on rental income set to change in 2027, and the changes brought about by the Renters Right Act (2025), landlords continue to face challenges and new standards. Reducing our buy-to-let rates is a practical way to provide support where we can.”
“However, a good rate won’t get off the ground unless it’s backed by good criteria. So in addition to these reductions, we’re maintaining our flexible criteria to support borrowers who need a little more leeway on some of the nuanced aspects of their circumstances, whether they live abroad or are looking for a regulated BTL for a family member.”
