There is a three-year fixed with a rate of 4.39 per cent, available through intermediaries. There is also a three-year fixed set at 3.99 per cent which is available directly to existing members.
The mutual also released a mortgage available to borrowers purchasing properties in the local Buckinghamshire area, at 3.99 per cent. All the products have fees of £350.
The mortgages are not available on new-build properties and loan sizes range from £25,000 to £500,000.
Gifted deposits will not be accepted. Up to two applicants can be on the mortgage and the income multiple is capped at 4.5x for the first income plus 3.5x the second income. Joint incomes will be assessed at 4x.
The society said it expected demand for the products to be high and encouraged brokers to submit applications as soon as possible.
Tim Vigeon (pictured), head of lending at Buckinghamshire Building Society, said: “As a mutually owned building society, we are committed to doing whatever we can to help people get onto the property ladder after what has been an incredibly challenging year.”
He added: “The society assesses applications on a case by case basis, our human approach to underwriting means that we credit search rather than credit score applications, so that we can take a holistic view when reviewing an application rather than relying on a computer-based decision.
“We take time to understand the affordability of the mortgage options so that they are suitable and sustainable for the borrower’s individual circumstances.”
