The move is part of the club’s expansion strategy and aims to provide brokers with more solutions for its customers during the current challenging times.

It means brokers will be able to access Buckinghamshire’s Joint Borrower Sole Proprietor with no maximum age, up to a 40-year term, along with its reverse Joint Burrower Sole Proprietor product, which allows children to help out parents.

The building society is also still offering its Family Assist product, which is one of only a few higher LTV products currently available.

It also offers 90% LTV for local residents and society members along with NHS and emergency worker offerings.

Melanie Spencer, head of the MCI Mortgage Club, said: “At MCI Mortgage Club, we are continuously looking for lenders in the market that will offer our clients competitive products and alternatives that allow our clients to achieve their objectives.

“The addition of the Buckinghamshire to our panel gives our members access to some unique products that will enable our brokers to think outside the box.”

Timothy Vigeon, Head of Lending at Buckinghamshire Building Society, said: “We are delighted to be joining MCI Mortgage Club and look forward to working with its members.

“We have been able to innovate our mortgage proposition, to include Family Assist products, and more recently, Reverse Joint Borrower Sole Proprietor (“Bank of Son and Daughter”), alongside our other areas of flexible lending, which we feel will provide extra support to the MCI members.”
