Paradigm member firms will now also be able to access the building society’s reverse JBSP mortgage, which allows the child to help a parent with affordability.

The addition of Buckinghamshire to the panel also means brokers can access the Family Assist product, which offers an alternative to 90% LTV-plus lending. It comes with a 40-year term and allows the applicant to borrow 100% of the purchase price by taking a collateral charge on either the parents’ or grandparents’ property.

The society also offers CARE mortgage products specifically for NHS and Emergency workers plus later life lending with no maximum age at entry or exit of the mortgage, for both residential and buy-to-let.

It provides impaired lending including bankruptcy, IVAs and debt management, up to 60% LTV as well as debt consolidation up to 75% LTV.

Buckinghamshire’s range also includes individual, limited company and expat buy-to-lets products, including a day one remortgage.

Tim Vigeon, head of lending at the Buckinghamshire Building Society, said: “This is a great time to be joining Paradigm Mortgages Services; with our innovative mortgage proposition including our flexible and bespoke underwriting approach we feel we can provide extra support to Paradigm members.”

John Coffield, head of mortgages at Paradigm Mortgage Services, added: “At Paradigm we always want to work with lenders who push the envelope, and we are therefore very pleased to be bringing the Buckinghamshire Building Society to our members.

“The Buckinghamshire clearly look for specific customer needs in the mortgage market and tailor their proposition to this, with a range of unique and highly targeted products available in both the residential and buy-to-let spaces.

“We know that many of our member firms will have clients for whom these products are undoubtedly needed, and we are looking forward to working with the team at the Buckinghamshire to highlight their offering our advisers.”
