The lender said its JBSP product has proved a popular niche offering, offering older individuals  the opportunity to assist younger borrowers who are unable to afford the total mortgage loan based on their income and circumstances.

And it also offers ‘reverse Joint Borrower Sole Proprietor’ mortgages, which enables younger borrowers to help older buyers who are already retired or heading towards retirement.

Another specialist lending product which the Society offers is a split term loan, allowing younger borrowers to repay a section of the loan over a longer term, with the older borrower supporting the shortfall in payments over a smaller term.

Split term loans work particularly well with Joint Borrower Sole Proprietor products and minimise the monthly payment of the loan, making a mortgage more affordable for the buyer.

Emily Smith, national account manager at Hinckley & Rugby Building Society said: “We are so pleased to have reintroduced our Joint Borrower Sole Proprietor 90% LTV products.

“These products have been extremely popular in the past and will enable borrowers who have smaller deposits and lower incomes to get on the housing ladder.

“Coupled with our split term initiative, these products allow for more affordable repayments when adding an older relative to the loan.”

Products include a five-year fixed rate deal at 3.69%, a two-year fixed at 3.49% and a two-year discount mortgage at 3.19%, all at 90% LTV.

Hinckley & Rugby Building Society allows four applicants on a Joint Borrower Sole Proprietor Mortgage with all incomes considered.
