Vernon Drops 50% Repayment Test for Family-Supported Mortgages

Families whose combined finances could support a mortgage have sometimes been held back by a separate test: whether the person buying the home could afford half the monthly payment alone. Vernon Building Society has removed that requirement from its joint borrower sole proprietor criteria and widened its approach to age and retirement.

The changes give parents more scope to support a child’s purchase and could also help adult children support older homeowners. Under a joint borrower sole proprietor mortgage, usually shortened to JBSP, family members can add their income to an application without becoming legal owners of the property.

Vernon set out the revised proposition in an announcement published on 6 November. An earlier broker update dated 12 October had already recorded removal of the 50% test and the age-75 cap, so those changes predate the latest publicity.

The practical opening is for families whose previous application was constrained by those rules. Affordability now turns on the combined circumstances of the borrowers, with each person assessed individually.

Why the old 50% test could stop a family-backed purchase

A first-time buyer may have saved a deposit and found a suitable home, yet be unable to borrow enough on their own earnings. A parent with sufficient income might be willing to join the mortgage to help bridge that gap.

The previous rule imposed an additional hurdle. Even with family support, the property-owning borrower had to demonstrate that they could afford at least half the monthly mortgage payment.

For illustration, if the assessed payment were £1,800, that test would require the owner to support £900. Someone assessed as able to afford £750 would fall short of that particular condition, however strong the supporting borrower’s position appeared.

Removing the test allows the lender to consider the family’s combined position without that fixed division. It could make a difference for a professional early in their career, a household temporarily reliant on one salary or a buyer whose earnings are expected to develop.

Future prospects alone do not pay today’s mortgage. The opportunity comes from the supporting borrower’s assessable resources and the affordability of the whole arrangement.

Approaching retirement need not end the discussion

The term change addresses another obstacle. If a supporting parent is nearing retirement, a requirement to finish the mortgage by that date can force the borrowing into a short repayment period.

Repaying the same balance over fewer years normally produces a higher monthly payment. That can undermine affordability even where the parent has a credible income after leaving work.

Vernon’s revised approach allows the mortgage term to extend beyond the supporting borrower’s intended retirement age. Its announcement also confirms no fixed maximum age for capital-repayment mortgages.

For a parent aged 62 who plans to retire at 67, the discussion can therefore extend beyond a five-year horizon. What matters is the income available through the proposed term, including the transition from earnings to retirement income.

The flexibility gives families more room to structure a viable loan. It does not make a pension forecast interchangeable with a current salary or remove the need to consider how retirement spending will change.

Family support can work in the other direction

Much of the attention around family mortgages concerns parents helping children buy. The same separation of borrowing and ownership can be useful when an adult child supports a parent.

An older homeowner might have substantial equity but insufficient income for the refinancing they want. A working son or daughter may be able to join the mortgage while the parent remains the property owner.

Vernon specifically identifies these reverse JBSP cases as a potential beneficiary of its greater age and term flexibility. The option could be relevant to a move, a remortgage or another eligible residential borrowing requirement.

The adult child’s own finances remain central. Their existing mortgage, dependants and other commitments affect how much support they can provide. Family wealth may be substantial, but an application still needs an income structure that supports the payments.

Different parts of the mortgage can run for different periods

The proposition continues to offer split repayment terms, allowing portions of the same mortgage to be repaid over different timescales. This can help align the borrowing with the period over which family support is expected to be available.

As a structural illustration, a £300,000 mortgage might comprise £100,000 repaid over ten years and £200,000 over 25 years. The shorter portion could be designed to reduce the debt more quickly while the supporting family member remains comfortably able to contribute.

That structure normally creates a higher initial payment than spreading the entire balance over 25 years at the same rate. The benefit is faster repayment of part of the loan, rather than an automatic reduction in the family’s immediate outgoings.

Splitting repayment periods also does not, by itself, divide each borrower’s legal responsibility into separate pieces. Nor does clearing one portion automatically release a supporting relative from the remaining mortgage.

More incomes can help, but the commitments come with them

Vernon continues to consider up to four applicants and incomes. Its announcement also describes a broad approach to earnings, including regular bonuses, overtime and allowances, alongside certain less conventional employment arrangements.

For a family with mixed income sources, that can create a fuller assessment than a basic-salary comparison suggests. Manual underwriting provides scope to examine the circumstances behind the figures.

Each additional borrower also brings their own expenditure and liabilities. Adding a parent or sibling is therefore more involved than combining gross salaries and multiplying the total by a standard lending figure.

The application needs to establish what each person can realistically support while maintaining their own household. The revised criteria provide flexibility in that assessment, rather than a promise that every additional income increases the loan by a predictable amount.

Helping without taking ownership still means taking on debt

For some families, JBSP offers a way to help without making a large immediate gift or becoming a co-owner. That may suit parents who prefer to retain savings or investments while supporting their child’s borrowing.

The commitment is substantial. Vernon’s product page makes clear that all borrowers are responsible for paying the mortgage. MoneyHelper explains that joint borrowers can each be responsible for the whole debt if another borrower does not pay.

A family agreement that the child will make every payment does not remove the parent’s obligation to the lender. Joint borrowing also appears on credit records, with missed payments potentially affecting the other borrowers.

Families therefore need a clear discussion about contributions, retirement and how support might eventually end. Independent legal advice helps the supporting borrower understand the responsibility they are accepting without acquiring ownership.

Previously unsuccessful family cases deserve another look

The strongest immediate opportunity is for a purchase or remortgage that fell short because the owner could not meet the 50% test, or because a supporting borrower’s age restricted the term.

A review can establish whether those were the decisive barriers and whether the revised approach changes the outcome. Deposit requirements, acceptable relationships, retirement-income evidence and current product terms still need to fit the case.

Willow can assess the owner’s plans alongside the wider family’s income and commitments, including how support could be reduced or removed later. For families with the means to help but an arrangement that previously failed the criteria, Vernon’s changes create a useful reason to reopen the conversation.
