Let’s be honest about what’s happening in the UK property market. The gap between what a first-time buyer can save and what they need to get on the ladder has become so vast that one in four property purchases now involves financial help from family. The “Bank of Mum and Dad” is no longer a cute metaphor \u2014 it’s the ninth-largest mortgage lender in the country by some estimates. And increasingly, that help isn’t coming as a simple gift towards a deposit. It’s arriving as a structured family bridging loan: a short-term advance enabling a child (or grandchild) to move fast, bid competitively, and secure a home before selling an existing property or before other funds land.<\/p>\n
This arrangement can be transformative. It can also be financially catastrophic for everyone involved if done carelessly. Here’s what you actually need to know.<\/p>\n
A commercial bridging loan from a high-street or specialist lender typically costs 0.5%\u20131.5% per month in interest, plus arrangement fees of 1%\u20132% of the loan value. For a \u00a3100,000 bridge, you could easily pay \u00a315,000 in costs over six months. A family bridging loan replaces this with a private arrangement \u2014 often interest-free or at a nominal rate \u2014 where parents lend a lump sum to cover a deposit shortfall, a chain break, or even the full purchase price on a temporary basis, repayable once the borrower’s existing property sells or a mainstream mortgage completes.<\/p>\n
The critical distinction is that this is a loan, not a gift<\/strong>. That distinction matters enormously for mortgage lenders, HMRC, and the courts. Most institutional lenders will accept gifted deposits with a simple signed letter confirming no repayment is expected. But if the money is actually a loan \u2014 repayable in any form, on any timeline \u2014 the lender must<\/strong> factor those repayments into the borrower’s affordability assessment. Disguising a loan as a gift to help your child pass affordability checks is mortgage fraud. Full stop. It is a criminal offence under the Fraud Act 2006, and lenders are increasingly sophisticated at spotting it.<\/p>\n Sometimes parents go further and join the mortgage itself as co-borrowers to boost affordability. If you’re considering this, understand one non-negotiable legal reality: joint and several liability<\/strong> means the lender can pursue either<\/em> borrower for 100% of the outstanding debt. Not half. Not their “fair share.” The entire amount. If your child stops paying, the lender comes to you for everything.<\/p>\n Equally damaging is the effect on future borrowing capacity. When a parent is named on a child’s mortgage, every future lender will stress-test that parent against the full<\/strong> outstanding mortgage debt. A parent wanting to remortgage their own home, release equity, or downsize may find themselves unexpectedly locked out of competitive rates \u2014 or refused entirely.<\/p>\n Here’s a surprise that catches families out at the worst possible moment \u2014 completion day. If either<\/strong> co-buyer already owns residential property anywhere in the world, the 5% Stamp Duty Land Tax higher rate for additional dwellings applies to the entire<\/strong> purchase price. That means a parent joining the title to “help out” on a \u00a3350,000 purchase triggers an additional \u00a317,500 in SDLT \u2014 and the child loses their first-time buyer relief entirely. This single mistake can wipe out years of savings. If you’re lending money rather than going on the title, this trap doesn’t apply, which is another strong argument for structuring help as a loan rather than co-ownership.<\/p>\n If parents do take a beneficial interest in the property (rather than simply lending money), a Declaration of Trust (sometimes called a Deed of Trust) is not optional. Without one, the legal presumption for co-owners is equal beneficial shares \u2014 regardless of who actually contributed what. A parent who put in 80% of the deposit could be legally entitled to only 50% of the equity on sale.<\/p>\n The Declaration of Trust should specify:<\/p>\n Execute this as a deed<\/strong>, not a simple contract. Obligations under a deed carry a 12-year limitation period compared to just 6 years for a standard contract \u2014 giving significantly longer enforceability.<\/p>\n Under the Trusts of Land and Appointment of Trustees Act 1996, either<\/strong> co-owner can apply to the court to force a sale of the property, even if the other party refuses. This is not theoretical \u2014 it happens regularly in family disputes, relationship breakdowns, and situations where one party needs their money back urgently. Without a robust co-ownership agreement addressing exit mechanisms, you’re one family argument away from expensive, protracted litigation. A well-drafted agreement with mediation clauses and buy-out timelines can prevent a TOLATA application from ever becoming necessary.<\/p>\n If the property is the child’s main residence and the parents never live there, Capital Gains Tax becomes relevant to the parents’ share on sale. Principal Private Residence Relief only applies to the proportion of the property that was the owner’s actual<\/strong> main home during ownership. Parents holding a beneficial interest in a property they’ve never lived in will face CGT on any gain attributable to their share at rates of 18% or 24% depending on their tax band.<\/p>\n There are also Inheritance Tax considerations. If parents lend money interest-free, HMRC may treat the foregone interest as a transfer of value. More significantly, if a parent gifts their share of the property to the child but continues to benefit from it in any way (for instance, receiving rental income or living there), the gift with reservation of benefit rules mean the asset remains in the parent’s estate for IHT purposes.<\/p>\n Whether or not parents take an interest in the property, the loan itself needs a formal written agreement covering:<\/p>\n A family bridging loan can genuinely be the difference between securing a home and watching it slip away. But the families who benefit most are those who treat the arrangement with the same rigour a commercial lender would. Instruct a solicitor \u2014 ideally one for each side to avoid conflicts of interest \u2014 to draft both the loan agreement and any Declaration of Trust as formal deeds. Get independent financial advice on the tax consequences for both parties before<\/em> completion. And have the uncomfortable conversations about default, forced sale, and death before a single pound changes hands. The cost of proper legal documentation is typically \u00a31,000\u2013\u00a32,500. The cost of getting it wrong can be the family home \u2014 and the family itself.<\/p>\n Disclaimer:<\/strong> The information provided in this article is for informational purposes only and should not be considered financial or legal advice.
