Why more buyers rely on family for their deposit

For most first-time buyers, and plenty of movers too, saving a deposit is the hardest part of the whole process. Even at 5% or 10%, the sums involved can take years to put aside, and rising rents make it harder still. It is no surprise that family support has become a normal part of the conversation — not a loophole, and not something to feel awkward about. Lenders are entirely used to it.

What matters is how that support is structured and documented. Whether a relative is gifting money, acting as a guarantor, or joining the mortgage in some other way, the lender will want a clear written record. Get this right early and it rarely causes a problem. Leave it to the week before completion and it can delay or derail the purchase.

Gifted deposits: what lenders want to see

A gift is money handed over with no expectation of repayment and no claim on the property. That is the key distinction. If a relative expects the money back, or expects a share of any future sale proceeds, most lenders will treat it as a loan — and a loan changes your affordability calculation, often reducing how much you can borrow.

Lenders assess gifts as part of their anti-money-laundering checks. In practice you should expect to provide:

• a signed gifted deposit letter from the donor
• proof of the donor's identity, such as a passport or driving licence
• evidence of where the donor's money came from, for example recent bank or savings statements
• bank statements showing the money moving from the donor's account, ideally straight to your solicitor

Lenders generally accept gifts from close family: parents, grandparents, siblings, and sometimes aunts, uncles or in-laws. Most will not accept money from a friend or a more distant relation, so check the lender's policy before you ask anyone to sign anything.

The gifted deposit letter explained

Some lenders provide their own template; others are happy with a clear letter. Either way, the donor should sign and date it, and it should state:

• the donor's full name, address and relationship to you
• the amount being gifted and the date it was or will be transferred
• that the money is a gift, not a loan, and is not repayable
• that the donor will not have any legal or beneficial interest in the property
• that the donor will not live at the property as their main home, if that is the case

Your solicitor will need a copy too, as they carry out their own source-of-funds checks. Where more than one relative is contributing, each should provide a separate declaration. Keep the wording simple and truthful; lenders and conveyancers compare the letter against the bank statements, so inconsistencies stand out.

Guarantor mortgages and other ways relatives can help

Not every family can hand over cash. Guarantor arrangements let a relative support the application without gifting a lump sum.

• Guarantor mortgage: the guarantor is liable if you stop paying. Lenders assess their income, outgoings and existing commitments, and many require them to be a homeowner or to live in the UK.
• Joint borrower, sole proprietor: you and a supporter both go on the mortgage, but only you are named on the property title. Affordability is calculated on combined income.
• Family offset: a relative's savings are linked to your mortgage and offset against the balance, reducing the interest charged. The money usually remains theirs.
• Savings as security: some deals allow a relative's savings to be held as additional security instead of a larger deposit.

Each option has different implications for the relative's own borrowing power and for tax. A guarantor's ability to remortgage or move later can be affected, and the arrangement usually stays in place until the lender agrees to release them.

Practical steps and things people overlook

Talk about the money before you start viewing. Agreeing an amount in principle keeps everyone's expectations realistic, and it lets a broker check which lenders will accept your particular arrangement.

A few details regularly catch buyers out:

• Money that appears in your account without a paper trail invites questions. Have the donor transfer directly to your solicitor where possible.
• A gift does not affect your first-time buyer status or any Lifetime ISA rules, but the money must come from an eligible source.
• Large gifts can have inheritance tax consequences for the donor. Gifts made more than seven years before death are generally outside the estate, and there are allowances for regular gifts out of income.
• If the donor receives means-tested benefits, giving money away can affect their entitlement. They should take advice before transferring anything.
• Tell your solicitor early. They will not act on the purchase until source-of-funds checks are complete.

Family support is a practical route onto the property ladder, and lenders treat it as routine when the paperwork is clear. Be honest about the arrangement, document it properly, and take advice where tax or benefits are involved. Handled that way, help from a relative can smooth the whole purchase rather than complicate it.
