Bank of Mum and Dad: more critical than ever for first-time buyers

Why family support matters for first-time buyers

For many first-time buyers, getting together a deposit is one of the biggest hurdles. When savings are stretched by rising living costs and house prices, support from family—often described as the “Bank of Mum and Dad”—can help you move from waiting to buying.

Family help can take many forms: a contribution towards the deposit, support with purchase costs, or arrangements that affect how the mortgage is structured. Because these contributions can involve significant sums, it’s best to treat them as a financial arrangement with clear terms—not just a gesture.

Common ways the “Bank of Mum and Dad” shows up

Family support isn’t one-size-fits-all. What matters is how the money is intended to work in practice, both for the buyer and for the people providing the funds.

Typical examples include:

• A deposit contribution (a lump sum towards the deposit)
• Support with buying costs (for example, Stamp Duty and legal fees)
• A gift (money that doesn’t need to be repaid)
• A loan (money expected to be repaid)
• Mortgage support (for example, joint borrowing or other forms of support agreed as part of the mortgage application)

Understanding what’s being offered—and on what terms—helps avoid misunderstandings later, especially if circumstances change.

Key decisions to make before any money is handed over

1) How much support is available, and when?

Start with the practical details:

• the amount available
• when it will be provided
• whether it’s intended to cover deposit only or also purchase costs

Timing can affect your mortgage application process and your ability to move quickly once a property is found.

2) Is it a gift or a loan?

This is one of the most important clarifications. The label matters, but so does the reality of the arrangement.

• Gifted money: often used for deposit funding, but it may still have wider implications.
• Loaned money: can give the family provider more control, but it may be treated as debt in the buyer’s overall financial picture.

If the arrangement is unclear, it can create problems for both parties and may complicate the mortgage process.

3) Are there any conditions or restrictions?

Some family support comes with expectations, such as:

• the funds must be used for the deposit
• the money should not be used for other expenses
• what happens if the buyer’s circumstances change

If there are any conditions, it’s better to discuss them early and document them clearly.

4) What happens if the relationship changes?

If the buyer is purchasing with a partner (or someone else), family contributions can become sensitive if the relationship ends.

Planning for this scenario in advance can help protect the intention behind the support and reduce the risk of disputes.

5) Is there written documentation?

Not every family arrangement is documented, but when money is being lent or gifted, having clear paperwork can be valuable.

Written agreements help ensure everyone understands what was agreed and can support the buyer’s position if questions arise later.

How family support can affect a mortgage application

Mortgage lenders generally want to understand the source and nature of any deposit contribution. That means the way family support is structured can influence how the application is assessed.

In practice, helpful preparation often includes:

• ensuring the deposit source is clear
• confirming whether the arrangement is a gift or a loan
• keeping documentation consistent with what’s being claimed
• making sure the buyer’s overall monthly commitments remain affordable

A broker can help translate the family arrangement into a mortgage application approach that’s clear and well presented.

If it’s a gift: common considerations for families

A gifted deposit can be an effective way to help a first-time buyer, but it’s worth considering the bigger picture.

Inheritance Tax (IHT) and timing

Gifts may have implications for Inheritance Tax depending on how long the gift is made before death. The timing of any gift can therefore matter.

Protecting the intention behind the gift

Where the buyer is purchasing with someone else, it’s important to consider how the gift is treated if the relationship changes. Documentation such as a declaration of trust (sometimes referred to as a deed of trust) can help reflect the intended ownership position.

Practical affordability for the family provider

Before making a gift, families often benefit from checking that they can still:

• maintain their own savings and emergency funds
• support their preferred retirement plans
• manage unexpected costs

A deposit gift should not create financial strain for the person providing it.

If it’s a loan: budgeting and lender considerations

A loan from family can offer a clearer repayment expectation, but it should be treated seriously.

Repayment expectations

Even if repayments are intended to be flexible, the buyer should consider:

• what repayments could look like over time
• whether repayments would still be manageable if income changes
• whether relying on future savings is realistic

Mortgage acceptance and how lenders view it

Some lenders may have restrictions on loaned deposit funds. The exact approach can vary, so it’s important that the arrangement is aligned with what the mortgage process can accommodate.

Tax on interest (if interest is charged)

If a family member charges interest on the loan, there may be tax implications for the family provider depending on the structure of the arrangement.

When the buyer is purchasing with someone else

Family support can become more complex when more than one person is involved in the purchase.

Two common tools used to reflect contributions include:

• Declaration of trust / deed of trust: can record who the gifted funds are intended to benefit.
• Living Together Agreement: can set out details of contributions and what happens if the relationship ends.

These documents don’t replace legal advice, but they can help ensure the financial intention behind family support is properly recorded.

Alternatives when family support isn’t available

Family help isn’t the only way to reduce the deposit burden. Depending on circumstances, other routes may include:

Low-deposit mortgage options (where available)

Some mortgage products may allow a smaller deposit than standard options. Availability and affordability considerations still apply.

Shared ownership

Shared ownership can reduce the amount you need to borrow and may lower the deposit required by allowing you to buy a share of the property and pay rent on the remainder.

First-time buyer savings strategies

Some savings approaches are designed to help first-time buyers build a deposit more efficiently. Rules and availability can vary, so it’s important to understand the details.

Government-backed routes (where eligible)

Certain government-supported schemes may help reduce the deposit requirement for qualifying buyers. Eligibility, property restrictions and repayment terms can apply.

Making family support work—without losing control

The “Bank of Mum and Dad” can be a powerful way to help a first-time buyer get onto the property ladder. It tends to work best when the arrangement is planned properly.

A sensible approach often includes:

• confirming the amount and timing
• clarifying whether it’s a gift or a loan
• agreeing any restrictions and how changes in circumstances are handled
• documenting the arrangement clearly
• checking that the buyer’s mortgage and overall outgoings remain sustainable

When family support is handled transparently and professionally, it can reduce uncertainty and help everyone focus on choosing the right home.
