Can You Buy a House for a Family Member to Live In? Legal and Financial Considerations

Buying a property for a family member to live in — whether it’s a child, ageing parent, or relative in need — is a generous and thoughtful act. In the UK, this kind of arrangement is increasingly common, especially as house prices continue to rise and homeownership becomes more difficult for younger or lower-income individuals.

However, while the idea is simple, the legal and financial considerations involved can be surprisingly complex. From mortgage eligibility to tax implications and ownership structures, there’s a lot to take into account before making the leap.

Whether you’re a homeowner exploring your options or working with local letting agents in Staines-upon-Thames to understand the regional market, this guide will walk you through the key issues you need to know before buying a property for a family member to live in.

Why Buy a House for a Family Member?

There are many reasons why someone might choose to purchase a property for a loved one:

  • Helping adult children onto the property ladder
  • Providing a home for elderly parents or relatives in need of care
  • Supporting a family member with disabilities
  • Offering accommodation for students or young professionals starting out

In many cases, the buyer remains the legal owner while the relative simply resides in the property. But depending on how the arrangement is structured, it can affect everything from your tax position to your mortgage options and even future inheritance planning.

Can You Buy a House for Someone Else to Live In?

Yes — you can buy a property for someone else to live in. However, the way you go about it will determine how the purchase is treated by lenders, HMRC, and legal authorities. Key questions to ask yourself include:

  • Will the occupant pay rent?
  • Will the occupant eventually own part or all of the property?
  • Will I take out a mortgage, or buy the property outright?
  • What are the long-term plans for the property?

Let’s explore the most common approaches and the implications of each.

Option 1: Buy-to-Let Mortgage with a Family Member as Tenant

If your relative will pay rent, even if it’s below market rate, then lenders will typically classify this as a buy-to-let arrangement. You’ll need a buy-to-let mortgage, which comes with:

  • Higher interest rates
  • Larger deposit requirements (usually 25% or more)
  • Stricter affordability criteria

However, many lenders exclude close family tenants from traditional buy-to-let products, as it’s considered higher risk. In such cases, you’ll need a regulated buy-to-let mortgage, specifically designed for landlords renting to family members. These are less common and may require advice from a mortgage broker.

Working with experienced letting agents in Staines-upon-Thames can help ensure the rent and tenancy setup is legally sound and in line with local regulations.

Option 2: Standard Residential Mortgage (If You’ll Be Living There Too)

If you intend to live in the property alongside your family member — for example, in a multi-generational household — then a residential mortgage is possible, as you’re occupying the property yourself.

In this case, lenders will treat it as a primary residence. However, if you later move out and your relative remains, you may need to inform your lender and potentially switch to a consent-to-let agreement or new mortgage product.

Option 3: Buying a Property Outright in Your Name

If you have the funds available, buying a house outright — without a mortgage — is the most straightforward option. You can then allow a relative to live there rent-free or on an informal basis. That said, you should still consider:

  • Tenancy agreements to clarify expectations
  • Insurance coverage for non-owner-occupied homes
  • Whether your relative contributes to household expenses or maintenance

This option also gives you the flexibility to retain ownership while helping a loved one enjoy the security of a stable home.

Option 4: Buying in Joint Names or Gifting a Deposit

Another popular route is to either:

  • Buy the property jointly with the family member
  • Gift a deposit to help them get their own mortgage

Joint ownership allows both parties to benefit from rising property values but also comes with shared liabilities and potential inheritance issues. It’s vital to agree from the outset:

  • How the property is owned (joint tenants vs. tenants in common)
  • What happens if one party wants to sell or move

Legal agreements like a declaration of trust can formalise these arrangements.

Tax Implications to Consider

Buying a property for someone else can affect your tax liabilities in several ways:

1. Stamp Duty

If you already own a property, buying another one means you’ll likely pay the 3% additional Stamp Duty surcharge, even if the property is not for your own use.

2. Capital Gains Tax (CGT)

If the property increases in value and you sell it in future, you could be liable for Capital Gains Tax, as it is not your primary residence.

3. Inheritance Tax (IHT)

Gifting property or paying for someone else’s home can be classed as a potentially exempt transfer (PET), which may have IHT consequences if you pass away within seven years of the gift.

Consulting a tax adviser or solicitor is essential to structure the purchase in a tax-efficient way.

Legal Considerations

Even when buying for family, it’s important to treat the arrangement professionally. Some key legal aspects include:

  • Drafting a tenancy agreement or licence to occupy
  • Clarifying ownership rights in writing
  • Ensuring the property meets rental safety standards, including gas and electrical checks

A reputable letting agent in Staines-upon-Thames can help handle the legal and compliance side if you choose to formalise the arrangement as a rental.

Alternatives to Buying a Property for a Relative

If buying outright or securing a second mortgage isn’t feasible, other options include:

  • Guarantor mortgages – supporting a family member’s application by guaranteeing repayments
  • Joint borrower, sole proprietor mortgages – helping a relative get a mortgage without owning the home yourself
  • Lifetime mortgages or equity release – suitable if you’re helping older relatives downsize or fund care

Each option comes with unique risks and requirements, so always seek independent financial advice.

Conclusion: Plan Carefully and Seek Advice

Buying a house for a family member to live in can be a generous and life-changing decision, but it comes with significant legal and financial considerations. From mortgage types to tax planning and long-term ownership strategy, you’ll need to think through the full picture before committing.

By planning ahead, getting professional advice, and working with trusted letting agents in Staines-upon-Thames, you can create a secure and supportive living arrangement that benefits both you and your loved ones — now and in the future.
