Family Assist Mortgages: Helping Families Get onto the Property Ladder

A family assist mortgage is a mortgage arrangement that allows a family member, typically a parent or grandparent, to help a buyer get onto the property ladder or access a more suitable mortgage than they could achieve on their own. The support can take several different forms depending on the circumstances of both the buyer and the family member providing assistance.

Getting onto the property ladder has become increasingly difficult in recent years, with house prices significantly outpacing wage growth in many parts of the UK. The deposit required to purchase even a modest property can take many years to save, and lenders' income multiples can limit how much buyers can borrow. Family assist mortgages exist to bridge this gap in a structured and responsible way.

At J Finance, we advise both the buyer and the supporting family member through the full range of family assist options, making sure everyone understands the implications before committing to any arrangement.

Types of Family Assist Mortgage

There is no single product called a family assist mortgage. The term covers a range of different structures, each of which works differently and has different implications for both the buyer and the family member providing support.

Gifted Deposit

A family member provides money towards the deposit that does not need to be repaid. A larger deposit reduces the loan-to-value ratio, typically giving access to more competitive rates and a wider choice of lenders.

Lenders require written confirmation that the deposit is a genuine gift with no expectation of repayment, usually including a gifted deposit letter and evidence of the source of funds.

Gifts made within seven years of death may form part of the donor's estate for inheritance tax purposes, so independent legal or financial planning advice is recommended for larger gifts.

Family Guarantee Mortgage

Sometimes called a family springboard or family support mortgage, this allows a family member to use their own property equity or savings as additional security, enabling the buyer to borrow more or purchase with a smaller deposit without any cash changing hands.

The security is held by the lender for an agreed period, typically three to five years, and released once the buyer has maintained their payments. If the buyer defaults, the lender may call upon the guarantee, so independent legal advice is strongly recommended for anyone acting as guarantor.

Joint Borrower Sole Proprietor (JBSP)

A family member's income is included in the affordability assessment alongside the buyer's, allowing the buyer to borrow more. The family member is a co-borrower and jointly liable for repayments, but is not named on the title deeds and has no legal ownership interest.

This avoids the additional Stamp Duty surcharge that would apply if the family member were a joint owner, and preserves the buyer's first-time buyer status for Stamp Duty relief purposes.

Part Gift, Part Loan Arrangements

Where a family member wants the option to be repaid rather than gifting the full amount, the contribution can be structured as part gift and part loan, or as a full loan, provided this is clearly documented and disclosed to the lender.

A loaned deposit affects the buyer's affordability calculation, as the lender accounts for any repayments due. A formal legal agreement between family members is strongly recommended.

Key Considerations for Family Assist Mortgages

Implications for the Supporting Family Member

For guarantors or JBSP co-borrowers, the mortgage will typically appear on their credit file and be factored into any future credit applications. Missed payments by the buyer will affect the family member's credit profile too, and for guarantee arrangements, default could ultimately result in a claim against the guarantor's property.

Stamp Duty Implications

If a family member is named as a joint owner and already owns a property, the additional Stamp Duty surcharge for second properties applies to the entire purchase price. A JBSP mortgage avoids this by keeping the family member off the deeds.

Inheritance Tax on Gifted Deposits

Gifts made within seven years of the donor's death may be subject to inheritance tax as part of their estate. Each individual has an annual gift exemption of £3,000, and gifts out of normal income may also be exempt. Speak with a financial planner or solicitor for larger gifts.

Independent Legal Advice

For guarantee arrangements and JBSP mortgages, most lenders require the family member to take independent legal advice before completion, to ensure they fully understand the commitment and risks involved.

How the Family Assist Mortgage Process Works

1
Understanding Your Situation We begin by understanding the buyer's income and deposit position, and the family member's financial position and what support they are comfortable providing. This shapes which structure is most appropriate.
2
Selecting the Right Structure and Lender Different lenders have different policies on gifted deposits, guarantee arrangements, and JBSP mortgages. We identify the lenders whose approach best fits your specific arrangement.
3
Preparing Documentation Family assist applications typically require gifted deposit letters, evidence of gift funds, property valuations, full financial information for all borrowers, and in some cases legal advice certificates. We guide you through exactly what is needed.
4
Application and Completion We submit the application, manage lender queries, and keep all parties informed throughout, ensuring everyone understands their obligations before completion takes place.

Tips for Families Considering Mortgage Support

  • Have an open and honest conversation as a family before approaching a lender. Agreeing on what form the support will take and the expectations on both sides avoids misunderstandings later.
  • Document everything formally. Even within families, any loan arrangement or guarantee should be properly documented in a legal agreement.
  • Seek independent legal advice before entering a guarantee arrangement. Most lenders require this, and it is good practice regardless.
  • Consider the tax position of any gift. For larger amounts, take advice on the inheritance tax implications before proceeding.
  • Make sure the buyer can genuinely afford the mortgage independently in the long term. Family assist arrangements work best when solving a short-term deposit or borrowing gap, not sustaining the mortgage ongoing.
  • Check that the supporting family member's own financial position is not put under pressure by the arrangement.
