Family Assist Mortgages: Helping Families Get onto the Property Ladder
What Is a Family Assist Mortgage?
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
The most straightforward form of family assistance is a gifted deposit, where a family member provides money towards the deposit that does not need to be repaid. A larger deposit reduces the loan-to-value ratio on the mortgage, which typically gives the buyer access to more competitive interest rates and a wider choice of lenders.
Lenders require written confirmation that the deposit is a genuine gift with no expectation of repayment, and that the person providing it has no financial interest in the property. The gifting family member will typically need to sign a gifted deposit letter and in some cases provide bank statements to evidence the source of funds. We will guide you through exactly what documentation each lender requires.
It is worth noting that a gifted deposit may have inheritance tax implications for the family member providing it, depending on their circumstances. Gifts made within seven years of death may form part of the donor's estate for inheritance tax purposes. Independent legal or financial planning advice is recommended for larger gifts.
Family guarantee mortgage
A family guarantee mortgage, sometimes called a family springboard or family support mortgage depending on the lender, allows a family member to use their own property equity or savings as additional security for the buyer's mortgage. This can enable the buyer to borrow more than they could on their own, or to purchase with a smaller deposit, while the family member does not need to hand over any cash.
The family member's property or savings are held as security by the lender for an agreed period, typically between three and five years, after which they are released provided the buyer has maintained their mortgage payments. During this period, the family member cannot usually sell or remortgage the property used as security without the lender's consent.
This is a significant commitment for the family member. If the buyer defaults on their mortgage, the lender may call upon the guarantee, which could put the family member's property or savings at risk. Independent legal advice is strongly recommended for anyone acting as guarantor before entering into this type of arrangement.
Joint borrower sole proprietor mortgage
A joint borrower sole proprietor (JBSP) mortgage is an arrangement where a family member's income is included in the affordability assessment alongside the buyer's, allowing the buyer to borrow more than they could on their own. Crucially, the family member is named on the mortgage as a co-borrower and is therefore jointly liable for the repayments, but they are not named on the title deeds and do not have a legal ownership interest in the property.
This structure avoids the additional Stamp Duty Land Tax surcharge that would apply if the family member were named as a joint owner and already owns a property themselves. It also means the buyer's first-time buyer status is preserved for Stamp Duty relief purposes, provided they have not previously owned a property.
JBSP mortgages are assessed on the combined income of all borrowers, but lenders also take into account the family member's existing financial commitments, including their own mortgage or rent payments. Affordability is assessed carefully to ensure the arrangement is sustainable for all parties.
Part gift, part loan arrangements
Some family members are willing and able to provide financial support but want the option to be repaid in future rather than treating the full amount as a gift. In these cases, it is possible to structure the contribution as part gift and part loan, or as a full loan from a family member, provided this is clearly documented and disclosed to the lender.
Lenders treat loaned deposits differently from gifted deposits. A loaned deposit is a financial commitment that affects the buyer's affordability calculation, because the lender will account for any repayments due on the loan. The arrangement must be fully disclosed and documented. A formal legal agreement between family members is strongly recommended to protect both parties and to satisfy lender requirements.
Key Considerations for Family Assist Mortgages
Implications for the supporting family member
Anyone providing financial support for a family member's mortgage should fully understand what they are committing to before proceeding. For guarantors or JBSP co-borrowers, the mortgage will typically appear on their credit file and will be factored into any future mortgage or credit applications they make. If the buyer misses payments, this will affect the family member's credit profile as well as their own.
For those using their property as security in a guarantee arrangement, the risk is more direct. Default by the buyer could ultimately result in a claim against the guarantor's property. This is not a common outcome, but it is a real risk that must be properly understood before entering into the arrangement.
Stamp Duty implications
The Stamp Duty position depends on the structure of the arrangement. If a family member is named as a joint owner on the title deeds and already owns a property, the additional Stamp Duty surcharge for second properties will apply to the entire purchase price. A JBSP mortgage avoids this by keeping the family member off the deeds. This is one of several reasons why the choice of structure matters and why proper advice is important.
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, depending on the total value of their estate and any applicable exemptions. Each individual has an annual gift exemption of £3,000, and gifts out of normal income may also be exempt. For larger gifted deposits, it is worth speaking with a financial planner or solicitor to understand the inheritance tax position before proceeding.
Independent legal advice
For guarantee arrangements and JBSP mortgages, most lenders will require the family member to take independent legal advice before the mortgage completes. This is to ensure they fully understand the commitment they are making and the risks involved. This is a sensible safeguard and we would encourage all family members providing any form of mortgage assistance to seek independent advice regardless of whether it is formally required.
How the Family Assist Mortgage Process Works
Step 1: Understanding your situation
We begin by understanding the buyer's income, deposit position, and what they are trying to achieve, alongside the family member's financial position and what form of support they are comfortable providing. This shapes which structure is most appropriate.
Step 2: Selecting the right structure and lender
Different lenders have different policies on gifted deposits, guarantee arrangements, and JBSP mortgages. Not all lenders accept all structures, and the terms and criteria vary considerably. We identify the lenders whose approach best fits your specific arrangement and search for the most competitive product within that panel.
Step 3: Preparing documentation
Family assist applications typically require more documentation than standard mortgage applications. This includes gifted deposit letters, evidence of the source of gift funds, property valuations for guarantee arrangements, full financial information for all borrowers, and in some cases independent legal advice certificates. We guide you through exactly what is needed and help you prepare it correctly.
Step 4: Application and completion
We submit the application, manage lender queries, and keep all parties informed throughout the process. Once approved, we ensure everyone understands their obligations and the ongoing implications of the arrangement 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, whether it is a gift, a loan, or a guarantee, and what the expectations are on both sides, avoids misunderstandings later.
• Document everything formally. Even within families, it is important that any loan arrangement or guarantee is properly documented in a legal agreement. This protects everyone involved and satisfies lender requirements.
• Seek independent legal advice before entering a guarantee arrangement. Most lenders require this, and it is good practice regardless. An independent solicitor will ensure the family member fully understands their obligations.
• 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 are most effective when they solve a short-term deposit or borrowing gap, not when they are required to sustain the mortgage on an ongoing basis.
• Check that the supporting family member's own financial position is not put under pressure. Using savings or property equity to support a family member is a generous act, but it should not compromise the family member's own financial security.
