How Families Help First‑Time Buyers including gifted deposits: Key Options, Risks & Tax Considerations
Parents and grandparents now regularly support first time buyers through gifted deposits, family loans, joint borrower sole proprietor (JBSP) mortgages, guarantor mortgages, joint ownership, springboard/offset savings products, equity release, and trusts.
Each option can affect mortgage affordability, tax, and legal ownership, so clear understanding matters.
Why family support is increasingly common
With higher house prices, stricter affordability, and cost‑of‑living pressures, more first time buyers rely on family help. Government schemes (like the Lifetime ISA or shared ownership) assist, but often don’t close the gap in higher‑value markets.
1) Gifted deposits
Gifted deposits remain the most common way families help.
Key points:
- Lenders require a gift letter confirming the funds are a gift, not a loan.
- For IHT, most gifts are potentially exempt transfers and usually fall outside the donor’s estate after 7 years. Consult your tax advisor though.
- Consider how gifts interact with nil‑rate bands, taper relief, and the donor’s long‑term financial security. Again, consult your tax advisor.
- Manage expectations across siblings to avoid future disputes.
2) Family loans (not gifted deposits)
Family loans can help boost deposits or reduce borrowing needs, but must be documented.
Key points:
- Use a simple loan agreement (amount, term, interest, repayments). This is best drawn up with the expertise of a solicitor.
- Many lenders treat loans as financial commitments, reducing affordability.
- Outstanding loans may remain part of the donor’s estate for IHT. Consult your tax advisor.
3) JBSP (Joint Borrower, Sole Proprietor) mortgages
A popular option when income is the main barrier.
Key points:
- Parents help with affordability without being added to the title.
- Avoids the Stamp Duty / LBTT second‑home surcharge (5% in England, 8% in Scotland).
- Parents are fully liable for the mortgage, which may impact their own borrowing.
4) Guarantor mortgages
A parent guarantees the buyer’s repayments.
Key points:
- Sometimes backed by savings or property.
- If the buyer defaults, the guarantor may face credit impact or legal action.
- Less common than JBSP but useful in the right circumstances.
5) Joint ownership
Parent and child buy together and are both on the title.
Key points:
- Usually triggers the 5% (England) / 8% (Scotland) surcharge if the parent already owns a home.
- May lead to Capital Gains Tax (CGT) when selling.
- Use a declaration of trust to record contributions and protect interests—especially if the buyer has a partner.
6) Family offset & springboard mortgages
Savings‑linked mortgages that allow parents to support without gifting money outright.
Key points:
- Parents deposit savings with the lender to reduce the buyer’s interest rate or deposit requirement.
- Funds are usually locked for a fixed term and may be at risk if repayments are missed.
7) Equity release & later‑life lending
Useful for older homeowners wanting to gift money.
Key points:
- Releases tax‑free capital for gifting.
- Interest can compound quickly, reducing the estate.
- Suitability and long‑term care planning must be assessed carefully.
8) Trusts & family companies
More advanced options for managing family wealth.
Key points:
- Trusts can protect assets and control access but add admin and tax complexity.
- Company structures may help in certain scenarios but affect mortgage options and tax treatment.
Common risks families overlook
- Undermining the donor’s retirement security or future care needs
- Unexpected IHT, CGT, or Stamp Duty / LBTT liabilities. In the majority of these aspects, a tax advisor is worth being consulted to understand your position
- Informal loans with no documentation
- Misunderstanding JBSP or guarantor responsibilities
- Family conflict due to unclear ownership or expectations
