Remortgaging to Help Your Child Buy a Home

With house prices making it harder than ever for first-time buyers, many parents consider remortgaging to help their children onto the property ladder. Here are the options and what to think about before committing.

Gifting a Deposit Through Remortgaging

The most straightforward approach is to remortgage your home to raise a lump sum and gift it to your child as a deposit. This is a gifted deposit, and lenders will need a signed letter confirming the money is a genuine gift with no expectation of repayment and no stake in the property.

The advantage is simplicity: your child applies for their own mortgage in the normal way, and the gift simply helps them meet the deposit requirement. Most lenders accept gifted deposits from immediate family members without any issues.

How Much Would You Need to Raise?

The amount depends on the property your child wants to buy and how much deposit they need. A 10% deposit on a £250,000 home would be £25,000, while a 15% deposit would be £37,500. Larger deposits help your child access better mortgage rates, potentially saving them thousands over the life of their loan.

You'll need enough equity in your own home to raise this amount while keeping your LTV within your lender's limits. Remember that increasing your mortgage also increases your monthly repayments, so you need to be comfortable with the higher costs for years to come.

Alternatives to Gifting a Deposit

If remortgaging for a large lump sum isn't feasible, there are other ways to help:

Tax and Legal Considerations

A gifted deposit is treated as a potentially exempt transfer for inheritance tax (IHT) purposes. If you survive seven years after making the gift, it falls outside your estate entirely. If you pass away within seven years, taper relief may reduce any IHT liability. The current IHT nil-rate band is £325,000 per person.

If you're lending the money rather than gifting it, this complicates your child's mortgage application because lenders treat it as a debt your child must repay. Most lenders strongly prefer genuine gifts with no strings attached. It's worth taking legal and tax advice before making large financial gifts to family members.

Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.

Frequently Asked Questions

Yes. Lenders require full disclosure of where the deposit comes from as part of their anti-money-laundering checks. You'll need to sign a gifted deposit letter confirming the money is a gift, not a loan, and that you have no interest in the property. This is standard practice and nothing to worry about.

Increasing your mortgage to help your child reduces your equity and increases your monthly costs. Consider carefully whether you can afford higher repayments, especially as you approach retirement when your income may fall. It's important to ensure your own financial security isn't compromised, however much you want to help.

There's no legal limit on how much you can gift, but larger gifts have more significant inheritance tax implications. Gifts over the annual £3,000 IHT exemption become potentially exempt transfers. If you have a large estate, speak to a tax adviser about the most efficient way to help your child financially.
