Mortgage options for parents who want to help first-time buyers

High house prices, tough affordability checks and the need to save a large deposit can make it hard for first-time buyers to get a mortgage and buy their first flat or house.

If you want to help your child buy a home but don't have enough savings to simply give or lend them the cash, there are several options you can consider.

Guarantor mortgages

With guarantor mortgages, the amount your child can borrow is based on your income and assets, as well as theirs.

You’d be guaranteeing to meet any repayments that your child failed to pay, which could be risky, especially if you still have a mortgage on your own home.

Joint mortgages

A joint mortgage considers both your and your child’s income, as well as any money outstanding on your own mortgage.

Both you and your child will be named on the mortgage agreement and on the deeds, providing you with some power over any future transactions. But you would also be liable for keeping up the mortgage repayments and, if you already own a property, you'll probably have to pay the second home stamp duty surcharge.

Joint borrower sole proprietor mortgages

With a joint borrower sole proprietor (JBSP) mortgage, much like a regular joint mortgage, the lender assesses both your and your child's financial circumstances when deciding whether and how much to lend.

The key difference is that only your child is named on the property deeds, meaning they alone own the property.

Both you and your child are responsible for the mortgage repayments.

What are the benefits of a joint borrower sole proprietor mortgage?

  • Your child may be able to borrow a larger amount than if they were applying on their own
  • Unlike a guarantor mortgage, a JBSP mortgage won't require you to put up additional security, such as your home or savings, to guarantee the loan
  • As you won't own any share of the property, you won't have to pay the second home stamp duty surcharge

JBSP mortgage eligibility

If your child can show that their salary is likely to increase in the future, a lender may be more likely to approve your application.

Lenders also take the age of the parent into account, considering how old you'll be by the end of the mortgage term.

If you have a mortgage on your own property, one option is to free up some cash by remortgaging. This would involve arranging a new mortgage with your existing provider or transferring to another lender.

Your mortgage term could be increased to absorb the additional borrowing, your repayments could rise, or both. 

A further advance from your existing lender is another form of loan you could get that would be secured on your home.

Before remortgaging it’s important to consider the impact that increased borrowing would have on your own standard of living and your retirement plans.

The Bank of Mum and Dad and inheritance tax

If you're going to give money to your child, you'll need to understand the taxation rules around gifting - as parents handing out large lump sums could face a hefty inheritance tax (IHT) bill. 

You're allowed to give away up to £3,000 a year without it counting towards IHT - and you can backdate this by a year too, so in theory a couple could give away £12,000 in a tax year if they haven't gifted anything the previous year. Separate individual gifts of up to £250 are also allowed.

On top of this, it's possible in some cases to draw on unused income to make regular gifts if doing so doesn't affect your standard of living. 

Outside of these exclusions, your child might need to pay inheritance tax on any gifts given to them if you die with seven years - though this depends on their cumulative value. To find out more, read our full guide on inheritance tax planning and tax-free gifts.

Bank of Mum and Dad: 10 tips for parents helping first-time buyers

If you decide to help your child buy a home, it’s likely you'll want to maintain an element of control, if only to ensure your money isn’t wasted. 

Here are 10 tips for parents who want to help their child buy their first property without causing any conflict or severe financial difficulties.

1. Speak to an expert

If you can't afford to buy a house or flat outright, it's likely you'll want to help your child find the best-possible mortgage deal. 

  • Which? Mortgage Advisers looks at every available mortgage from every available lender and will give you and your child impartial advice on the best type of mortgage for their individual circumstances. You can call the team on 0800 197 8461 for free and even set up a group appointment. 

2. Update your will accordingly

If you do buy an official share in the property, don’t forget to update your will to reflect what you’d like to happen to it upon your death. Our will-writing guide explains how to validate, store and update your will. 

3. Understand your tax liabilities

If you are named on the deeds, you may be liable for certain taxes associated with the property. Read our guides to tax on property and inheritance tax for information on your potential tax liabilities. 

4. Be clear about how things will work

You need to make your child aware of whether you are making a gift, a loan (with or without interest) or an investment. It might be an awkward conversation, but it will make things much easier in the long run.

5. Communicate

If your child feels embarrassed or guilty about accepting money from you, this could make them less likely to tell you if they’re worried about meeting their monthly repayments. Encourage an open dialogue and tell them that they can always come to you if they get into difficulties.

6. Make it legal

Get a legally binding agreement drawn up by a solicitor. To safeguard a loan or investment, make sure it stipulates the nature of any arrangement.

7. Formalise things with the Land Registry

Even with a legal agreement in place, your child could potentially sell the property without your consent. If you're concerned about this and want to avoid it happening, complete Land Registry form RX1.

8. Discuss home improvements

If you’re buying jointly, make sure you talk about the home improvements you think the property could benefit from – your ideas might be very different from your child’s, so it’s worth having this conversation early on.

9. Be honest with the mortgage lender

It's essential to be honest about your financial circumstances. Don’t exaggerate your income to secure a larger mortgage.

10. Consider future rate rises

Don’t put yourself in a financially risky predicament by overextending yourself, and don’t assume that mortgage interest rates will remain at the same level.

Recent base rate rises have shown this is unlikely - use our mortgage repayment calculator to see how different interest rates would affect your monthly payments.
