It’s not easy to get onto the property ladder these days, but there are products that are designed to make life easier for first-time buyers, especially those lucky enough to have a family willing to help out. Offset mortgages help use savings to reduce the amount of interest you pay on your mortgage.
However, did you know they can even be used by those without any savings of their own? We look at family offset mortgages, how parents can use them to help their kids buy their first home, and how to find the right family offset deal for your needs.
What is a family offset mortgage?
Family offset mortgages allow your relatives to use their savings to reduce your mortgage interest. They work similarly to any other offset mortgage in that a savings account is linked to the mortgage to offset the interest payable. Some lenders allow as much as 100% of the mortgage interest to be offset, meaning the borrower would not have to pay any interest on their loan. They can also be used in lieu of a deposit, depending on lender criteria.
How they differ from a standard offset mortgage is that family members can offset savings, or in some cases, put a charge on their home, against a relative's mortgage. However, the majority of benefactors are parents, so it’s sometimes known as a ‘parent offset mortgage’.
This provides a valuable way to help loved ones get a step onto the property ladder, without the commitment of becoming a traditional guarantor, or giving away a large sum of cash as a gifted deposit. In fact, some lenders allow the held funds to be used in lieu of a deposit, however, in this case it would not be accessible until a certain criteria is met by the borrower.
Particularly useful to first-time buyers or those on a limited income, with a family offset mortgage, as many as six savings accounts (depending on the specific deal criteria) can be linked to one mortgage. The money usually remains accessible to the account owners, and can be withdrawn if necessary. However, in some cases the savings are ‘locked’ by the lenders until the mortgage holder(s) have reduced their LTV (loan to value) ratio to an agreed level. Following this period they are able to withdraw their savings as required.
How do they work?
When family members link their accounts to a loved one’s offset mortgage account, any balance held as savings reduces the mortgage balance by an equal level for interest calculation. For example:
Mortgage borrower takes out a mortgage of £300,000:
Their parents link 2 savings accounts with a total balance of £50,000 to the mortgage
Their uncle links a savings account with a balance of £25,000 to the mortgage
The total savings balance linked to the mortgage is £75,000
When the mortgage interest is calculated:
Rather than paying interest on the full £300,000 that they owe
The mortgage borrower will only pay interest on (£300,000 minus £75,000) so £275,000
On a typical 25 year mortgage of £300 with an interest rate of 5% this would equate to a saving of around £429 per month in interest. Which is £131,700 over the mortgage term.
Of course, the savings held in the linked account can be either reduced or topped up at any time, meaning the interest savings would change accordingly. However, any unused savings could make a real difference to the mortgage holder, allowing them to repay their mortgage more quickly or simply with more affordable repayments.
It’s important to note that any savings held in accounts linked to an offset mortgage will not accrue any interest, as this is being used to offset the mortgage holder's interest.

FAQs
The biggest benefit can be helping your loved ones get onto the property ladder, a fate which is becoming particularly elusive to this generation of homebuyers. However, for those high-earners and high-net-worth individuals, it can also have a tax advantage. While you won’t earn interest on the savings held in a family offset account, you also won’t pay tax on that element of your savings, which could potentially reduce your tax bill for a few years while you help out.
