What is a family offset mortgage?

A family offset mortgage is a special class of offset mortgage  that can be used to help family members get on to the housing ladder. Sometimes called a  ‘parent offset mortgage’, it is most commonly used by parents who want to help their children with a purchase, but the recipient can occasionally be any nominated family member.

As with a standard offset mortgage, this is achieved by linking a savings account to a mortgage , which has the effect of ‘offsetting’ the loan: in other words reducing the amount of interest due on it.

The main difference is that the mortgage in this case is held not by the owner of the savings account, but by their child(ren) or other nominated family member.

NB: for ease of reference, we will use the classic example of a parent and child taking out a family offset mortgage for the rest of this article.

How does a family offset mortgage work?

In a family offset mortgage, the total amount borrowed is reduced by the value of the parents’ savings. This has the effect of lowering the loan to value ratio (LTV) so that the overall debt is smaller, and interest rates are lower, which in turn reduces the cost of the repayments.

For example, if a mortgage of £300,000 is needed for the purchase and the parents have £50,000 in savings, linking the mortgage account to these savings will reduce the amount being borrowed to £250,000.

The same effect can of course be achieved by putting down a deposit of equal value, but with a family offset mortgage the savings money is returned in full to the parents, once the child has paid off an agreed proportion of their mortgage, usually 25-30%, and it might even accrue interest during the mortgage term.

What are the benefits of a family offset mortgage?

These flexible family mortgages can be a great solution for both parties involved, providing a leg-up onto the property ladder that avoids the often prohibitive outlay of a deposit for the children – while also reducing repayments by allowing access to the favourable interest rates associated with lower loan to value (LTV) ratios.

While the advantages to the children are obvious, parents benefit from being able to help them with the significant upfront costs of purchasing a home without having to give money away permanently. Instead they transfer existing savings to the linked account, knowing that they will get it back once the child is in a position to ‘take over’ the mortgage completely, and they might even earn interest during this period.

Who is eligible for a family offset mortgage?

As long as the applicant can prove they are able to afford the repayments, each lender has its own policies on who they will accept as a borrower: generally the ‘riskier’ the borrower is perceived to be (due to any bad credit issues or buying a non-standard property for example), the smaller the pool of lenders willing to lend will be, which can make it harder to access more favourable interest rates and products with smaller deposits. But in the special case of family offset mortgages there are a few additional details to consider.

First, there is the issue of who counts as a family member, and even if non-family members can benefit.

For example, family offset mortgages with Barclays or Nationwide does not include friends, neighbours or anyone else who is not a legal relative (this definition usually includes step-children, grandchildren, parents, civil partners, spouses, brothers and sisters and more), while one or two lenders can allow customers to link savings accounts to a friend’s mortgage.

Secondly, there is the question of the amount of savings required to help a family member with their mortgage, which we cover in the next section.

How much do you need in savings for a family offset mortgage?

This will depend on the value of the property being purchased, and is usually about 10% of that figure. For example, if the property is valued at £200k, the parents need at least £20,000 in their savings account.

In some cases the provider may stipulate that the parents need to have a certain amount held in savings regardless of the value of the property.

For example, at some high street lenders, customers usually need to have at least £50,000 in savings in a specified bank account, or an annual income of £75,000 or higher.
