If a son, daughter or other family member is struggling to get onto the property ladder, you may be wondering how you can help. While many people are familiar with the 'Bank of Mum and Dad', another option is becoming a mortgage guarantor.

Acting as a guarantor could help a loved one secure a mortgage sooner, but it also involves legal and financial responsibilities that need careful consideration.

Here's what you need to know before committing.

What is a Mortgage Guarantor?

A mortgage guarantor agrees to step in and cover mortgage repayments if the borrower is unable to pay. In doing so, they provide additional security to the lender and help strengthen the mortgage application.

Guarantors are often:

  • Parents
  • Grandparents
  • Close family members
  • Occasionally close friends

The guarantor doesn’t usually own the property and isn’t typically named on the title deeds.

Why Might Someone Need a Guarantor?

A guarantor may help someone who doesn't currently meet a lender's affordability requirements on their own. This often includes first-time buyers with a smaller deposit, a lower income, or limited credit history.

Although traditional guarantor mortgages are less common today, a range of family-assisted mortgage solutions continue to help buyers access the property ladder.

How Does Being a Guarantor Work?

Lenders will assess the guarantor's financial circumstances, including their income, credit history, savings and, in some cases, the equity in their property.

If approved, the guarantor agrees to a legally binding commitment that may remain in place for several years, depending on the lender and mortgage arrangement.

What Are the Benefits?

For buyers, a guarantor arrangement can improve affordability, increase borrowing potential and make homeownership possible sooner.

For family members, it offers a way to provide meaningful support without necessarily gifting a large sum of money upfront.

What Are the Risks?

Helping a loved one buy a home can be incredibly rewarding. However, becoming a guarantor is more than a gesture of support. It's a legally binding commitment that could affect your finances if things don't go according to plan.

You Could Become Responsible for the Mortgage

If the borrower cannot make repayments, the lender may require the guarantor to step in. This could affect your own financial position and future borrowing ability.

Your Home or Savings Could be at Risk

Depending on the arrangement, savings or equity in your property may be used as security. Understanding the lender's terms is essential before agreeing to become a guarantor.

It Can Affect Future Borrowing

Acting as a guarantor may affect your ability to take on additional borrowing in the future, as lenders may factor the commitment into affordability assessments.

Family Relationships Can Become Strained

As with any financial arrangement involving family, it's important to have clear conversations about responsibilities and expectations from the outset.

Questions to Ask Before Becoming a Guarantor

Before agreeing to support someone's mortgage application, consider the following:

  • Could I comfortably afford the repayments if required?
  • How long could my commitment last?
  • Will this affect my own financial plans or borrowing?
  • Have I taken independent legal advice?

A guarantor arrangement should never be viewed as a formality. It is a legally binding financial commitment.

Are There Alternatives?

Depending on the circumstances, alternatives may include family-assisted mortgage products, Joint Borrower Sole Proprietor (JBSP) arrangements, gifted deposits or other mortgage options designed to support first-time buyers. A mortgage adviser can help identify the most suitable approach.
