DESCRIPTION: Guarantor mortgages help buyers who can't get a mortgage on their own. But they put the guarantor at real financial risk. Here's what both sides need to understand.
SECTION: What Is a Guarantor Mortgage?
A guarantor mortgage is a home loan where a third party — typically a parent or close family member — agrees to cover the mortgage payments if the borrower cannot. The guarantor doesn't necessarily have to own a property themselves, but they must have sufficient income or assets to cover the debt if required.
Lenders offer guarantor mortgages to borrowers who would otherwise fail affordability checks — usually because their income is too low, their credit history is limited or poor, or their deposit is insufficient. The guarantor's financial position supplements the application and provides the lender with additional security.
SECTION: How Is a Guarantor Mortgage Different From a Joint Mortgage?
A joint mortgage means two or more people are co-borrowers — both names are on the mortgage and on the title deeds. Both people own part of the property.
A guarantor mortgage usually has only one borrower on the title — the person buying the home. The guarantor is legally responsible for the debt but doesn't own any part of the property. This is an important distinction: the guarantor bears financial risk without receiving any ownership stake.
SECTION: What Does the Guarantor Agree To?
When someone becomes a mortgage guarantor, they are agreeing to:
- Make mortgage payments if the borrower misses them
- Allow the lender to pursue them for the full outstanding mortgage if the borrower defaults
- Potentially have a charge placed on their own home as security (depending on the lender's terms)
This is a serious legal and financial commitment, not a formality. If the borrower fails to pay and the guarantor cannot cover the debt either, the lender can pursue both parties, potentially affecting the guarantor's home.
SECTION: Types of Guarantor Arrangement
Different lenders structure guarantor mortgages differently. Some common variations:
Income guarantor: The guarantor's income is used to top up the borrower's affordability assessment. The guarantor's home is not used as security.
Property guarantor: The guarantor secures the borrower's mortgage against equity in their own home. This gives the lender stronger security but puts the guarantor's property at direct risk.
Savings-linked mortgages (sometimes called Family Springboard or Boost mortgages): A relative places savings (typically 10% of the purchase price) in a linked savings account, which is held as security. If the borrower keeps up with payments, the savings are returned after a set period (often 3–5 years) with interest. Barclays, Lloyds, and others offer versions of this product.
SECTION: Risks for the Guarantor
The risks are real and should not be minimised:
- Credit impact: If payments are missed, the guarantor's credit record is affected.
- Mortgage affordability: Being a guarantor may affect the guarantor's own borrowing capacity — lenders will factor in the potential liability.
- Property at risk: Where a guarantor has secured their own home against the borrower's debt, default can put that property at risk of repossession.
- Duration: Guarantor arrangements can run for the entire mortgage term (often 25+ years) unless the borrower can demonstrate they meet affordability criteria on their own, at which point the guarantor can sometimes be released.
SECTION: When Does the Guarantor Get Released?
Most lenders will consider releasing a guarantor from their obligations once the borrower has a track record of payments and their income or loan-to-value has improved sufficiently. Typically this might be after 2–5 years. It's not automatic — the borrower must apply to the lender to have the guarantor removed, and the lender will reassess the mortgage on the borrower's income alone.
SECTION: Alternatives to a Guarantor Mortgage
Before committing to a guarantor arrangement, consider:
- Joint borrower sole proprietor mortgages: The guarantor (e.g. parent) goes on the mortgage but not the title deeds — similar outcome but simpler structure.
- Family deposit contributions: Parents gift or lend a larger deposit, reducing the loan-to-value and improving affordability without the ongoing guarantor liability.
- Longer mortgage terms: A longer term reduces monthly payments and may improve affordability.
SECTION: SimpleMoney Verdict
Guarantor mortgages are a legitimate solution for buyers who can't yet qualify on their own. But both parties need to go in with their eyes open. The guarantor is taking on real financial risk for no ownership benefit. Get independent legal advice before signing — and have an honest conversation about what happens if things go wrong.
