Guarantor Mortgages Belfast
Last Updated: 3rd Febuary 2026
Guarantor mortgages are designed to help people buy a home with the support of a family member, often where affordability or deposit size is the main barrier. Rather than being a solution to poor credit, guarantor mortgages are typically used to bridge an affordability gap and support buyers who are otherwise financially responsible.
At AIMS NI, we provide independent, whole-of-market advice on guarantor mortgages across Northern Ireland. We help both buyers and guarantors fully understand how these mortgages work, ensuring everyone involved is comfortable, informed, and protected.
What Is a Guarantor Mortgage?
A guarantor mortgage is a type of home loan where a family member agrees to support the mortgage application by guaranteeing part, or sometimes all, of the mortgage repayments. This support reduces the lender’s risk and can help the buyer borrow more than they could on their own.
The guarantor does not usually live in the property or appear on the property deeds. Instead, they provide a financial guarantee, giving the lender reassurance that repayments will be met if the borrower is unable to do so.
How Guarantor Mortgages Work in Practice
With a guarantor mortgage, the buyer applies for the mortgage in their own name, while the guarantor agrees to support the application. Both the buyer and the guarantor are assessed by the lender, including income, affordability, and credit history.
The guarantor is only called upon if the buyer fails to keep up with mortgage payments. In many cases, the guarantor’s responsibility is reviewed over time and can be removed once the borrower’s income increases, the mortgage balance reduces, or the property value rises.
AIMS NI ensures both parties understand how the guarantee works and how it can be removed in the future.
Who Are Guarantor Mortgages Designed For?
Guarantor mortgages are commonly used by buyers who have strong income potential but need additional support at the start of their home-buying journey. This often includes first-time buyers who are early in their careers, buyers with limited deposits, or applicants who fall short of affordability on their own.
They can also be suitable for buyers returning to homeownership after renting, or for those purchasing in higher-priced areas where affordability is stretched.
Who Can Be a Guarantor on a Mortgage?
Most guarantors are close family members, such as parents or grandparents. In some cases, other relatives may be considered, depending on the lender.
Guarantors are usually required to have stable income, good credit history, and sufficient affordability to support the guarantee. Lenders also consider the guarantor’s age and any existing financial commitments. AIMS NI assesses guarantor suitability early in the process to avoid issues later on.
What Does a Guarantor Agree To?
By acting as a guarantor, a family member agrees to cover mortgage payments if the buyer is unable to do so. This responsibility can affect the guarantor’s own borrowing ability, as the mortgage may be taken into account when they apply for credit.
It is important that guarantors fully understand the commitment they are making. AIMS NI explains the responsibilities clearly and ensures guarantors receive the right information before proceeding.
Benefits of Guarantor Mortgages for Buyers and Families
Guarantor mortgages can offer several advantages for both buyers and their families. They can increase borrowing potential, reduce the need for a large deposit, and help buyers access more competitive mortgage options.
For families, guarantor mortgages allow support without gifting large sums of money upfront. The structure is often designed to be temporary, with a clear plan for the guarantor to step away in the future.
