Guarantor Mortgage
This is a mortgage where a close family member (parent, grand-parent, aunt/uncle and sibling) agrees to shoulder some of the risk by acting as a guarantor.
This usually means them providing all or part of a deposit as well as using their income in addition to the applicant to help boost their affordability. This helps when the property is otherwise out of reach. A guarantor may also be required if the applicant has a poor or lower credit score.
The downside to a guarantor mortgage could be if the property is repossessed and sold the guarantor may be liable to cover any shortfall.
