A lease guarantor is a third party who assumes financial responsibility for a lease agreement should the primary tenant default. For example, if a tenant fails to pay rent or damages the property beyond the security deposit, the individual acting as the surety becomes liable for the outstanding costs. This individual provides an additional layer of security for landlords.
This added security reduces the landlord’s risk, making it more likely they will approve applicants with limited credit history, insufficient income, or other factors that might otherwise raise concerns. Historically, requiring a surety has been a common practice for student rentals and individuals relocating to a new city. The presence of a surety can benefit tenants as well, allowing them to secure housing they might not otherwise qualify for.
