When applying for a rental property, landlords may request additional financial backing to reduce risk—especially if the tenant has limited credit history, low income, or is a student. In these cases, two common options are a co-signer or a guarantor. While these roles are sometimes used interchangeably, they have distinct responsibilities and implications. Understanding the difference can help both tenants and landlords make informed decisions.
What is a Co-Signer?
A co-signer is someone who signs the lease agreement alongside the tenant and agrees to be equally responsible for all the terms of the lease. This includes paying rent, covering any damages, and complying with the rules of the tenancy. Importantly, a co-signer typically has the legal right to live in the rental unit, although they may choose not to exercise that right.
Because co-signers are legally considered tenants, they assume all the rights and obligations that come with the lease. This makes co-signers ideal for situations where the additional party is not just a financial backup, but also potentially a resident.
What is a Guarantor?
A guarantor, on the other hand, provides a safety net without being part of the lease agreement itself. Instead, they sign a separate guarantee agreement, which outlines specific responsibilities—most commonly, ensuring rent is paid if the tenant fails to do so.
Guarantors do not have the right to live in the rental unit and are only held liable if the tenant defaults. Their role is more limited in scope, focused purely on financial assurance rather than tenancy rights.
How to Choose Between a Co-Signer and a Guarantor
The choice between a co-signer and a guarantor depends on the situation:
-
Use a co-signer when the additional person is willing to take on full legal responsibility and potentially live in the property.
-
Use a guarantor when the goal is simply to add a layer of financial security, with no intention for the guarantor to reside in the unit.
From a landlord’s perspective, a co-signer might offer more comprehensive protection since they are fully liable and easier to pursue legally under the lease. However, some landlords prefer guarantors, especially in student or newcomer scenarios, where parents or relatives want to support the tenant without becoming a party to the lease.
