Co-Signer or Guarantor
What is a lease guarantor?
A guarantor is a person who will co-sign an apartment lease alongside a tenant, guaranteeing to pay the rent if the tenant fails to do so. The guarantor is usually a parent, family member, or close friend who is willing to be legally responsible for the rental apartment.
In the context of renting apartments, the terms guarantor and co-signer are sometimes used interchangeably. Both guarantors and co-signers are responsible for paying the rent if it goes unpaid by the tenants.
