A guarantor must fill out an application, provide income documentation, have their credit pulled, and sign your lease. 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.When requested, applicants can enter other co-applicants, co-signers, and guarantors they'll be applying with on their rental application. The guarantor will be required to complete an application and pay a full application fee. As a rule, I would not recommend having a guarantor on a lease agreement. A lease guarantor form is an agreement that makes a guarantor responsible for a tenant's actions. Fill out the lease guaranty application online and send us your paperwork.
