We got a lot of cosigner guarantors because a) we asked for them, and b) because they added backup to the applicant’s promise to fulfill the terms of the lease. We found collecting from the cosigner after move out was often easier than collecting from the tenant who left owing a balance. Often we got an employer, parent, sweetheart, partner or relative to back the applicant and agree that if they left owing money, the co-signer would make good on their promise. It’s amazing how a threatening letter or two wakes them up and they pay the bill left behind by the tenant. Owners are grateful when you do a great job for them and are pleased when they see you go the extra mile to protect them.
