An individual or entity that provides a financial guarantee backing the tenant's lease obligations, agreeing to pay rent and perform other covenants if the tenant fails to do so.
Guarantors provide credit support to landlords when the tenant entity itself lacks sufficient financial strength. In small business leases, guarantors are typically the individual principals of the tenant LLC or corporation. In corporate leases, parent company guaranties are common. Guarantors must sign a separate guaranty document — not simply the lease — to be legally bound. The scope of the guaranty (full-term vs. good-guy vs. limited by dollar or time), the guarantor's financial capacity, and the ease of enforcement against the guarantor are key underwriting considerations. Lease abstracts should identify every guarantor, their relationship to the tenant, and the nature and scope of the guaranty.
