Good Guy Guarantee

A good guy guarantee is a limited personal guarantee in a commercial lease — common in NYC — under which the guarantor is liable for rent only through the date the tenant peacefully surrenders the space.

What it means

The good guy guarantee is largely a New York City creation. It protects the landlord from a tenant who occupies without paying while litigation drags; once the tenant moves out and returns the keys, the guarantor's liability stops.

It is a compromise between full personal guarantee (unattractive to tenants) and no guarantee (unattractive to landlords). Good-guy guarantees are widely used in NYC office and retail.
