It is frequently desirable to include in a lease provisions to the effect that if a tenant is dispossessed by summary proceedings, or if the tenant abandons the property and the landlord re-enters and takes possession, the landlord has the option of holding the tenant liable for the rent until the end of the term of the lease. The landlord may re-let the premises as the agent of the tenant, and in such event he credits the tenant with the amount he collects from the person to whom the property is re-let. A clause of this kind prevents absolute termination of the lease by a summary proceeding or the landlord's re-entry.
