Answer:
To mitigate damages
Step-by-step explanation:
When a a tenant breaches the terms of a real estate agreement, the landlord must come in to get another tenant to occupy the space.
He is avoiding a situation where the property is to be left unoccupied for a period of time.
Mitigating damages is a way of reducing further loss when one party breaches a contract.
In the given scenario if a tenant moves out of leased premises before the term of the lease expires, the landlord is required to make a reasonable attempt to lease the property to another party.
