just evict ruin his credit be sure eviction papers state (T'sname) et.al. do this with a lawyer - don't try yourself get eviction ruling and back order of all rent owed (late fees wil not be processed by the court) Do NOT include late fees on eviction (judge will throw the whole thing out and you will have to start over) if damages after they are all evicted; process through courts on another suit destroy his credit and he will learn a valuable lesson on life and responsibility
Deduct the late fee from any money you receive first. That leaves a shortage in the rent. Always deduct the oldest bill owed first. In the future use the LPA lease, the late fees are defined as "added rent."
