Cash for keys? How to draft offical documents

[THANG BUI]

So I'm dealing with a nightmare situation right now with my tenant. She cannot afford the place and subletted to 3 other people. One of those people is causing problems and I want to remove him. Unfortunately he wont leave. I tried to get the tenant to hire a lawyer to evict but she cannot afford.

This leaves me with two options, evict the whole unit. Or offer cash for keys. I was going to offer his monthly rent of $300 to have him leave by the end of the month. I will change out the locks but I heard he has a tendency of re-entering through the windows.

Is it possible for me to draft a document that he signs stating that he no longer lives there? I want to make sure that after I pay him $300 when he leaves that he will not re-enter the place.
