I have a friend of a friend who has been paying me to stay in a room at my house for two nights a week (pays once a month). He uses my room (his futon is the only possession he keeps at the house). Under our verbal agreement, I have full access to the room when he's not there. (he's only there maybe 20 hours per week... 2 nights to sleep. He uses my bathroom, but does not use the kitchen or any other part of the house and has no clothes or food. This has been informal and we have never discussed a lease or had a deposit. I decided that I no longer wanted to let him stay there because I have friend that wants to stay there full time. When I told him of this development and asked that he move his futon out within the next month or so, he acted irrationally... ran out of the house saying he couldn't talk about this, then avoided me/ and would not return my phone calls or emails for 6 days. I am a woman and this reaction frightened me. I'm afraid he's going to go postal or something. Now I don't want to let him stay there because of this weird reaction. He does not want to leave, but said he would in 6 weeks. Do I have to let him stay there for 30 days?

He is a renter, whether it is in writing or not, you have a contract since you have accepted his money. It is standard to give a renter 30 days notice to vacate in writing. I would suggest you do that.

As Ruby indicated, you have a verbal month to month lease. How much notice you need to give him depends on local laws. Generally, the notice is one full rental period. Not knowing the circumstances, I can't speak exactly to his reaction. But I would imagine it would be hard to find a rental for 2 nights a week and I don't blame him for being somewhat upset.

Definetely put it in writing! Give him a written notice that he has 30 days to remove himself from the property. Make sure you outline specifics in the notice. You may want to find out where he gets his mail so you can send it to him certified, therefore you will have a record that he received it. Good luck.
