I rent a house, and basically rent the rooms out, The Lease and all bills are in my name and my name alone. In short things are not working out with a roommate, He is payed to the end of this month. I am questioning if I want to give him the option to pay for next month to give him time to find a place. Can I tell him he is out at the end of this month? There is nothing on paper between us. I am going to write contracts or roommate agreements for all and any from now on.
