My roommate hasn't paid January or February rent. Since he is not in the lease, it has fallen to me to pay all of it. I want him out but the problem is he is never home. I've tried calling him and texting him but his phone is shut off it seems. I've emailed him twice and no response. I do not want him to have access to my things anymore and want to change the locks. How do I proceed? I've put a written dated notice on the door but he hasn't been home.
