(I want to keep my Facebook account private so I'm posting my ROV comment here instead. Thanks for understanding!) __________________ I think this is actually a pretty common thing – some guy who say's he's a student (but weirdly can't produce any student ID) moves into a house full of students and, after a short period of time, stops paying rent, stops doing chores, starts acting all creepy and inappropriate, etc. These parasites are freeloaders who prey on young folks who are, for the most part, living outside of their parent's home for the first time. Take some advice from someone who's been there themselves! If you're going to rent a room to someone that you can't personally vouch for, you need to take some steps to protect yourself and your other roommates. First, ask to see – and get a photocopy of – their current, valid student ID. Then create a "sublet lease" that clearly states the terms of their rental agreement including move-in date, move-out date, amount of rent and utilities per month (or week), pay half a month's rent up front as a security deposit to be returned to them – with interest – at the end of their lease period (assuming that their rent/utilities are paid up and that their room is clean and in good repair), etc. Include a paragraph that states that they understand that this is a legal contract and that you will sue them in small claims court if the terms of the lease are violated – otherwise, you and your other roommates could be on the hook for their rent and their portion of the utilities, which can add up fast. The prospective renter should sign the 'sublet lease' and you (or whoever holds the lease on the property) should sign it as well in front of them. Provide them with a copy and keep one for yourself in a safe, off-site location. If they argue or have an issue with any of these conditions, tell them to find housing elsewhere. This will keep the freeloading parasites who seek out and prey on young university students out of your home!
