1. Don't settle on the first place you see. Have a look around and see what's available.
2. When you're there, ask some of the people that are going in/out what they think of the building. People are usually brutally honest about problems in the building when asked.
3. Check for broadband availability.

4. Have at least a month's worth of reserve money to cover "unexpected" expenses.
5. If you have a problem with the way your roommate is doing something,
talk to him/her about it. Nothing will ever get solved if the other person doesn't know about it.
6. Please don't bitch about your roommate here on ATOT. (unless it's a juicy story

)
