Is a room to rent possible? I know I saw some fabulous deals on craigslist over the weekend for some really nice places to live for that price (with utilities included!)
Otherwise, I would hit up
www.apartmentratings.com
At least that way, you can get some honest reviews from actual residents. With that range, you're best bet would probably be some of the older apartment complexes. Try Six Forks Station or do a search under apartment ratings for zip code 27612.
Good luck!
