if you don't mind driving a little bit then you might be able to find some good deal in canton or belleville.
You can definitely find some decent rooms for rent in houses. The problem is that I feel like this arrangement could be more hit/miss than an Apartment complex, but that's just my opinion.
I used to live around the corner from this business (but have never used them):Relocation Central - Apartment Search734-677-3710www.relocationcentral.comIts suppose to be a free service, so you've got nothing to lose. You won't find anything decent for under $800. I used to pay around $635 in the Ypsi ghetto about five years ago. Then I moved to nice ones in Ann Arbor for just under a grand. Now I'm in Milan, about 12 miles south of Ann Arbor. Nice area, very laid back and quiet, and cheap. Its right off the main highway (23) that Ave Marie is off of. I would suggest trying there. It only takes about 25 minutes tops to go from my condo to Ave Marie.
