A little late, but my post is in comparison to Cleveland, OH where for the same prices you could get something much nicer. I would also have many more living options available in Cleveland proper compared to the few areas in Detroit proper worth living.
I will say that if you are moving away from a coastal area then Detroit is pretty cheap and has some interesting things to offer. However, being from Cleveland I can enjoy the positives of Detroit with a 2 hour drive without having to live there.
