I'm not sure on the apartment complexes themselves, but I'm sure you can find decent apartments starting around $400-$450 per month, depending on what you're looking for.
Depending on your budget and how much room you need, I'd go for something like this:

or this:

as opposed to apartment complexes. You can certainly find houses cheaper than that too. Maybe they don't have as much upside as these two, but you won't be hemmed in on 2 or 3 sides by neighbors that may or may not be the type of people you might want to choose to live next to. Of course, this is just my personal opinion, I'm sure many others prefer a complex to a house. As far as the complexes go, I'm not too familiar with ones that would be considered 'good'. I know that there are a couple in the north end to check out. One would be located on Gratiot, north of Krafft (in between Gratiot and Fairway Dr.), another would be on North River Rd. that backs up to the Black River.
I know one of these is called 'Golfview Arms', but I can't remember which one, since they're both close to golf courses.
Good luck in your search.
