FOr that price range, you can move to most areas of Charlotte and be in good shape.
If you have the opportunity, I would come out here before relocating and take a look around and see what each area offers. South Charlotte is not a bad option. I lived in Raintree for years and went to school while there. Looking back, there are definately worse places to be.
I'm sure there will be many people who can tell you more about that area than I can since I haven't lived in that area in amost 10 years.
