Alicia,being you only need 2 br. there are several apartment homes, on Roswell Rd in Sandy Springs that meet your need, you can just ride down the street and take your pick. It will be difficult to find single family homes at this price point.
I'm sorry, the multiple listing service shows no 2 bedroom rentals in the Sandy Springs area within your price range. Since you are now in Atlanta, I would recommend that you look through the free apartments for rent books found at grocery stores.
