I'm a single woman whose moving from Miami to Atlanta advice on what area to live,areas/places to avoid?

Living close to work is a big plus in Atlanta. But only if work is in a desirable neighborhood. Also living close to the train is a good idea if the train will get you to work. The best suburban areas are all north or downtown Atlanta. Avoid southwest Atlanta, anything on the west end and almost every county south of downtown. If you want to live downtown look at Midtown first, then Buckhead, then Brookhaven, Ponce Highland and some of the neighborhoods north and east of downtown. If you prefer suburban life check out Marietta, Sandy Springs, Dunwoody. Further out is Alpharetta, Roswell, Johns Creek and Cumming but being a single woman I'm not sure you would want to live 40 miles outside the city. Cobb County, North Fulton, Gwinette and South Forsyth (way north) is where you want to concentrate your efforts on.

Be careful. You can find an AWESOME apartment right next door to the ghetto. I loved living in Virginia Highland area at Gables Rock Springs and I lived in the Perimeter area at Post Dunwoody. Those were both great when I lived there (it was about 5 years ago though). But if you call a police station and ask about an apartment complex they will tell you the crimes that have occurred there and about the area around it.
