Well if you're scared of black people in general, as our friend Mr. Smith appears to be, Atlanta may just not be for you. If you're dead set on living in a white flight neighborhood (Alpharetta, Dunwoody, Sandy Springs, Gwinnett, Cobb, most of the North suburbs) you're gonna get stuck with bad traffic.
Let me tell you, if living in the "nice" part of town made Mr. Smith hate Atlanta so much, what's so nice about it? I live in a great neighborhood in the city, have lived in Atlanta for 20 years or so and have lived in several intown neighboroods. Midtown, Virginia Highlands, Morningside, Decatur, Druid Hills, these are the nice neighborhoods in the city.
As I said, you're going to pay a lot more in the city for the same house in the north suburbs, but you're going to avoid the traffic (assuming you're working intown). Not to mention the fact that I'm not comfortable living with a bunch of whitebred southern baptists out in Cobb county, I don't particularly MIND that the metro area is ~70% black. The culture is here. If you live in most of the North suburbs the most culture you're gonna get is TGI Friday's.
There are neighborhoods around here where you can get a decent house for $350k but it's not gonna be nearly as big as something outside the city. Spend $350k in Alpharetta and you get a 3000ft2 McMansion, which some people love, but if you spend $350k intown you're gonna get 2-3 bedrooms of a house with some character from the mid-early 20th century. Check out Inman Park, Edgewood, etc, these are the up and coming neighborhoods intown where you can get a house now for $300k that's gonna be worth $500k in 10-15 years.
