I live in Vinings, near the border of Vinings and Buckhead. Apartments are nice, but if you're going to be here a while, the market's tanking and bottom is a few months out still. Might want to invest in that house your woman is looking at. Make a lowball offer. It's a buyer's market.
Peachtree City and Newnan are nice cities, but really boring. Good if you have kids and stuff. Nice conservative type towns.
Vinings, Smyrna, and the suburban part of Buckhead are a great mix of suburban and cosmopolitan. Lots of great restaurants and stuff.
Best of luck.
