I am quite late to the race on this answer, but perhaps you are still looking. Listen to Scott Eaves! Close to the airport (within 3 miles) and still be in a nice historic neighborhood AND you can take MARTA to the airport if you live in the Tri-Cities area: East Point, College Park, Hapeville. (though Hapeville is not on MARTA to ariport). Public schools are a downer, but there are some nice private schools that are not expensive and strong progress on a charter school.
These cities are also closer to Atlanta than the others suggested. They have the intown vibe if you are not looking for suburbia. College Park has a lovely golf course too. Nice sized yards, a real sense of community, and located in Fulton Co. Taxes are reasonable.
Again, if interested - Scott Eaves or I would be happy to give you the tour and represent you.
