many pilots and airline employees living in Peachtree City. It's a hike from PTC to PDK...but only about 30 minutes south of ATL airport if you'd be based there in future. Very good schools in Fayette county for your wife's future employment.
I think you're looking to rent. There are some good houses in PTC for $1000/1500 a month. I'm trying to sell mine now but if it doesn't....I'll be renting it out.
Check out my blog... has my house details.....but even if it's not for you I've got lots of content on my site regarding Peachtree City as a great place to settle in metro Atlanta
cheers
