I moved to Atl in june. I'm renting for now looking to buy within the next year or so.
I also work right near the perimeter mall, right across the highway
300k should be good for a nice house outside the perimeter, inside the prices go up dramatically!
I'm living in Norcross for the time being and nearby Doraville has a pretty strong Asian feel. I think it is more Chinese and Korean though, can't say I've seen too many filipino stores/restaurants.
Hopefully some of the more seasoned locals can give you more info and welcome to ATL.
