Cobb County, Georgia
Cobb County anchors metro Atlanta's northwest side, from historic Marietta and the Lockheed Martin plant at Dobbins Air Reserve Base to the Cumberland/Galleria office corridor and Truist Park, home of the Atlanta Braves since 2017. A deep corporate base — Home Depot and WellStar are both headquartered here — keeps demand strong across a county that's largely built out, so redevelopment drives more activity than new ground.
