I'm in GA but I'm up here next to NC.
There's plenty of good riding in N GA. Check out the gartra site. TWO in suches has a site. KLR650.net has an active ride thread. Dixie Dualsport is good also. ADV's, southeast regional forum has a georgia thread that is very active.
I don't know much about the Marrietta area. You may be able to rent a small house for around the same price or look up a deal on a bank owned property and buy. I wouldn't want to commute very far in the traffic. I know a guy with some rental houses around Canton area. He may have something available.
You don't have to travel too far from Marrietta to be in the country again.
Good luck on the job.
