N. Atlanta Housing Suggestions

I am a 50+ professional (worker, not athlete!) moving back to Atlanta after selling my house in Roswell three years ago.  I am looking for a place to live in the Roswell/Alpharetta/E.Cobb area so that I will be convenient to my office and also my favorite training spots (RAP, Columns, Greenway).
I am using the usual sources such as Craig's List and the AJC, but I was wondering if anyone knew of a condo to rent or a house sharing arrangement with someone who understands a triathlete's weird schedule.  Feel free to email me privately if you prefer: [email protected].
