About Cobb County

Cobb County anchors Metro Atlanta's northwest side. It runs from the Chattahoochee River up through Marietta, Smyrna, Kennesaw, Acworth, Powder Springs, and Mableton. The county carries a deep job base of its own, and East Cobb has been one of the metro's most competitive submarkets for decades. Access runs on I-75 and I-285. The Battery and Truist Park give Cobb a front porch most suburbs would trade for.

TRG proprietary data

How often do listings fail to sell in Cobb County?

34.4% of Cobb County listings that left the market in the 12 months through September 2026 failed to sell: 4,203 withdrawn or expired against 8,020 closed.

That means about 1 in 3 of those listing attempts ended without a sale, after the prep, the showings, the waiting. Each relisting counts separately, so this measures attempts, not homes. Pricing and the first two weeks have a lot to do with which group a listing lands in, and it's the number listing agents almost never show you.
