Sell Your Land in Cobb County, Georgia

Most Georgia counties have one origin story. Cobb County has two.

The first came in 1832, when the state carved Cobb out of disputed Cherokee territory and handed it out by lottery to settlers. The second came a century later, when Lockheed Martin’s aircraft plant turned a quiet railroad and farming county into one of the Southeast’s industrial anchors — a transformation so complete that Cobb is now Georgia’s third most populous county, built almost entirely on reinvention rather than sprawl.

That pattern hasn’t stopped. In 2023, Cobb got its newest city in over a century — and it’s already the largest one in the county. Here’s what makes Cobb different, city by city, plus where to go for official property and tax records if you own something here.

From Cherokee Land Lottery to Lockheed: A Short History

Cobb was the 81st county established in Georgia, named for U.S. Senator and judge Thomas Willis Cobb — not for the crop, despite what a lot of longtime residents assume. Marietta, its county seat, was likely named for Cobb’s wife, Mary, and was chartered in 1834 in the geographic center of the new county.

Before the Civil War, Marietta had a strange second identity: a summer resort town. Wealthy families from the Georgia and Carolina coasts came inland to escape yellow fever season, filling hotels and a sanitarium built specifically to cater to them. That era ended abruptly in 1864, when Union forces occupied the town during the Atlanta Campaign — the Battle of Kennesaw Mountain, fought in the county’s north end, remains one of the most-visited Civil War battlefields in the country.

The county’s modern identity was set in 1942, when Bell Aircraft Corporation built a massive manufacturing plant in Marietta. Lockheed took it over in 1951 and still builds aircraft there today. That single decision pulled Cobb from a farming county into an aerospace and manufacturing hub — a shift you can still see in the county’s employer list, now led by WellStar Health System, Lockheed Martin Aeronautics, and Cobb County Schools.

Six Cities, Plus the One That Just Overtook Them All

CityWhat It’s Known For
Marietta (county seat)The original center of the county — Civil War history, a historic downtown square, and the Marietta National Cemetery
SmyrnaDense, walkable redevelopment near the Battery Atlanta and Truist Park, home of the Atlanta Braves since 2017
KennesawAnchored by Kennesaw State University and named for the nearby Civil War battlefield; formerly the rail stop known as “Big Shanty”
AcworthA lakeside community on Lake Acworth and Allatoona, popular for its small-town downtown and outdoor recreation
Powder SpringsOriginally “Springville,” renamed for its mineral springs; a quieter, more residential character than its neighbors
AustellCobb’s smallest incorporated city, best known as the home of Six Flags Over Georgia
Mableton (newest)Incorporated in 2023 after a narrow voter referendum — and immediately became Cobb’s largest city by population, absorbing parts of unincorporated Austell and Smyrna along the way

That last line is worth sitting with: Mableton didn’t exist as a city until 2023, and it’s already outsized Marietta, the county seat that’s been around since 1834. It’s a rare, almost unheard-of shift in a metro area where most city boundaries have been fixed for generations.

Cobb County by the Numbers

  • Population: roughly 793,000 (2025 estimate) — Georgia’s 3rd most populous county, behind only Fulton and Gwinnett
  • Land area: 340 square miles
  • Education: the U.S. Census Bureau ranks Cobb as the most-educated county in Georgia, and 12th nationwide
  • Affordability: consistently listed among the top 20 most affordable large metro areas in the country
  • Colleges and universities: seven, including Kennesaw State University, the second-largest university in the state by enrollment

Where Fulton’s story is dominated by Atlanta’s downtown core and DeKalb’s is defined by its cultural diversity, Cobb’s identity is really an economic one — a county that reinvented its entire employment base once already (farming to aerospace) and is now reinventing its map of cities in real time.

Selling a Property in Cobb County

Between six long-established cities and one that’s rewriting the county’s population map in real time, Cobb covers a lot of different situations — a rental you inherited in Marietta, vacant land near Acworth, a house in Mableton that needs more work than you want to take on.

If back taxes are part of the picture, our tax-delinquent property guide covers how a direct sale can settle the balance at closing instead of dragging into a county tax sale. Property that’s sat vacant or unused for a while has its own considerations, which we break down on our vacant land page. And if what you’re holding needs repairs before it could ever be listed, see how we evaluate houses sold as-is, no renovations required on your end.
