South Fulton’s Campbellton Road Corridor: Atlanta’s Rising Investment Hotspot Fueled by Transit Upgrades

The stretch of Campbellton Road in South Fulton is rapidly transforming into one of Atlanta’s most promising growth corridors, buoyed by fresh infrastructure spending and a string of new developments.

After years of slow, scattered interest, the area is seeing a sharp uptick in investor attention this summer following MARTA’s June announcement that construction on the long-anticipated Campbellton Rapid Transit Project will begin before the end of 2026. With the city’s population forecast to top 540,000 by next year, and rising prices squeezing buyers out of popular intown districts, developers have set their sights on this overlooked pocket of southwest Atlanta.

Transit Spurs Renewal — and Opportunity

MARTA’s rapid bus corridor is at the heart of the excitement. The 8.4-mile line will connect Greenbriar Mall to the Oakland City MARTA station, bringing high-frequency service to neighborhoods like Ben Hill, Green Acres Valley, and Fort Valley. “Campbellton Road is getting the kind of reliable transit that changes how people move and where they can afford to live,” said one local planner associated with Invest Atlanta.

Commercial activity is following quickly. The recently completed Greenbriar Marketplace on Headland Drive is already 92% leased, according to property records, while developers with Harrington Realty are pushing ahead with plans for a new mixed-use complex at the corner of Campbellton Road and Childress Drive. At least three multifamily projects have broken ground since March between Delowe and County Line Road. Even the old Campbellton Plaza, once emblematic of the corridor’s long decline, is getting a facelift with new retailers and a planned food hall set to open next spring.

Rising Prices and Local Momentum

According to May figures from the Atlanta Realtors Association, average home prices in South Fulton’s 30331 zip code have jumped 16% year-on-year to $298,000, outpacing citywide growth. Land prices along Campbellton Road have surged, too: one vacant parcel near Welcome All Park recently sold for $2.3 million, nearly triple its 2022 valuation. Locally, the Greenbriar Neighborhood Association recorded more than 25 redevelopment permits filed since January — the highest total for the area in over a decade.

This spike is especially striking compared to other Southwest neighborhoods like Cascade Heights and Adams Park, where prices have plateaued over the past six months. Realtors report growing investor demand for “walkable” sites within a half-mile radius of the forthcoming transit stations. “We’re getting calls from buyers we’ve never worked with before, many from Midtown and Buckhead,” confirmed one agent with Keller Williams Atlanta.

For those considering a move or investment, time may be running short. MARTA says its Campbellton BRT line will debut in late 2027, but property values are moving faster than the bulldozers. Buyers seeking entry-level options are gravitating toward properties south of Hogan Road and older townhomes near Deerwood Academy, some of which are still trading for under $240,000. But veteran local investors warn there’s little inventory left at last year’s prices.

Throughout this corner of southwest Atlanta, new infrastructure is setting off a wave of reinvention, but with it comes mounting competition. Buyers eyeing the Campbellton corridor would be wise to act soon — or risk missing out on one of Atlanta’s last affordable growth hotspots.
