Marlboro County, South Carolina
Marlboro County sits in the Pee Dee region of northeastern South Carolina on the North Carolina line, anchored by the county seat Bennettsville and small mill towns including McColl and Clio. The market is dominated by row-crop agriculture and a handful of manufacturers, land values are low, and population has declined slightly since 2020, so activity centers on farmland, timberland, and existing housing stock rather than new subdivisions.
