Union County, South Carolina
Union County is a small Upstate county centered on the city of Union, built in the late 1800s around cotton-mill villages like Buffalo, Lockhart, and Jonesville. Its textile economy collapsed by the 1990s, and the county's real estate market today is defined by low-cost former mill housing stock and slow, uneven redevelopment rather than new growth.
