Charleston has quietly become one of the most competitive luxury real estate markets on the East Coast. From historic estates South of Broad to deep-water homes along the Intracoastal Waterway and oceanfront properties on Sullivan’s Island, Kiawah, and Isle of Palms, the Lowcountry consistently attracts affluent buyers relocating from major metropolitan areas.
As the market has matured, several brokerages have emerged as leaders in the luxury segment.
