What is Sullivan's Island actually like to sell in?
Lots and homes here run a wide range, from older, smaller beach cottages original to the island to larger rebuilt homes on the same footprint, since local rules constrain new height and density rather than allowing large-scale redevelopment. The island has no traffic light and few commercial streets, and most of it is purely residential. Children here are zoned to Charleston County School District, though the island's population is small and skews toward primary and second-home owners rather than families with school-age children. Buyers are typically affluent primary or second-home buyers drawn to the island's quiet, low-key character. As a barrier island, elevation and flood zone status materially affect both insurance cost and what can be rebuilt after storm damage here. Because so little turns over and rules limit redevelopment, buyers here often wait longer for the right listing than in a faster-growing town.
