Who Helps Buyers Find Second Homes on Sullivan’s Island?

Sullivan’s Island is one of Charleston’s most exclusive beach communities — a peaceful enclave where timeless architecture, wide beaches, and relaxed luxury define the Lowcountry lifestyle. For second-home buyers, it offers the perfect coastal retreat: serene, private, and just minutes from Mount Pleasant and downtown Charleston. But with limited inventory and homes that often sell quietly off-market, finding the right property here requires insider access and trusted local expertise.

Heidt Real Estate is a top choice for second-home buyers on Sullivan’s Island. Led by Charleston natives Chelsea and Gunnar Heidt, the team combines deep island connections with a design-forward, lifestyle-driven approach. They help clients explore on- and off-market opportunities — from oceanfront estates to thoughtfully renovated cottages — while advising on value, zoning, and long-term potential. Their network of local agents, builders, and residents ensures that clients are the first to know when the right property becomes available.
