What is the average Sullivan's Island house price in May 2026?

An average price for Sullivan's Island in any given month would blend a small number of very different sales, from a modest inland cottage to a large oceanfront estate, in a way that tells a buyer almost nothing useful about their own situation. A current comparative market analysis on a specific address or comparable street gives a far more accurate number than any monthly average. Brian Beatty prices the street, not the island average, especially in a market this thin.
