These were the five highest-priced home sales reported in the Charleston metro area for the week ending October 18, 2026, and together they came to $21.85 million. All five are two-story single-family homes, spread across Mount Pleasant, Isle of Palms, Johns Island and two Charleston neighborhoods, and four of them are in Charleston County, with the fifth across the line in Berkeley County. Only one of them is new construction.

On Isle of Palms, 28 22nd Avenue sold for $4,000,000. The beach is a few blocks from the home, and so are the island’s Recreation Center, its parks, and local shops and restaurants.

A separate wet bar has its own sink and wine and beverage refrigeration.
The screened porch has a gas fireplace, and open decks look down on the pool and backyard.

A covered entertainment area adds the home’s third gas fireplace, a granite-topped bar with refrigeration and an outdoor television.
Materials were chosen with the coast in mind. The roof is aluminum standing seam and the siding is cement board, the windows and doors are impact rated, and the decking is IPE, finished with stainless steel cable railings.
