The six-bedroom house at 14 Red Knot Road was completed in 2025 and spreads its rooms over three floors, from a main-level primary suite to a top-floor flex room and a guest suite above the garage. It sold for $3.10 million, the highest of five reported sales across the Hilton Head Island metro area for the week ending September 20, 2026, which together came to $11.02 million.
Water runs through the rest of the list: a Sea Pines house looking across a tidal salt marsh toward Calibogue Sound, a Hampton Lake home with a private dock, a renovated Windmill Harbour residence above a lagoon and a Callawassie Island house facing Chechessee Creek. The five closings all sit inside named Lowcountry communities in Bluffton, on Hilton Head Island and in Okatie, and the houses date from 1983 to 2025.
No. 1 — $3,100,000 · 14 Red Knot Road, Bluffton, South Carolina
A six-bedroom house completed in 2025 in Palmetto Bluff sold for $3.10 million on September 15, 2026, giving Bluffton the metro area’s highest reported closing of the week. The residence covers a reported 5,152 square feet arranged over three floors.
Lowcountry architecture and an open floor plan put the great room in direct line with a kitchen fitted with a commercial-grade refrigerator, a gas range, an expansive island and premium finishes. The primary suite sits on the main level and includes a soaking tub, a walk-in shower and a generous walk-in closet. Three ensuite guest bedrooms occupy the second floor alongside a dedicated office, and the third level holds a flex room.
A screened porch with an outdoor dining area and a fireplace opens off the great room for year-round use, and the second-floor covered porch looks out over park space and a pond. A separate guest suite above the two-car garage adds accommodation apart from the main house.
Palmetto Fine Homes and David Jarman of Corcoran HM Properties – Bluffton were the listing agents. The $3.10 million closing put them at the listing side of RealtyWire’s highest-priced reported sale in the Hilton Head Island metro area for the week ending September 20, 2026. David Johnson of Palmetto Bluff Real Estate Co represented the buyer.

An elevator serves the floors and there are multiple fireplaces. The lower level holds a recreation room, a full bath and a second laundry room, all reachable straight from the pool.
Both rear porches and a lower poolside terrace overlook the swimming pool and the tidal salt marsh that stretches out to Calibogue Sound and the Intracoastal Waterway, and the grounds have been kept as natural landscape rather than formal lawn.

No. 4 — $1,580,000 · 55 Crosstree Drive, Hilton Head Island, South Carolina
A 1997 house on a corner lot above a lagoon in Windmill Harbour placed fourth. It changed hands on September 18, 2026 for $1,580,000 after a renovation that reworked the interior.
A front porch and French doors open onto white oak floors that run through a reported 3,442 square feet. The kitchen combines custom illuminated cabinetry, GE CafΓ© appliances, an oversized porcelain farmhouse sink and brass-accented shelving around a large island, with a back pantry behind it for glass-shelved storage and a beverage refrigerator. An oyster shell chandelier and grasscloth wallpaper set off the dining room, while the living room carries custom built-ins, detailed millwork, a gas fireplace with a quartz surround and walls of windows.
A split floor plan upstairs puts the primary suite over the lagoon beneath exposed wood beam ceilings, with dual custom walk-in closets and a bath holding a freestanding soaking tub, an oversized shower and a double vanity. A second guest suite there has custom closets, an updated bath and its own flex room, and the laundry is on the same floor. Downstairs, a guest suite now used as an office adjoins a marble bath.
Outside, a tabby shell paver patio faces the lagoon and a brick courtyard strung with cafΓ© lights sits alongside it, with a covered breezeway connecting the house to a detached two-car garage. Windmill Harbour is home to the South Carolina Yacht Club and a private marina, and the community is golf-cart friendly. The property previously changed hands for $754,900 in 2021.

No. 5 — $1,467,500 · 12 Dolphin Lane, Okatie, South Carolina
Listing materials identify Steve Tilton of Coastal Signature Home as the builder of the 2015 house at 12 Dolphin Lane, which sits on a private cul-de-sac on Callawassie Island with northeastern exposure. The sale was completed on September 14, 2026 at $1,467,500.
Panoramic views over Chechessee Creek and the surrounding marshlands reach the living room, kitchen, breakfast nook, family room, primary bedroom and a guest bedroom, with indirect sunrise and sunset light. Three of the four bedrooms are on the main floor, which allows for one-level living.
Random-width reclaimed pine flooring and rich millwork run through a reported 3,554 square feet that holds formal living and dining rooms alongside an open family room and kitchen under a 16-foot vaulted ceiling. The kitchen is appointed with premium appliances and a gas cooktop, and the refrigerator was replaced in 2025.
A 400-square-foot screened porch with a gas fireplace faces the water, and a 536-square-foot bonus room with a full bath and a ceramic tile shower was added in October 2024. A tankless water heater, a walk-up attic insulated with spray foam and an insulated crawl space serve the house, and the exterior was repainted in May 2026. The property previously changed hands for $70,000 in 2013, before the current residence was completed in 2015.
For listing agents Grace Vandiver and Lowcountry Specialists of Charter One Realty, the property went under contract the same day the current listing went live, and the $1,467,500 closing rounded out RealtyWire’s Hilton Head Island metro area Top 5 for the week.
