Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Apr 2026 - Jun 2026).

Harbor Island’s rolling three-month snapshot through June 2026 shows a market picking up speed. Homes sold jumped sharply month over month, and new and pending listings also rose, while typical home values climbed and months of supply dropped.

Compared with a year ago, sales activity has grown significantly. Homes sold and pending sales are both up strongly year over year. Inventory has also increased, with more active listings and new listings coming to market.

Pricing trends show typical home values up notably from last year, while the median list price has changed only slightly, suggesting buyers are seeing more options across price points. Homes are spending a median of 158 days on the market in this rolling period, yet the share selling above list is small and the average sale-to-list ratio sits just under 94 percent, pointing to more room for negotiation. Months of supply, now around 5 months, has fallen sharply from earlier, shifting conditions closer to balance even though it is still labeled a seller’s market. In this evolving environment, both buyers and sellers can benefit from Agent Pronto’s help in finding a local agent who understands Harbor Island’s current trends.



Learn more about what Harbor Island has to offer.

Harbor Island offers residents a serene waterfront lifestyle, secure, well-maintained amenities, and a welcoming, active community.

Harbor Island offers a relaxed, coastal pace where days often revolve around the tides, the weather, and time outdoors. Residents wake to quiet streets, salt air, and easy access to the wide Atlantic beach, with everyday errands and services available in nearby Beaufort and Port Royal. Many homeowners split time between primary residences elsewhere and second homes here, so the island stays peaceful even in peak season.

Life centers on the waterfront. The beach and tidal marshes are ideal for walking, shelling, and casting a line, while nearby Hunting Island State Park adds hiking trails, a historic lighthouse, and campgrounds. Golfers often head toward courses in Fripp Island or Lady’s Island, and boaters appreciate access to the Beaufort County waterways and fishing grounds. For dining and culture, residents frequent spots in downtown Beaufort and enjoy events from organizations like USCB Center for the Arts.

Because Harbor Island is a gated barrier island with a mix of single family homes, villas, and vacation properties, choosing an agent who understands short term rental rules, HOA regulations, and local flood and insurance considerations is essential. A knowledgeable local professional can help you weigh rental income potential against personal use, time your sale to seasonal demand, and navigate inspections in a coastal environment. Agent Pronto connects both buyers and sellers with the right Harbor Island agent so you can move forward with confidence.

“Mrs. Alyssa Graves has proved herself to be the most proficient, persistent, patient, prompt and professional individual I have encountered in many decades of negotiating more than 50 real estate purchases. There is a phrase from the French ... "Non plus ultra" which applies here. Personally, I wish I could think of a way to express my gratitude for Alyssa standing by this difficult old couple - finding and showing us practically every house in our market segment ... through 7 detailed evaluations & offers, 4 signed contracts for sale, 3 home inspections - and ultimately to find and buy what may be our last home. But here is the best I can do: Thank you m'am.”
