About the property

Turnkey Harbor Island 3BR/2BA — Marsh Views, Private Deck & Golf Cart

Step into a fully furnished Harbor Island home that performs as beautifully as it feels. This single-story, 3-bedroom / 2-bath retreat offers 1,517 square feet of carefully updated living space, a remodeled kitchen with brand-new appliances, and guest-ready furnishings that produced an impressive $61,000 in the first year of vacation rental operation. The layout is straightforward and livable — living and dining flow from the kitchen, and the private deck presents direct marsh sightlines that change by the hour.

Owners will appreciate the ease of island living: an included golf cart makes beach runs and community errands simple, and the property sits steps from Harbor Island’s resort-style amenities — multiple pools, tennis and pickleball courts, and private beach access reserved for residents. Interior finishes such as durable laminate floors and a turnkey furniture package reduce upkeep and accelerate rental readiness.

Outside, the compact lot is low-maintenance and the elevated deck is the ideal spot for evening cocktails while watching egrets and tides. Practical features include a 1-car carport and easy entry/egress from Nautical Watch Way. The listing is being offered fully furnished to enable an investor to step into management without a lengthy fit-out.

Whether you’re acquiring a high-performing short-term rental or a quiet island base with instant income, this Harbor Island property blends proven cash flow with lifestyle upside. Showings by appointment; please confirm availability and rental-booking schedules with the listing agent.

Editorial market perspective

Harbor Island is a niche, private-beach submarket within Beaufort County that typically trades at a premium to the broader county due to limited inventory and resort amenities. Buyers currently face a moderately tight market for turnkey vacation-ready homes — inventory remains seasonal but constrained, keeping demand robust, particularly for furnished, income-producing units. Median sale prices in nearby coastal neighborhoods sit well below this listing, but Harbor Island’s private access and amenity package command higher price-per-square-foot metrics (this listing at ~ $448/sf). Short-term rental performance is a material value driver here — reported first-year revenue of $61K significantly enhances yield and marketability. For buyer strategy: bring competitive financing and confirm insurance/flood costs early; for sellers: maintaining the turnkey, furnished offering will attract investor buyers willing to pay a premium.
