Not every address inside Grand Harbor's gates carries a seven-figure price tag, and St. Joseph's Island is the clearest argument for that point. This established enclave of attached villas sits among the community's roster of named islands, offering a way into full Grand Harbor ownership that a growing number of buyers now find more practical than a stand-alone estate. The floor plan here has stayed remarkably consistent since the enclave was built: roughly 2,300 square feet, three bedrooms, three baths, and an attached garage. Interiors tend to arrive well finished, and sales have included fully furnished, turnkey transactions, a detail that speaks to how many owners here use the home seasonally rather than year-round. The appreciation curve tells its own story. A St. Joseph's Island villa that traded for roughly $460,000 to $500,000 in 2018 is listed today in the mid-$600,000s to high-$600,000s. Listings here move through a wide bench of brokerages, a sign of a genuinely liquid, actively traded market rather than a quiet backwater. Ownership carries the same standing as any address in Grand Harbor: the Pete Dye–designed Harbor Course and the Joe Lee–designed River Course, a 32,000-square-foot Mediterranean-style clubhouse, a protected deep-water marina, tennis and fitness facilities, and a private oceanfront Beach Club a short drive away. Club membership is optional and available in multiple categories. For a buyer who wants the address, the amenities, and the lifestyle without the maintenance calendar of a riverfront estate, St. Joseph's Island is where the math works.
