Offering 5 bedrooms, 3.5 baths, and over 4,000 sq ft of living space, the home features classic plantation-era craftsmanship, soaring ceilings, wood details, and gracious rooms oriented toward serene garden views. Listed on the State Historic Register, the property can potentially benefit from exceptionally low real property taxes (approximately $200/year)—a rare advantage for an estate of this scale and history, Buyer to do their own due diligence. The compound spans two TMKs, so there is an option to build another residence and also includes multiple historic structures: the original caretaker’s cottage, a garage/workshop, and a separate storage building. Zoned RS-15, the property offers space, privacy, and a timeless sense of place.
