The island parcel spans approximately 2.1 acres with expansive sandy frontage and features a beautiful 5,000+ sq ft residence with panoramic water views and multiple balconies. Inside, you will find a chef's kitchen, formal dining room, several private guest suites, a top-floor primary suite with a walk-in closet and large bath, and a walk-out lower level with a game and entertainment area, full bar, Jacuzzi room, and additional bedrooms and baths. Recent thoughtful upgrades and modern systems make this a turnkey lake-living opportunity. The grounds are meticulously landscaped with multiple sitting areas, a waterfall feature, integrated lighting, an underground sprinkler system, and a whole-property speaker system. Utilities include city water and sewer, electric, gas, and a backup generator. The compound supports many uses, including full-time living on one parcel and rental income from the other, private events, or a multi-generation retreat. The mainland home is approximately 1,000 sq ft and offers an open-concept living, dining, and kitchen area, two bedrooms, and one and a half baths with direct sightlines to the island. The property includes two-car garages at street and lake levels, a private boat launch, a large dock, and dedicated storage for water toys and lifts.
