An exceptional opportunity to own a modern estate package featuring a completed primary residence, a partially constructed second home, and an income-producing solar field--spanning more than 23 acres in a desirable area of Sanford and North Berwick. Built in 2024 and offered for the first time, the primary home is an custom modern ranch set on 2.4 private acres. Designed for true one-floor living, it features vaulted ceilings, an open-concept layout, striking black cabinetry, quartz countertops, and a spacious island, ideal for entertaining. The living and dining areas flow seamlessly to the rear deck for easy indoor-outdoor living. The finished walk-out basement expands the living space with high-gloss epoxy floors creating an ideal recreation or entertainment area with a custom built in bar. A finished room currently used as a third bedroom provides flexible space for guests or office use. The home is powered by electricity and includes a whole-house generator with a buried propane tank. An oversized three-car garage with extra tall doors offers ample storage and vehicle space. Above the garage is a fully finished 1-bedroom ADU with private entrance, kitchen, bathroom, and its own laundry--ideal for extended family or rental potential. Also included is a 21.2-acre parcel with a partially constructed ICF home. Permits are secured, septic design completed, well lines installed, and plans for a 2-bedroom, 2.5-bath home are included. Approximately 7.5 acres are under a 25-year solar lease generating over $20,000 annually (lease available upon contract). The solar has it's own private access on the opposite side of the property, and will be completely out of view from the 2 existing homes. Zoning requires 2-acre lots, offering potential subdivision (buyer to verify). A rare opportunity combining lifestyle, income, and development potential in one offering.
