About This Home

15 Cooper Street

An exceptional opportunity to own a rare residential mixed-use waterfront property on Lake Sunapee, ideally located in the village of Georges Mills. This unique offering spans 0.86 acres with approximately 205 feet of shoreline, combining private residential living with income-producing marina and commercial capabilities. The current configuration accommodates parking for 14 boats and includes a gas dock—one of only three fuel stations on Lake Sunapee—providing both convenience for residents and a valuable service for the boating community. The property includes four distinct structures that support flexible residential and mixed-use living. A Colonial-style main residence offers comfortable year-round living, while a standalone cottage provides guest accommodations or rental income. The retail/marina building features a second-floor living space and attached single-bay boat house, allowing for a live/work setup ideal for marine services, equipment rental, or small retail use. An additional outbuilding offers further storage, workshop, or accessory-use potential. Located adjacent to the Georges Mills public boat ramp and town beach, the property benefits from strong seasonal activity while maintaining the appeal of a private waterfront residence. This versatile mixed-use property is well suited for an owner-occupant seeking a lakefront home with business potential, multi-unit residential income, or a unique live/work compound on Lake Sunapee. Buyer to complete due diligence relative to property bounds, room and building sq, footage and potential town approvals for multi unit rentals. Sqft. listed is the total available of all buildings.
