Property Description
An exceptional opportunity to own a rare commercial marina on Lake Sunapee, ideally located in the village of Georges Mills. This waterfront property spans 0.86 acres with approximately 205 feet of shoreline, offering prime lake access and business visibility.

The property includes four distinct structures, offering a flexible combination of commercial and residential potential. There is a Colonial-style main residence suitable for year-round living, staff housing, or rental. A standalone cottage provides seasonal accommodations or additional rental income. The retail building includes a 2nd-floor living space and attached single-bay boat house, ideal for marine services, equipment rental, or retail operations. Additionally, the property has an extra bonus outbuilding. Located adjacent to the Georges Mills public boat ramp and town beach, this property enjoys high seasonal traffic, excellent visibility, and convenient access for both residents and visitors. Whether you're looking to run a marine-based business, create a lakefront investment property, or develop a unique live/work compound, this property offers unmatched potential on Lake Sunapee.
