This home has an unmistakable charm that immediately feels welcoming. A wall of glass frames expansive water views while filling the open living space with natural light. The living room features a propane fireplace, complimented by electric baseboard heat to comfortably extend the season. Outdoor living is equally well considered, with a wraparound porch featuring a retractable awning for shaded dining and relaxation, along with a separate lakeside deck positioned just steps from the water. A 6' x 30' permanent dock provides convenient lake access. A beautiful sandy lake bottom at the water's edge provides ideal conditions for swimming. The property has been carefully maintained with significant recent improvements, including a two-bedroom state-approved septic system installed in 2019 and a metal roof replaced approximately seven years ago. Two detached outbuildings provide exceptional flexibility. One serves as dedicated storage for tools and equipment, while the second offers additional finished space well suited for guests, hobbies, or a quiet remote office. The property is level and open providing ample room for traditional island activities like horseshoes or corn hole. Situated on the southern end of the island, facing Alton mainland, property has fantastic exposure. The Owners enjoy convenient access to the Rattlesnake Island Association's mainland facility, "The Landing," which includes parking, trailer storage, a boat launch, and docks for loading and unloading. Scenic walking trails throughout the island offer opportunities to explore its natural landscape. This is a well-cared-for island property offering comfortable accommodations, practical improvements, and easy access to the mainland in one of Lake Winnipesaukee's most established island communities.
