Exceptional island living awaits on Rattlesnake Island, where this pristine Lake Winnipesaukee home combines an elevated level of finish with spectacular long-range views and a beautifully maintained waterfront setting. Set on .65 acres with approximately 99 feet of shoreline, this three-bedroom, two-bath home has been meticulously cared for and thoughtfully enhanced with initial renovations completed in 2009, creating a truly special island retreat. At the heart of the home is a gorgeous kitchen and dining area, added in 2014 and beautifully appointed with granite countertops and stainless steel appliances. Designed for both everyday living and entertaining, it flows naturally into the spacious great room, where generous windows capture the surrounding lake views and a propane stove adds warmth and extends the season well beyond summer. A first-floor primary bedroom offers comfort and convenience, while two exceptionally spacious bedrooms above each enjoy beautiful views of Lake Winnipesaukee. Throughout the home, its pristine condition and thoughtful details reflect an unmistakable pride of ownership. Outside, an expansive front porch becomes an extension of the living space, with plenty of room for dining, entertaining, and relaxing against a sweeping Winnipesaukee backdrop. It is an idyllic setting for long summer afternoons, evenings with friends, and taking in the beauty of the lake. Owners enjoy convenient access to the Rattlesnake Island Association's mainland facility, 'The Landing,' with parking, trailer storage, boat launch, and docks for loading and unloading. Scenic walking trails wind throughout the island, offering another way to enjoy its natural surroundings. Beautifully appointed, impeccably maintained, and ready to enjoy, this is island living at its finest.
