About this home

Set in one of the most sought after towns in the region, this Sunapee property brings together location, privacy, and everyday ease. Just minutes from Mount Sunapee, where winter weekends turn into lasting family memories and close to Sunapee Harbor and local beaches, you’re right in the middle of everything that makes this area special. Set on over 5 acres, a longer driveway leads you in, adding privacy, character, and a true sense of arrival that’s hard to replicate. Built in 2022, the home was designed for convenient one-level living while still offering exceptional flexibility throughout. Inside, the layout flows naturally, featuring an open kitchen and living area, wood floors throughout, and a primary bedroom with its own private bath. The finished lower level offers exceptional flexibility with pre-installed plumbing and electrical already in place for a future kitchen and washer/dryer setup. This thoughtfully prepared space is ready to be finished as a separate in-law suite, providing strong potential for added functionality and value. The curb appeal, attached garage, and clean, efficient design make this a home that feels easy from the start. Whether it’s mornings on the mountain, afternoons by the water, or quiet evenings at home, this property offers a lifestyle that’s hard to match in a location that continues to hold value.
