About this home

This is your opportunity to own a home in the sought-after beach community of Bayville. Well maintained and cared for over the years, this charming Colonial-style home offers timeless character and plenty of opportunity to make it your own. Featuring a welcoming wrap-around porch, approximately 0.3 acres of property, and impressive ceiling height, the home offers a wonderful sense of space and character. The home has been thoughtfully updated with a conversion to gas heat less than five years ago, a tankless hot water heater, sprinkler system, and central air conditioning on the first floor. An added benefit of being in Flood Zone X is that flood insurance is not required, offering additional peace of mind for the next owner. Enjoy everything Bayville has to offer, from beautiful beaches and boating to waterfront restaurants, marinas, local shops, and attractions. Experience the relaxed atmosphere and charm of a true North Shore beach community, where coastal living and small-town character come together.
