- Description: 630 Rattlesnake Island offers a rare chance to own a boat-access-only property with approximately 300 feet of waterfront on the Broads of Lake Winnipesaukee, one of the lake's most sought-after settings for big water views, privacy, and the kind of peace that has become almost absurdly hard to find. Set on about 1.5 acres and built on a ledge for a dramatic natural perch above the lake, this is the sort of setting buyers wait for and seldom see at this price point. Built in 1999, the home has solid bones and the unmistakable feel of a cherished family camp. It has not been used for several years and will require updating and TLC, but the opportunity here is not hard to see. For the right buyer, this is a chance to restore, refresh, and reimagine a true Winnipesaukee island retreat in a location where value is driven by frontage, privacy, and setting first. The existing home offers the foundation for something special, whether the vision is a comfortable seasonal escape, a legacy property to keep in the family, or a thoughtful renovation that brings new life to an already remarkable site. There are simply not many opportunities left to purchase this kind of waterfront footprint on Rattlesnake Island with this level of seclusion and potential. Ownership also includes membership in the Rattlesnake Island Association, which maintains mainland access for owners, adding practical convenience to island living. The association owns upper parking and trailer storage plus a lower waterfront area known as The Landing, with launch ramp and transient docks for member use. If you have been waiting for a property where location is the headline, privacy is the luxury, and the upside is real, this is worth your attention.
