About this home

HIGHLY SOUGHT AFTER location on Rattlesnake Island, Lake Winnipesaukee. The completely updated two bedroom home sits mere steps from the lake. Situated on the western side of the island and south of the peninsula, the property is protected from the prevailing winds, boasts all-day sun, 180 degree stunning views, and crystal clear water. From the moment you idle your boat into your covered slip, you will notice the attention to detail both inside and out. Lakeside offers multiple docks for guests, several different seating areas, and a meticulously landscaped shoreline. The expansive deck offers a perfect extension to your living area with custom wire railings and plenty of room for entertaining. Inside, the house is tastefully updated, with two large bedrooms both offering sliders out to the deck with beautiful lake views. Mini splits will keep you comfortable no matter what the temperature is outside. Truly island living with all the comforts of home. A backup generator is wired in the tool house, just in case. Rattlesnake Island also offers hiking trails right from the back of this property. From sunrise to sunset, the scenery of this Island Retreat will take your breath away!! This property does not miss a beat when it comes to Lakefront Living!! BACK UP OFFERS BEING ACCEPTED. We will continue to show.
