About this home

Views and a sensational deck make this property all about the outdoors! With 2 bedrooms and a loft, lots of sleeping space for your family. Island charm abounds, you even have a working, decorated outhouse! But no worries there is an indoor incinolet toilet. Your heating and cooling needs are taken care of with Mitsubishi heat pump. All you have to do here is move in as there is a newer roof and siding. A crib dock and a seasonal 4' x 20' dock to fit your boats. Come see this adorable cabin before it is gone! There is a mainland dock available at Minge Cove for additional monies. Rattlesnake is an association island with fantastic mainland amenities, including parking, a pick up/drop off dock, and hiking trails on the island with some of the best views on the Lake.
