Just minutes from Mount Desert Island, 89 Horse Farm Road offers a rare combination of space, versatility, and proximity to one of Maine's most sought-after coastal destinations. Built in 2003 and set on more than 15 acres, this well maintained home features four bedrooms and three bathrooms, including a first-floor bedroom currently used as an office. The primary suite offers a walk-in closet and private en-suite bath, while the spacious kitchen features a beautiful soapstone sink. A standout feature is the approximately 900-square-foot great room above the 3-car garage. This expansive space offers tremendous flexibility for entertaining, recreation, guests, or additional living space. The outdoor spaces invite you to settle in and enjoy the property. A large back deck overlooks the fenced backyard and provides an inviting place to relax or entertain, complete with a six-person hot tub. An on-demand generator, reverse osmosis system, air exchanger, and radiant heat in the basement add comfort and convenience all year round. The 32' x 36' horse barn expands the property's utility, offering a second floor for storage and radiant tubing already installed in both barn and garage slabs for future heating options. This property also provides opportunity for the future. Preliminary work was previously done to explore dividing approximately 3.5 acres from the property for a potential additional lot. Ideally located near Bar Harbor, Acadia National Park, and the Bar Harbor Airport, this property offers privacy, acreage and the opportunity to create a year-round home, a peaceful retreat, hobby farm, or potential short-term rental. The property is serviced by a 3-bedroom septic system. Furnishings are negotiable. Come experience the privacy and possibilities of 89 Horse Farm Road for yourself.
