Tucked into the quiet countryside of Montville, 1058 South Mountain Highway offers the space, flexibility, and relaxed pace that make rural Maine living so appealing. Set on approximately 2 acres, this inviting ranch combines comfortable single-level living with a finished daylight walk-out lower level designed to adapt as needs change. Warm wood details create a welcoming feel on the main level, while the lower level adds exceptional versatility. In 2018, the space was converted to an in-law apartment with a kitchenette, full bathroom, and separate exterior access. The full-bath addition increased the finished below-grade area by approximately 42 square feet. A separate driveway provides convenient lower-level access, making the space well suited for extended household living, guests, a home office, or other flexible uses. Comfort and efficiency are supported by three heat pumps--two upstairs and one downstairs--plus a furnace and tankless water heater installed in 2024. The roof was replaced in 2018. Additional improvements include a paved driveway, water softener, rebuilt 9'x16' back deck, propane connection for grilling, and generator hookup. Outside, enjoy room to garden, fenced space for pets, a detached one-car garage, and a peaceful setting with the rear of the property at the base of Hogback Mountain, abutting land not anticipated to be developed. Belfast's waterfront, restaurants, shops, and Penobscot Bay are within easy reach, along with Unity and the lakes, trails, and recreation of the surrounding area. A versatile Maine home with room for life to evolve.
