Property Description

House of Many Doors. Opportunity takes many forms, and this home gives you the flexibility to make it your own. With 7 bedrooms, 2 kitchens, 2 primary suites, 2 laundry areas, and a floor plan designed for a variety of living arrangements, this is an ideal fit for multigenerational living, extended family, rental income, or provides room to spread out. Step inside to warm wood floors, a bright living room lined with built-in bookshelves, a wood-burning stove, and a stunning wood-paneled ceiling that creates an inviting place to gather. Sunny breakfast nook & kitchen overlook the expansive backyard, bringing peaceful views. The main-level primary suite is a true retreat with soaring ceilings, sitting area, walk-in closet, private laundry, patio access, and five-piece bath with a soaking tub. A dedicated home office and an additional bedroom provide flexibility. A separate wing of the home has been successfully used as an Airbnb and is tucked away with its own private entrance, living area, two bedrooms, and exceptional privacy. Whether you're accommodating long-term guests, generating supplemental income, or creating an independent living space for family, the possibilities are endless. An additional kitchen, second living room, and second laundry area enhance the home's versatility. The second living room is ready with chimney for wood stove. Upstairs, the second primary suite features vaulted ceilings, a walk-in closet, and an ensuite bath. Outside, nearly half an acre becomes your own private sanctuary. Enjoy the covered deck overlooking a backyard filled with mature trees, established vegetable gardens, a farmer's ditch, and frequent visits from deer, ducks, and birds. Multiple fenced areas and a dedicated dog run make the outdoor space as functional as it is beautiful. Tucked into a welcoming neighborhood, this home offers something increasingly difficult to find: flexibility, privacy, income potential, and a backyard that feels like your own peaceful park.
