A profitable duplex, or a four-bedroom, two-bath single-family use home? This exceptional property offers the best of both worlds, situated on a large, level lot in San Geronimo. Previously occupied by one family, the dividing wall between the two units has been removed, creating a seamless living environment. The wall can easily be reinstalled to restore the property to two separate units, each with its own expansive, level yard. Each 2-bedroom, 1-bath unit features wood flooring, an updated kitchen and bathroom, air conditioning, and a private garage. The unit that is at the far end of the lot can easily be expanded and use both attached garage spaces for an owner user or VRBO country rental. Alternatively, enjoy the home as a generous single-family residence with an oversized yard ideal for outdoor living, entertaining, or future possibilities. Located in the heart of West Marin, this home is surrounded by open space preserves and offers reasonably easy access to north county beaches, hiking trails, road and mountain biking, and horseback riding -even room for your horse! A rare opportunity to enjoy flexibility, space, and an unparalleled natural setting just outside your door. Vacant units rents are estimated at $3,000 per month per unit.
