The lower unit includes an in-unit laundry room, while the upper unit has its own dedicated laundry room located downstairs. Both units offer the convenience of a private one-car garage, a highly desirable tenant amenity. The property also includes a shared front common area and a large backyard, great for parties and activities. This duplex is well-suited for investors seeking a stable income property with value-add potential.
