This is a newly updated duplex with both units being sold for one price. The property has new paint throughout, both interior and exterior (painted June, 2026), all new kitchen appliances (June, 2026), and new flooring and new carpet throughout (June, 2026). Each unit features a laundry room, and 1.5 baths, with the 1/2 bath located on the bottom floor and the full bath located on the top floor. This is a tri-level with no basement. Each unit has its own one-car garage. The property is located in a quiet cul-de-sac and is therefore away from traffic. If you're in the market for a clean rental or a great place to start out, living in one side and renting out the other, this would be a great property for you. We just had it appraised (June, 2026) and are marketing the property $50,000 below appraised value ($645,000).
