1600 Koch Road Looking for multigenerational living or the potential for additional income with a second home as an Airbnb or short-term rental? Incredible opportunity to own 5.23 acres featuring two homes, an oversized detached two-car garage, and a beautiful setting backing to woods and a creek! This charming two-story main home offers 3 bedrooms, 1 full bath upstairs, and much of its original architectural character and beauty. Enjoy an updated kitchen with stainless steel appliances, fresh neutral colors throughout, and plenty of space for entertaining. The basement offers additional finished space for gatherings, recreation, sleeping space, and storage. Recent improvements include an updated electrical panel, roof, and basement windows. The septic system has been serviced every two years. The second home has been beautifully updated from a previous structure and offers a charming studio-style layout featuring 1 bedroom, 1 full bath, kitchen, living and dining areas, and a convenient laundry closet. Perfect for extended family, guests, or potential rental opportunities! Additional highlights include an oversized driveway, ample parking, and an oversized detached two-car garage conveniently located next to the main house. And the "potential" to add an additional structure further down from the secondary home and "possibly" with it's own entrace! A Choice Ultimate home warranty with added well and septic coverage is also included! With 5.23 acres, two residences, and a peaceful wooded backdrop, this unique property offers endless possibilities and is truly a must-see!
