About this home

Full of potential, this 2-bedroom, 1-bath ranch offers 1,200 sq ft of natural light from large windows, a spacious living room, eat-in kitchen, and a separate dining room that could convert to a third bedroom. A true blank slate, ready to become your private woodsy retreat! Additional features include a covered front porch, unfinished walkout basement, and tuck-under garage. Recent updates include a new roof and gutters (2024) and a new septic system (9/2025) designed to accommodate a 3-bedroom layout, offering flexibility for future expansion. Car enthusiasts and hobbyists will love the 728 sq ft detached garage (1996) with a separate electrical panel and 220 power, providing a huge workshop space. Situated on a secluded wooded lot backing to common ground, yet minutes from shopping, dining, and major highways in the award-winning Parkway School District!
