About This Property

Welcome to 31 Dehan Street! A lovingly maintained three-bedroom, two-bathroom home with the flexibility for a fourth bedroom, inviting spaces designed for everyday comfort and located in one of the best school districts in town. Inside, hardwood floors flow through warm living areas featuring a wood-burning fireplace, formal dining room, granite countertops, Sub-Zero appliances, central air, and a partially finished basement. Step outside and discover the true showstopper: a beautifully level half-acre surrounded by mature, lush landscaping. Thoughtfully designed for relaxing and entertaining, the backyard offers generous lawn space, an awning, a wide sliding door, and utility connections for a motor home, hot tub, sauna, or Jacuzzi. A two-car attached garage and driveways from both Dehan and Leonard Streets provide exceptional convenience. With Andersen windows, updated mechanicals, and numerous thoughtful improvements, this is a home where comfort, beauty, and possibility come together.
