About this home

This beautiful Colonial sits on a quiet cul-de-sac in Holbrook and offers plenty of room for everyday living and entertaining. Set on a beautifully landscaped property with a multi-car driveway and a 2-car garage, this home offers so much! The first floor features a living room, family room, formal dining room, updated kitchen, convenient laundry room, and half bath. Hardwood floors throughout add warmth and charm. Upstairs, you'll find four generously sized bedrooms, a full hallway bath, and a spacious primary suite with walk-in closets and a private bath. The full finished basement with an outside entrance and full bath offers even more space for entertaining, recreation, or guests. Step outside and enjoy your own backyard retreat with a heated in-ground pool, perfect for relaxing or hosting family and friends. Many major updates have already been completed, including pool liner (2018), windows (2019), roof (2020), central air conditioning (2022), pool heat pump (2025), and refrigerator (2026). Conveniently located near shopping, restaurants, parks, and major roadways, yet tucked away in a quiet cul-de-sac setting. A wonderful place to call home!
