First-floor primary suite offers true one-level living once inside this renovated 4-bedroom Hollis home, set on a private 1.4-acre lot lined with mature trees. Three additional bedrooms upstairs provide flexible space for family, guests, or a home office. Major improvements are already complete, including a brand-new, state-approved 4-bedroom septic system and new heat pump with central AC. The updated kitchen features new appliances and generous workspace and opens to connected living and dining areas. Fresh paint, updated flooring, newer windows and siding add to the move-in-ready condition. The first floor also includes laundry and a half bath, with a second full bath upstairs. Outside, the property offers a covered front porch, space to garden, and a separate storage barn with workshop or hobby potential. A one-car under-house garage provides additional storage and parking. Entry to the home requires a few steps at both the front and side doors. Convenient to Hollis-Brookline schools, Hollis town center, local farms and trails. Updated, functional, and ready for its next owner.
