Set on a quiet 0.23-acre lot in Billerica, this Colonial has been meaningfully updated since 2024 - the kind of work most buyers plan for after closing, already done here. The dining area is anchored by a fireplace, and the layout flows easily from living room to kitchen, with an office and a breakfast nook rounding out the main level. Two full bathrooms, including a walk-in closet off the primary bedroom, keep mornings simple.The updates run deep: a high-efficiency natural gas HVAC system installed in 2024, 95% efficient with a 10-year warranty, a leased SunRun solar array, a rebuilt chimney with a custom stainless steel cap, and a 2025 kitchen refresh with a new stainless oven and faucet. The first floor was freshly painted, and the deck has been cleaned, sealed, and stained twice since 2024.Outside, the streets here are quiet and established, in Middlesex County, with Route 3, I-495, and I-93 all close by - Boston is about 25 miles and a 30-35 minute drive. Nuttings Lake, Vietnam Veterans Park, and the Middlesex Canal Trail are nearby for weekend time outdoors, and Market Basket and the Middlesex Turnpike shopping corridor cover everyday errands.Listed as 3 bedrooms - property record shows a 4th bedroom on the first floor that was opened to the living room to create a more spacious layout. It can easily be converted back to a 4-bedroom configuration at a new owner's discretion.First showings at the open house: Saturday 8/30, 11:00 AM-1:30 PM, and Sunday 8/31, 12:00 AM-2:00 PM.4 Jeffrey Rd is ready for its next owner.
