Quality, comfort, and new price! There's a reason people say "homes aren't built like this anymore" and you'll recognize it the moment you enter this turn of the century beauty. From the spacious entry hall, to the dual staircases, high ceilings, tall windows, period detail, and comfortably sized rooms, this is a home built to explore. Gorgeous living room with intricate fireplace. Open kitchen/dining room with sliders to the expansive deck. Adjacent family room/den plus laundry room/pantry. Office nook and half bath complete the first floor of the main home. Upstairs brings unexpected treasures - 4 large bedrooms, many interconnected through closets and other niches, destined for a game of hide and seek. Fireplace in primary. Walk up attic for storage or more living space. Updated full bath with shower and claw foot tub. The biggest bonus - a generous apartment connected to the main home - full kitchen with eating area, living room, bedroom and full bath. Fabulous flex space - potential rental income, in-law, home office or teen space. Or, you can incorporate the space back to expand the main home. So many possibilities and potential. Full basement. Beautifully landscaped yard. Located on the corner of a quiet side street. Great walkability - minutes from the Endicott Estate and library, commuter rail, elementary school, middle and high schools, and multiple parks and playgrounds. This is a wonderful home for the savvy buyer. Open House Sunday 11-1
ADU Potential
Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 3,020 sq ft principal dwelling). Lot size: 10,111 sq ft.
Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
