About This Home

As of December 2025

OPEN HOUSE CANCELLED! Seller has accepted an offer! Absolutely Fantastic property on Knop’s Pond/Lost Lake in Groton MA. The year round home has Five acres & approximately 260 plus feet of frontage on the lake. The home itself sits atop a knoll with breathtaking views. The side yard has a gentle slope to level area perfect for family gatherings, fire pit, garden area, etc. For the last 60 plus years, the current owners enjoyed their dock, boating, kayaking, fishing, swimming etc. There is a newer forced hot air heating system (within last 3 years) & a newer oil tank & well pump (within last 8-9 years). The home is in need of work & is priced accordingly. The property will not qualify for conventional financing due to the failed Septic. It is unknown if the 5 acre parcel can be subdivided. Buyer & buyer’s agent must do own due diligence. The property is being sold as is and the seller is requesting a quick closing.
