About This Home
Rare, fully leased legal three-family in the heart of Cos Cob--a turnkey investment in one of Greenwich's most desirable neighborhoods. All three units are occupied and income-producing, with separately metered gas and water that keep owner costs low and net income clean. Updated mechanicals mean reduced capital risk and genuine turnkey ownership. Hardwood floors, high ceilings, and abundant natural light give each unit lasting tenant appeal, plus off-street parking. Minutes to Metro-North, top Greenwich schools, shops, and dining. Legal three-families are a true rarity here--dependable cash flow today with built-in rental upside tomorrow. Full financials available upon request. An exceptional opportunity for investors and owner-occupants alike.
