About this home

Rare Greenwich opportunity! This side-by-side duplex at 9 Columbus Ave sits on a quiet dead-end street in Chickahominy - offering the perfect house-hack setup: live in one unit and rent the other, or hold both as a turnkey investment. Each unit features 2 bedrooms and 1.5 baths across 1,112 sq ft of well-designed living space, for a total of 2,280 sq ft. Built in 1997, this move-in ready property offers newer construction quality that's hard to find at this price point in Greenwich. Whether you're an owner-occupant looking to offset your mortgage or an investor seeking cash flow in one of Fairfield County's most desirable towns, 9 Columbus Ave delivers flexibility, privacy, and long-term value on a peaceful street just minutes from Greenwich Avenue, the train station, and all that downtown Greenwich has to offer. Two homes, endless possibilities - don't miss this one.
