Greenwich, CT

Greenwich occupies the southwestern corner of Connecticut, bordering New York State and Long Island Sound — a location that has made it one of the wealthiest communities in America for over a century. The town's property landscape reflects that position: expansive estates along the waterfront and in the backcountry, a walkable downtown along Greenwich Avenue, and neighborhoods that range from modest mid-century homes to properties assessed in the tens of millions.

The town's 48 square miles encompass a remarkable range of environments. The Long Island Sound coastline brings coastal flood exposure and storm surge risk. The inland backcountry, with its wooded hills and private roads, presents different challenges — longer fire department response times, private wells and septic systems, and properties where lot sizes are measured in acres rather than fractions. Between these extremes, the village centers of Old Greenwich, Riverside, and Cos Cob each have their own housing stock character.

Greenwich's property market moves at a scale and pace that demands current intelligence. With some of the highest property values in the northeast and an active transaction market, professionals working here need precise, property-level data on condition, environmental exposure, and building characteristics — not regional averages that blur the enormous variation within the town's borders.
