Significantly. Greenwich is not a single, uniform market. Old Greenwich and Riverside are coastal, walkable, and family-oriented, they attract a specific buyer pool and command premiums accordingly. Backcountry and North Greenwich are estate territory, with large acreage, equestrian properties, and the highest price points in town. Cos Cob offers more accessible entry points with strong community character. Byram, Glenville, and Pemberwick sit closer to the Stamford border and represent the lower end of the Greenwich pricing spectrum. Each area has its own dynamics around school districts, septic versus sewer, flood zone considerations, and proximity to Metro-North stations like Cos Cob, Riverside, and Old Greenwich. A CMA that doesn’t account for these distinctions is not a useful CMA.
