What not to over-assume

Avoid ranking this neighborhood as best for everyone. Greenwich neighborhoods change block by block, and walkability, waterfront access, train convenience, and housing patterns vary.

Do not rely on broad claims about school quality, safety, flood risk, commute time, or property value without current source-specific evidence.

Address-level checks

Compare Cos Cob with Riverside, Old Greenwich, downtown Greenwich, Byram, Glenville, and backcountry. Test East Putnam errands, the station, Cos Cob Library, Bush-Holley House/Greenwich Historical Society, Cos Cob Park, and Mianus River access as separate routines rather than one generic village label.
