Thinking about relocating to Greenwich?

A few practical considerations as you evaluate the move:

• Pick the ZIP, not just the city. Median income, school assignments, walkability and crime patterns can vary dramatically between neighboring ZIPs in the same city. Use the per-ZIP pages to compare.
• Compare housing math honestly. The median home value here is $1,621,650, and median rent is $2,339. At current mortgage rates, that often makes renting the more flexible option for the first 12–24 months while you learn the neighborhoods.
• Verify the commute. Drive your prospective work or school route at peak time — Google Maps optimistic estimates rarely match what locals actually experience.
• Check the boring stuff. Property tax rates, HOA dues, flood-zone designation, and homeowner's insurance availability are easier to research before you sign than after.
