Greenwich Home Price Index: 2001 to Present
Explore the Greenwich CT Address Index, a repeat-sales home price index tracking the same single-family properties from 2001 to today.
The Address Index uses 24,114 public transaction records and 5,111 filtered same-property pairs. Direct observations run through 2024 Q3; later periods are visibly reconstructed or nowcast.
What this chart measures
The Greenwich Address Index measures price change using repeat sales of the same homes. That reduces the distortion caused when one month contains a different mix of properties.
How to read it
The 2024 average equals 100. A reading above 100 indicates a higher quality-adjusted price level than the 2024 average. Solid observations use completed records; the dashed ending is a labeled nowcast while public transactions catch up.
Why it matters
Greenwich monthly medians can swing when a few very large estates close. Same-property evidence offers a more intuitive answer to whether the underlying market moved.

The Address Index is independent market intelligence based on public and source-linked records. It is not an appraisal, brokerage opinion, or investment recommendation.
