A clearer way to read exceptional local real-estate markets.
The Address Index is independent, source-linked market intelligence for buyers, owners, brokers, and advisers. We are starting with Greenwich, Connecticut—and building a repeatable way to understand the places where a single headline rarely tells the whole story.
Starting with Greenwich
Most market reports begin and end with monthly medians. We add a historical repeat-sales index, current inventory and market-speed signals, property-level Synthetic Twin analysis, and a live interactive dashboard.

What readers receive
A concise weekly read on what changed and why it matters.
The Greenwich Address Index, tracking same-property price evidence from 2001 to today.
Original charts covering inventory, closings, time on market, price momentum, and market heat.
A Synthetic Twin analysis that places one notable sale beside its closest earlier public-record comparisons.
A source-linked watchlist of meaningful planning, zoning, parcel, and assessment developments.
Free and paid membership
Free readers receive the headline market signal, key charts, selected property analysis, and the public-record watchlist.
Paid members receive every weekly edition in full, including adjusted comparable sales and model diagnostics; a monthly State of Greenwich deep dive; the complete paid archive; methodology notes; and subscriber-only updates as new markets launch.
During the launch period, the live Greenwich dashboard is open to every reader. Paid membership supports the research and unlocks the deepest analysis in each edition.
How we work
The Address Index draws on Connecticut transaction records, Greenwich assessor records, statewide parcel data, official market reports, Census geocoding, and Town planning records. We preserve source links, distinguish proposals from approvals, and label modeled estimates separately from completed transaction evidence.
We do not republish listing photographs or brokerage descriptions. Public records cannot see interior finish, views, privacy, unrecorded renovations, deferred maintenance, buyer concessions, or private sale terms. Our models are market-intelligence tools—not appraisals.
Independence
The Address Index is not a brokerage, listing service, appraisal, or legal, tax, or investment adviser. Sponsorships, if introduced, will be clearly disclosed and will never determine editorial ranking.
