Jonathan Miller is stepping down from Douglas Elliman after more than three decades with the firm. The appraiser and author of the brokerage’s market reports said the Feb. 12 Elliman study will be his final report, concluding a 32-year tenure as the company moves to develop its own internal data capabilities.
Miller said he is shifting his focus to StreetMatrix, a neighborhood-level housing data venture he co-founded last year, while Elliman moves to develop an internal report program for agents and consumers.
In an email to colleagues, Miller wrote that he had spent “48 percent of my life” producing the Elliman reports and stressed that the series “approached each housing market as a research project, not as a marketing brochure.” He added that the brokerage had told him it was “already working hard” on a replacement for the report series. As reported by The Real Deal, Elliman CEO Michael Liebowitz told agents in an internal note that the firm would launch a new data-report program.
Miller's Next Move: StreetMatrix
Miller will now concentrate on StreetMatrix, which he launched with economist Nick Huntington-Klein to deliver neighborhood-level housing analytics broken down by bedroom count and micro-market. The venture was unveiled last September and has already rolled out statewide coverage starting in California, per a post on Housing Notes. Miller says the aim is to create a neutral benchmark that helps market participants make more informed decisions.
How StreetMatrix Works
The index is built from recorded sales, multiple-listing data and public records and measures price, supply, transaction counts and days on market to trace market performance at a granular level. Its creators emphasize that the tool is meant to measure micro-market behavior rather than produce automated home valuations. Those technical and rollout details were described in a September profile in The Real Deal.
Why Elliman Is Building In-House Reports
Bringing reporting in-house would keep market narrative and analytics under the brokerage’s brand, a shift that lines up with other recent strategic changes at Elliman. Industry coverage has documented executive reshuffles and business rationalizations as the firm refocuses operations, according to HousingWire. For agents and local outlets accustomed to the Elliman-Miller reports, the change raises questions about independence and how future data will be packaged.
Miller has said he will continue publishing independent market analysis while focusing primarily on StreetMatrix, which is already releasing state-level reports and plans monthly updates as it grows. The change marks the end of the Elliman-branded market series and introduces a comparison between an independent index and a brokerage’s internal research, according to Housing Notes. Neither Elliman nor Miller provided additional details on licensing, pricing, or any long-term collaboration at the time of publication.
