A research publication with its working shown

Propstock publishes prime residential market readings and the coverage around them. What separates it from a data terminal is that every figure arrives with its sources, its vintage and its confidence attached.

What Propstock is

Propstock tracks prime residential values across 30 markets through 30 city desks, and publishes the Prime Index, city intelligence, development coverage and quarterly research. There are currently 288 published articles and 1 report.

The readings are compiled from published sources rather than licensed from a data vendor. That is a real constraint and the site is built around admitting it: where there is no citable figure, a page shows a dash instead of an estimate, and the global composite refuses to publish when too few cities are reporting, stating how many are in.

What Propstock is not

  • Not a broker. We do not transact, take commission on a sale, or represent a seller.
  • Not an adviser. Nothing here is investment advice, and no figure on the site is a valuation of a specific property.
  • Not a listings portal. Developments are covered where a desk judges them worth covering, and a listing is never created automatically from a submission.
  • Not a data vendor. Our figures are compiled from public material, and we tell you which material.

Why the method is public

Presenting compiled figures with the visual authority of a terminal only earns that authority if a reader can find out how the numbers are made. So the process is published in full, including the parts that are automated and the parts that are weakest.

The first pass of compilation is done by a language model with web search, and the site says so plainly. Nothing it produces is publicly visible until a person publishes it. Uncited figures are discarded rather than published with a caveat. Coverage drafted by the research engine carries a disclosure and is bylined to a desk, and the software refuses to attach a named human byline until a human has reviewed it.

The detail, including what our confidence grades mean and what a bureau actually is, is on methodology. The commitments we hold ourselves to are on editorial standards.

How it is paid for

Propstock is funded by advertising, research underwriting and paid access to some reports. Advertisers get no input into readings, coverage or a developer’s verification status, and advertiser content is always labelled as such. The boundary is set out on advertise.
