Why This Matters for Operators

Property questions land on operators constantly - what a site is worth, what comparable assets actually traded for, whether a market is liquid, who owns the parcel next door, whether an auction lot that keeps failing is a bargain or a repricing problem. Each of those questions used to mean a different subscription, a spreadsheet of manual lookups, or a broker on the phone.

MarketCode compresses all of it into one agent-callable endpoint with an unusual level of analytical honesty. Every market row carries a tx_decision flag stating whether the price behind it is direct, modeled, suppressed, imputed or missing - so an agent can tell you when a figure is a measurement and when it is a borrowed prior. That distinction is the difference between quoting a real comp and inventing one.

Business Relevance

  • Investors and asset managers get valuations, comps and liquidity rankings with the evidence level stated per cell, instead of a flat number
  • Agencies and developers source long-held, high-equity owners who never come to market, with title boundaries as GeoJSON
  • Property operators reconcile EPC, Rightmove, council tax and OS data divergences in one call
  • Auction buyers read achieved hammer prices against the AVM to see how far below market a lot cleared

Integration with CorpusIQ

MarketCode is the UK-property analogue of what CorpusIQ does for business financials - it turns a registry of record into queryable, agent-ready answers. An agent running CorpusIQ connectors for a UK property business can pair QuickBooks or Stripe revenue with MarketCode's market rankings to test whether portfolio turnover matches district liquidity, or join HMLR ownership lookups to deal flow tracked in HubSpot. The composed workflow is: CorpusIQ reads the business, MarketCode reads the market, and the agent reconciles the two.

Limitations

  • UK only; England and Wales coverage is deepest, with some tools excluded for Scotland and Northern Ireland
  • Credit-based pricing on several core tools (8-10 credits per resolution call)
  • Brand new listing with no track record yet
  • Some market metrics (rental value, gross yield, days on market) are declared not yet backfilled and return null by design
