Turn raw property records into an interactive intelligence graph.
The CORTEX Real Estate Intelligence Pack is a domain-specific knowledge graph configuration for the CORTEX OSINT platform. It transforms scattered public property records, corporate filings, tax assessments, and permit data into a navigable, interactive intelligence graph that reveals hidden ownership structures, shell company networks, and investment opportunities.
This is not a database. It's a lens — a pre-configured intelligence schema that tells CORTEX how to recognize, classify, link, and visualize real estate entities and their relationships.
Property ownership is deliberately obscured. LLCs hold LLCs that hold trusts that hold properties. Beneficial owners hide behind registered agents. Tax liens accumulate across dozens of shell entities controlled by a single developer.
Traditional tools give you one record at a time. CORTEX gives you the entire network at once.
| Challenge | How CORTEX Solves It |
|---|---|
| Who really owns this property? | Trace ownership chains through LLCs, trusts, and nominees back to beneficial owners |
| Is this LLC a shell company? | Pattern detection: registered agent overlap, same-day formation, address clustering |
| Are these properties connected? | Entity resolution across deeds, mortgages, permits, and corporate filings |
| What liens exist across a portfolio? | Cross-entity lien aggregation — see total exposure, not just per-parcel |
| Is this a good investment? | Permit activity, zoning changes, comparable sales, and development pipeline in one graph |
| Is there fraud happening? | Straw buyer detection, title washing patterns, fraudulent conveyance indicators |

Import recent transactions → Fraud mode highlights: buyer formed LLC 3 days before closing, purchase price 40% below market, seller is a different LLC with the same registered agent, property immediately transferred to a third LLC. Pattern score: HIGH RISK.
Search the developer by name → CORTEX finds 8 LLCs → maps 23 properties across them → aggregates: $2.1M in mortgages, $340K in mechanic's liens, $89K in tax delinquencies, 2 active foreclosures. Total exposure: $2.53M.
