Everything you need to know about our county ownership intelligence reports, data sources, CSV format, and purchasing process.
It is a systematic analysis of county assessor parcel records that identifies ownership concentration clusters — addresses where three or more distinct entities (LLCs, corporations, trusts) share the same owner mailing address. The report maps these clusters, scores them by concentration density, and delivers the findings as a professional PDF with a companion searchable CSV.
Each report includes a 150-200 page PDF with executive dashboard, geographic treemap, scatter analysis, municipality breakdown, top 25 concentration clusters by two ranking methods, entity rosters for the top 100 clusters, CSV Quick-Start Guide, full methodology, and legal disclaimer. You also receive a companion CSV file with every entity in every cluster for the entire county.
St. Louis County, Missouri is our first available report. Additional Missouri counties including St. Charles County and Jackson County are in development. Join our waitlist at nexus.info@convergence-data-analytics.com to be notified when new counties are released.
All data is sourced exclusively from publicly available county assessor parcel records. For St. Louis County, the data comes from the St. Louis County Assessor's office via the ArcGIS Hub open data portal. We do not use proprietary, classified, or non-public data sources.
Reports reflect the most recent county assessor data available at the time of generation. The St. Louis County report is based on the current tax year assessor extract. We update reports as new assessor data becomes available — typically annually when counties publish updated parcel records. The data currency date is printed on the cover of every report.
The concentration index is a composite score that measures the density and complexity of ownership patterns at a single mailing address. It starts with the number of distinct entity names at the address, then adds bonuses for factors like out-of-state ownership, high distress scores, high appraised value, and quitclaim deed patterns. Higher scores indicate greater concentration — not wrongdoing. The full formula is documented in every report and on our methodology page.
The distress score (0-100) is assigned to individual parcels based on measurable property characteristics: absentee ownership, vacant land, low improvement ratio, long ownership tenure, pre-1950 construction, low assessed value, large lot size, and multi-family absentee ownership. These are data-driven signals, not conclusions — a high distress score means the property exhibits multiple characteristics commonly associated with distressed or underperforming assets.
The CSV is a standard comma-separated values file compatible with Microsoft Excel, Google Sheets, Apple Numbers, Power BI, Tableau, and any database tool. It contains 16 columns: Cluster ID, Cluster Address, City, State, Entity Count, Parcel Count, Risk Score, Total Appraised Value, Entity Name, Locator, Property Address, Property Class, Appraised Value, Owner State, Distress Score, and Deed Type. Each row represents one entity-parcel combination.
The St. Louis County CSV contains 50,809 rows across 4,934 clusters. Row count varies by county based on the number of identified clusters and entities.
Yes. Open Excel, go to File → Open, select the CSV file, and Excel will automatically parse the columns. We include a CSV Quick-Start Guide in every report with recommended pivot table setups and filter workflows for immediate analysis.
Reports are delivered as instant digital downloads via Gumroad. After purchase, you receive immediate access to download both the PDF report and the companion CSV file.
We offer a 14-day refund from the date of purchase for material factual errors in the report data. A material factual error is defined as an incorrect parcel locator number, an entity attributed to the wrong ownership cluster, or a property incorrectly assigned to the wrong mailing address group. Refund requests must identify the specific error and be submitted to nexus.info@convergence-data-analytics.com within 14 days of purchase. Refunds are not available for dissatisfaction with the scope, volume, or conclusions of the report. Full terms at our Terms of Service page.
No. The presence of multiple entities at a single address is a common and lawful business practice. Many real estate investors, property managers, and law firms operate multiple LLCs from the same office for legitimate reasons including asset protection, liability isolation, and portfolio management. Our reports identify concentration patterns that may warrant further due diligence — they do not imply wrongdoing or illegal activity by any named entity.
