Cook County Specific Pipeline

Cook County appeal intake automation —
estimates in seconds.

Automate multi-PIN intake with deterministic assessment selection (Board > Certified > Mailed) and instant tax rate/equalization extraction. Export complete job packets without spreadsheets.

Enforces Board > Certified > Mailed
Validates tax rate & equalization
dcrt-engine/process_intake.sh

Escape the spreadsheet grind.

Manual compilation leaves your firm exposed to simple math errors and wastes hours of high-value partner time.

The Old Way

  • Manual assessor lookup line by line
  • Confusion on which assessment value is final
  • Ctrl+F searching through PDF rate tables
  • Copy/paste math prone to transcription errors
  • Slow turnaround for client intake estimates
  • Siloed data that needs re-entry for billing

The DCRT Way

  • Instant multi-PIN bulk data ingestion
  • Deterministically picks Board > Certified > Mailed
  • Finds most recent tax code rate (through 2024)
  • Automatically applies the latest equalization factor
  • Generates a clean PDF for the client
  • Outputs a CSV job packet for ops & billing

How it works

Three simple steps to generate complete intake packets.

1

Paste PINs

Paste one or many PINs, with or without dashes. Our parser handles the cleaning automatically.

2

Automated Pull

DCRT pools the data, selects correct assessment tier, and pulls the exact tax code rate table data.

3

Download Packet

Receive a client-ready PDF report along with a structured CSV export packet for ops and billing.

"Designed as an internal intake tool for Cook County appeal firms."

Built like infrastructure.

Stop worrying about manual lookups. Our deterministic logic handles the edge cases.

Multi-PIN Batch Intake

Scales your intake volume. Process entire portfolios instantly without worrying about formatting dashes.

Assessment Hierarchy Logic

Eliminates ambiguity. Deterministically selects Board > Certified > Mailed assessments automatically.

Smart Year Selection

Auto-calibrates to use the most recent assessment year available without manual toggling.

Automated Rate Tables

Eliminates manual reconciliation. Looks up the exact tax rate from embedded rates and displays the year used.

Equalization Included

Ensures accuracy. State equalization factors are automatically retrieved and mathematically applied.

Portfolio Summary

Delivers clear client communication through summary cover pages and per-PIN narrative breakdowns.

CSV/JSON Export Packets

Accelerates operations mapping outputs directly into your firm's billing or case management systems.

Verification Harness

Audit-friendly transparency. Every run produces a PASS/FAIL output file so you never guess about math integrity.

Built for Cook County.

Reduce operational risk with transparent, deterministic logic.

Eliminate Random Software Risk

  • Deterministic selection logic: No guessing. The rules engine follows exact assessor tiering.
  • Output includes source labels: Every report explicitly states the assessment source and rate year used.
  • Math consistency validation: Every run generates a PASS/FAIL file to prove outputs sum correctly.

Frequently Asked Questions

We utilize official Cook County Assessor and portal APIs for assessment tier data, combined with explicitly curated county rate tables for the most accurate and recent tax rates and equalization factors.
DCRT uses a deterministic selection logic based on the Cook County appeal timeline: it checks for Board of Review Certified first, then Assessor Certified, and finally Assessor Mailed (Original).
The logic looks up the most recently available tax code rate (e.g., through 2024), pulls the required rate from the rate table, and prominently displays both the year used and the rate itself on the final report.
System logic and rate tables are maintained and updated annually as new equalization factors and tax rates are published by the county and state.
No, DCRT is designed purely as an internal intake and operations tool for your firm. However, the resulting PDF summary reports are formatted cleanly and are absolutely appropriate to share with your clients.
Yes. The multi-PIN batch ingestion handles large portfolios effortlessly, returning a unified portfolio summary, per-PIN breakdowns, and a single comprehensive CSV export packet.
The verification harness explicitly catches incomplete data or mathematical discontinuities. Those PINs are flagged gracefully rather than breaking the batch process, allowing your team to manually review only the exceptions.
It is delivered as an internal tool (often a local executable or internal web app) scoped explicitly to your firm's users.
