Notices arrive in waves, in different formats, with short windows.
Every county prints a different notice
HCAD, Cook County townships, Maricopa and Florida TRIM notices place value, class and deadline in different spots. Analysts re-key all of it.
Record errors hide in plain sight
Wrong building area, a stale year built or the wrong class quietly inflate value. Few teams compare the roll to the rent roll line by line.
Triage is gut feel
With hundreds of notices and a 30-day window, firms file on the biggest increases and miss the parcels with the best evidence.

OCR and field mapping
Notice PDFs and scans are read with county-specific templates. Account number, owner, situs, noticed value, prior value, class and the protest deadline are extracted with a confidence score per field.

Roll reconciliation
We pull the assessor's characteristics for the parcel and compare them to your rent roll and building data. Conflicts (rentable area, year built, land area, class) are flagged for correction.
- 3
Three-approach benchmark
Value per square foot is tested against verified sales, a quick income capitalization from your last operating statement, and the median assessment of peer parcels.
- 4
Over-assessment score
Each parcel gets an over-assessment percentage, a likelihood rating and an estimated annual tax saving, sorted against the statutory deadline.
Assessment Audit questions
Next module: Income ValuationWhich notice formats can the OCR read?
Native PDFs, scanned PDFs and phone photos of mailed notices for every county with a jurisdiction hub. Unknown formats fall back to a generic extractor and an analyst confirmation step.
Can I score parcels without uploading a notice?
Yes. Enter a PIN, APN or account number and ATALI ELECTRIC pulls the current roll value for supported counties.
What does the likelihood rating mean?
It combines the size of the indicated over-assessment with how many approaches agree. High means at least two approaches indicate a value 12% or more below the notice.
Stop overpaying commercial property tax on a flawed mass appraisal.
