Beyond the Median is officially published!

I’m pleased to announce that my new book is available:

Beyond the Median: How to Unmask the Multi-Million Dollar Appeals Tsunami in Modern Mass Appraisal

Today marks a critical shift in how we evaluate, audit, and defend property tax assessment rolls.

For decades, assessing offices and valuation professionals have taken shelter behind a single statistical shield: aggregate central tendency. As long as median ratios hover near 1.00 and overall Coefficients of Dispersion (COD) meet basic benchmarks, assessment rolls are certified as compliant.

The uncomfortable truth? A healthy median is often a dangerous illusion.

Beneath smooth aggregate averages, traditional single-entry CAMA models (a sales-based approach that generates Just Values across the entire Tentative Roll with limited population-level checks and balances) routinely embed a silent, structural "double whammy":

1.   Severe over-assessment concentrated on entry-level and lower-value homes—triggering an uncontrollable tsunami of tax appeals and Value Adjustment Board petitions.

2.   Massive under-assessment on luxury and high-end assets—allowing billions in baseline property tax wealth to vanish untaxed.

What You Will Learn in Beyond the Median

This book moves past surface-level metrics to deliver an immediately usable, mathematically defensible, non-black-box solution that requires zero changes to existing CAMA software:

· The Double-Entry Mass Appraisal (DEMA™) Framework: A practical two-step population calibration model to audit and equalize values outside legacy software.

· The Ten Commandments of Valuation Modeling: A complete specification protocol enforcing strict data sanity, dual variable governance, simultaneous time parameterization, and formal OLS assumption testing for true BLUE status.

· Extended Percentile Audits & Champ-Challenger Diagnostics: How to use 10th-to-90th percentile audits to identify hidden tail skewness and pit legacy CAMA models ("the Champ") against population-calibrated econometric engines ("the Challenger").

TOMORROW: The wait is over.

For years, the mass appraisal and property tax industry has relied on a dangerous assumption: If the median ratio looks good, the assessment roll is fair.

Tomorrow, we shatter that illusion.

Beyond the Median: How to Unmask the Multi-Million Dollar Appeals Tsunami in Modern Mass Appraisal officially goes live tomorrow, Sunday, August 2nd!

In this book, we step beyond aggregate central tendency to expose the silent "double whammy" hidden inside traditional single-entry CAMA models—where lower-value homes face systemic over-assessment while luxury assets carry massive untaxed cushions.

More importantly, this volume delivers an immediately actionable, non-black-box solution:

·   The Double-Entry Mass Appraisal (DEMA™) Framework

·   The Ten Commandments of Valuation Modeling

·   Extended Percentile Ratio Auditing & Champ-Challenger Diagnostics

Whether you are a chief appraiser, assessment analyst, appeal attorney, mass appeal consultant, or public finance official, this playbook gives you the tools to unmask roll distortions, restore constitutional equity, and stop tax appeal waves before they start.
