Official Launch Announcement: 101 Key Terms for Valuation Modeling

Today I’m releasing a focused desktop reference built for the people who actually work with valuation models every day—assessors, AVM architects, CAMA modelers, review appraisers, assessment leaders, VAB members, and consultants.

101 Key Terms for Valuation Modeling: A Practical Desktop Reference for Mass Appraisal, CAMA, and AVM Practitioners

Each of the 101 core terms follows a clear three-part structure:

·        Definition

·        Application in Valuation Modeling

·        Practitioner’s Corner

Closely related concepts appear as split entries for quick comparison. The book also includes specialized appendices with VAB & courtroom defense scripts, forensic audit terms, proprietary diagnostics, and real estate finance terms—plus a full A–Z master index for fast lookup.

This one is designed to stay on your desk, not collect dust on a shelf.

Available now on Amazon (Kindle, Paperback, and Hardcover) and as a PDF on Payhip.

All proceeds support charities, including Save the Children.

Tomorrow, September 9th: The Official Release of 101 Key Terms for Valuation Modeling

In Computer-Assisted Mass Appraisal (CAMA) and Automated Valuation Modeling (AVM), precision isn't just an academic pursuit—it is a forensic necessity. When appraisers, software architects, assessment officials, and tax appeal experts speak different dialects, valuation models break, tax rolls become vulnerable, and appeals drag on unnecessarily.

Tomorrow, that ambiguity ends.

I am officially releasing my newest ~400-page (Paperback) canonized desk reference:

101 Key Terms for Valuation Modeling: A Practical Desktop Reference for Mass Appraisal, CAMA, and AVM Practitioners

Built to stay on your desk rather than collect dust on a shelf, this compendium bridges complex econometric theory with real-world roll development and defense.

Each of the 101 primary terms follows a consistent three-part structure:

·  Definition — a concise, authoritative explanation

·  Application in Valuation Modeling — how the concept operates inside CAMA and AVM systems

·  Practitioner’s Corner — actionable guidance, common pitfalls, and defense-oriented insights

Packed with twelve master thematic categories, comparative split entries (A/B/C), three specialized back-matter appendices (including forensic audit protocols and cross-examination scripts), and a Master A–Z Index, this book provides the exact vocabulary required to build, audit, and defend robust valuation models.

Available tomorrow, September 9^th, in Kindle, Paperback, and Hardcover on Amazon and as a PDF via Payhip.

As always, author royalties from my books support charitable organizations, including Save the Children.

Coming September 9th: 101 Key Terms for Valuation Modeling

On September 9th, I’m releasing a new desktop reference built for the people who actually work with valuation models every day.

101 Key Terms for Valuation Modeling: A Practical Desktop Reference for Mass Appraisal, CAMA, and AVM Practitioners

This one is designed to stay on your desk, not collect dust on a shelf.

Launching September 9th.

More details coming soon.

The momentum is building: Beyond the Median is officially live!

 Most Tentative Rolls look fine… until the appeals start.

The traditional one-step CAMA model generates Just Values across the entire roll using a sales-based approach — then stops. No further population-level checks. No systematic way to catch the hidden distortions that quietly build into multi-million dollar problems.

Beyond the Median was written to change that.

It shows assessing professionals, VAB members, and consultants how to:

·  Apply The Ten Commandments of Valuation Modeling as a practical code of practice

·  Use extended percentile analysis (10th–90th) to reveal what the median hides

·  Spot location-based and ownership-based inequity before the roll is finalized

·  Strengthen the Tentative Roll without waiting for a full system overhaul

This is not another theoretical modeling book. It is a practical field guide for people who have to defend the numbers.

Now available on Amazon (Kindle, Paperback, Hardcover) and Payhip (PDF).
