Building on the launch of Session 1 (Representative Sales Sampling), we are taking a progressive, hands-on approach to valuation modeling across the next four sessions of our Substack & Patreon series.
Sessions
2–5 move from Basic → Intermediate → Advanced → Sophisticated model-building.
Why this
progressive roadmap?
Valuation
modeling shouldn't be an all-or-nothing jump into black-box algorithms. By
stepping sequentially from foundational linear regressions to sophisticated
econometric guardrails, newcomers learn not just how to specify models,
but why each layer of complexity is introduced to ensure statutory
assessment uniformity.
The
core methodology stays uniform across all four (OLS regression, Months-Since
time adjustment, location dummies, 2-Pass iteration, Z-score outlier protocol,
and full diagnostics aimed at BLUE status). What changes is the complexity of
the data and variables — giving newcomers a clear on-ramp while still
delivering advanced techniques for experienced analysts and consultants.
Session
2 (Basic Modeling) drops next.
Sessions 2–5 are available to paid subscribers (Executive Summary is free).
Session
1 remains 100% free
to read.
