In-depth explorations of specific valuation challenges, market phenomena, regulatory impacts, and appraisal principles applied to the Portland and Vancouver Regions. Each deep dive uses cleaned RMLS data with careful segmentation by housing type (detached, condominiums, attached on owned land, manufactured on owned land)—never conflating distinct categories—to deliver precise, defensible insights.
Common topics include external/functional obsolescence, conformity, highest and best use, plottage in assemblies, tax mechanics (e.g., Measure 50), infrastructure constraints (e.g., sewer moratoriums), and demographic affordability barriers. These pieces bridge theory and real-world closed sales, offering practical guidance for agents, lenders, investors, attorneys, and homeowners navigating complex scenarios.
All data is rigorously cleaned from RMLS sources—for common challenges (misclassifications, incomplete fields, status anomalies, etc.) and mitigation steps, see: RMLS Data Challenges.
Useful for understanding how broad principles manifest locally in the Portland Region (six Oregon counties) and Vancouver Region (four Washington counties)—treated as distinct markets to avoid typical conflation.
