Appraiser-curated quarterly snapshots of residential market performance in the Portland and Vancouver Regions, using cleaned RMLS data. These updates track key metrics including median and average prices, sales volume, cumulative days on market (CDOM), inventory months of supply, absorption rates, and sale-to-list price ratios—with valuation-focused insights such as market condition adjustments, comparable selection challenges, and emerging trends in buyer/seller dynamics.
I treat the Portland Region (six Oregon counties: Clackamas, Columbia, Hood River, Multnomah, Washington, Yamhill) and Vancouver Region (four Washington counties: Clark, Cowlitz, Klickitat, Skamania) as distinct market areas to avoid the conflation common in official Portland–Vancouver–Hillsboro MSA reporting. This separation accounts for meaningful state-level differences in property taxation (Oregon’s Measure 50 vs. Washington’s levy system), disclosure requirements, regulatory environments, and data handling—all of which impact appraisal practice and trend analysis.
Primary focus remains the Portland Region six-county market area—see that page for full definition, county profiles, and appraisal context.
Vancouver Region coverage is emerging and will receive equivalent attention across all four defined counties.
These updates provide segment-specific clarity—carefully separating detached single-family homes, condominiums, attached housing on owned land, and manufactured homes on owned land—avoiding the common pitfall of conflating these distinct property types, which can distort trends, valuation accuracy, and appraisal reliability.
All data is rigorously cleaned from RMLS sources—for common challenges (misclassifications, incomplete fields, status anomalies, etc.) and mitigation steps, see: RMLS Data Challenges.
These regular updates provide quick, reliable context for real estate agents (pricing and listing decisions), lenders (risk monitoring), investors (timing), attorneys (valuation support), and homeowners (market awareness).

Vancouver Region Quarterly Updates – Coming Soon
