Why Portland Home-Price Numbers Disagree

Three citywide figures were within $2,706, but they measured a modeled value index, closed-sale prices and asking prices for different populations and periods.

Finding: Three citywide figures were within $2,706, but they measured a modeled value index, closed-sale prices and asking prices for different populations and periods.

Boundary: Portland city only. The comparison does not describe Multnomah County, the Portland metro, a neighborhood or an individual property.

Interpretation

The largest displayed-value gap is $2,706, about 0.5% of the Redfin figure. Numerical proximity does not prove that the measures estimate one common market price. Zillow's index covers the broader housing stock, Redfin's median covers completed sales, and Realtor.com's median covers asking inventory.

The year-over-year directions also differ. Preserve the provider, population and period rather than averaging the changes.

Method and limits

Values were transcribed from the named public pages on 2026-09-29. Derived differences use the displayed values without hidden precision. No provider supplied a record-level sample size on the cited city page, so sample size is recorded as not supplied. The table is a dated comparison, not a property valuation, forecast or complete market census. Historical values may be revised by the providers.
