Why Portland Home-Price Numbers Disagree: A 2026 Metric Guide
Three Portland price figures sit near $525,000, but they measure modeled values, closed sales and asking prices for different populations and periods.

Portland price-metric definition table · 3 published metric observations.
A Portland housing search can produce several credible price numbers at once. On September 29, 2026, three widely used public sources each showed a citywide figure near $525,000:
| Source and measure | Published figure | Period | What it measures |
|---|---|---|---|
| Zillow Home Value Index | $527,359 | August 31, 2026 | Modeled typical home value across the housing stock |
| Redfin median sale price | $524,653 | Three months ending August 2026 | Median final price among homes that sold |
| Realtor.com median listing price | $525,000 | Charts through August 2026 | Median asking price among listed homes |
The figures are numerically close. That does not make them interchangeable. Their populations, methods and time windows differ.
The apparent agreement is only a snapshot
The largest gap among the three headline numbers is $2,706, or about 0.5% of the Redfin median. It would be easy to present that as three sources confirming one Portland market price. That conclusion would overstate the evidence.
Zillow's Portland page says the Zillow Home Value Index, or ZHVI, measures monthly changes in property-level Zestimates. Zillow describes it as a typical value measure across a broad housing stock. It is not limited to homes that sold during August.
Redfin's Portland market page reports a median final sale price for completed transactions. Redfin's current methodology says its displayed market metrics use rolling three-month periods to reduce monthly noise. The mix of homes that happened to sell can affect a transaction median.
Realtor.com's Portland market page reports a median listing price from its MLS-listed for-sale database. A listing median describes seller asking prices in the covered inventory, not the amount buyers ultimately paid.
One source can show stable values while another shows lower sale prices
The same snapshot reports a 0.3% year-over-year increase in Zillow's typical home value and a 3.6% year-over-year decrease in Redfin's median sale price. Those statements are not necessarily contradictory. A value index is designed to control for changes in the homes represented. A sold-home median can move when the mix of completed sales changes, even if individual homes do not all change by the same percentage.
Realtor.com reports its listing median down 0.95% year over year. That is a third signal, based on asking inventory. It can be useful for understanding what sellers are bringing to market, but it does not establish a closed-sale trend or the value of an individual home.
Match the number to the decision
Use a modeled value index when the question is how a provider estimates changes across the broader housing stock. Use a sale-price series when the question is what closed transactions in a defined period looked like. Use listing-price data when the question concerns the asking inventory buyers could see.
For an offer or list-price decision, none of these citywide numbers replaces property-level evidence. Compare recent genuinely similar homes, document condition and improvements, confirm the exact location and property form, and separate active competition from completed sales.
The property's value is not established by taking the average of three public headline figures. That would combine different measures without a defensible weighting rule.
A repeatable comparison checklist
Before quoting a market number, record:
- the geography, including whether it is Portland city, Multnomah County or the Portland metro;
- whether the population is all homes, listed homes, pending homes or closed sales;
- whether the number is a median, average, index or ratio;
- the exact month or rolling window;
- the property types included;
- whether the historical series can be revised; and
- the source retrieval date.
Then compare only like with like. A year-over-year Redfin sale-price change should be compared with the same Redfin geography and measure, not with a Zillow value-index change or a Realtor.com listing-price change.
What this study does not show
This three-observation comparison does not estimate an individual property's value, prove appreciation, predict a future price, or describe every Portland neighborhood. The source pages may revise historical values as their coverage and methods change. The downloadable table preserves what was read on September 29, 2026.
