Interpretation
The provider levels differ by $8, about 0.5% of Zillow's figure. Their year-over-year directions differ, which reinforces the need to preserve the source definition. Zillow's Portland value was $216, or about 11.1%, below its national value in the same snapshot.
None of these observations is a rent-versus-buy calculation. A household comparison needs exact financing, taxes, insurance, association costs, maintenance, concessions and expected occupancy.

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.
