At 97124, the distinctive decision question is how to read a current asking-rent benchmark that has softened while other rent series describe different populations and purposes. Zillow’s June 2026 ZORI is $1,859 per month, a 4.2% decline from a year earlier. It is a ZIP-level typical observed asking-rent index blended across rental types, so it frames current asking-market conditions rather than a guaranteed quote for any dwelling. The five-digit label is both Zillow’s ZIP market identifier and a Census ZCTA match. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP, a distinction that matters when assessing whether a particular address is in scope.
Bedrooms supply a more usable comparison, but not a measured rent schedule. Scaling the ZIP ZORI through the local HUD bedroom ladder yields modelled estimates of $1,519 for a studio, $1,622 for one bedroom, $1,859 for two bedrooms, $2,533 for three bedrooms, and $3,007 for four bedrooms each month. The increase is uneven because it follows the HUD ladder rather than a fitted set of local listing medians. These are modelled estimates, never measured bedroom rents: a property may price differently according to condition, lease terms, utility treatment, availability, or other unreported attributes. Their purpose is to make bedroom comparisons internally consistent with the all-type ZIP ZORI.
On a simple annualized calculation, the benchmark corresponds to $74,360 in household income for the 30% required-income screen. That screen is arithmetic, not advice and not an applicant qualification rule. The matched ZCTA’s median household income is $110,067, making the benchmark 20.3% of that median on the same arithmetic basis; the median is not a measure of prospective renters’ income. Of 21,478 occupied homes, 11,473 are renter occupied, a 53.4% renter share. Within the observed renter universe, 4,869 households, or 42.4%, reported gross-rent burdens at or above the screen in the ACS 2024 five-year survey. That burden is a population-level observation, not evidence about a particular household or unit.
The current index should not be merged with ACS or HUD. The ACS median gross rent is $2,018 and has a published ACS margin of error; it comes from a five-year survey of occupied renter homes, not asking listings, and gross rent includes selected utilities. Zillow’s level is 7.9% below that ACS median, but the difference does not establish a market movement because the universes, timing, and rent definitions differ. Separately, the FY2026 local HUD two-bedroom FMR/SAFMR standard is $1,922, putting ZORI 3.3% below it. HUD FMR/SAFMR is an administrative, bedroom-specific standard, not asking rent, so it neither confirms an available unit’s price nor substitutes for the Zillow or ACS measure.
Inventory data describe the matched ZCTA’s stock rather than live listings. It has 22,192 housing units, of which 21,478 are occupied and 714 are vacant, for a 3.2% all-unit vacancy rate. Reported vacant categories include 270 units for rent and 75 for sale, while other vacancy categories account for the balance. The structure mix includes 12,648 single-family units and 4,129 units in large multifamily structures. This composition clarifies the stock represented in the area-level survey, but the for-rent vacancy count is not proof that a specific dwelling is vacant, advertised, attainable, or offered at the ZORI level.
Broader benchmarks set context but are not replacements for ZIP evidence. Hillsboro city context shows typical asking rent of about $1,902, Washington County context shows $1,911, and Portland-Vancouver-Hillsboro, OR-WA metro context shows $1,805; the ZIP benchmark is below the city and county context and above the metro context. Hillsboro city context has a 46.1% observed burden share, while Washington County context has a 49.3% observed burden share. The metro context’s 6.4% apartment vacancy rate is a rental-segment metric, unlike the ZCTA’s all-unit vacancy measure, so the two should not be treated as interchangeable. These comparisons establish relative scale only and do not transfer city, county, or metro conditions to a ZIP address.
Key limits are temporal, geographic, and definitional. ZORI is an index rather than a menu of available apartments; ACS is a surveyed, multi-year description with sampling uncertainty; and HUD standards serve an administrative function. None can identify the rent, bedroom classification, or utility package for a particular property. Concrete property-level checks are the advertised base rent, bedroom count, included and excluded utilities, recurring and nonrecurring charges, concession conditions and expiration, lease length, availability date, occupancy restrictions, and the property address’s fit with the relevant ZIP and ZCTA geography. Confirming whether the quoted unit is comparable with the rental type embedded in ZORI preserves separation between the market index, household survey, and administrative standard.
