ZIP 98684 presents a current-rent level that is firmer than its very recent momentum. Zillow ZORI, a ZIP-level typical observed asking-rent index blended across rental types, is $1,942 and edged only 0.07% higher year over year. This is an asking-rent indicator, not a lease-price observation or a quote for any particular home. Against wider context only, the City of Vancouver context rent is $1,818, the Clark County context rent is $1,874, and the Portland-Vancouver-Hillsboro, OR-WA metro context rent is $1,805. Those city, county, and metro figures provide geographic context rather than substitutes for this ZIP’s direct rent index.
The historical record says the short period has cooled relative to the longer path. The exact same-month one-year (1-year) annualized Zillow rent change was 0.07%, versus 0.43% over three years (3-year) and 2.97% over five years (5-year). Thus, the latest direction breaks from, rather than confirms, the stronger five-year growth pace. Monthly-return variability was 2.43% annualized, which supports more confidence in the broad level of the current rent snapshot than in a claim of accelerating momentum. Separately, the maximum drawdown reached 4.20%, showing that the index has experienced meaningful declines despite its longer-run increase. History coverage is 100%; transparent national discovery ranks among history-eligible ZIPs were 2,355 for momentum, 569 for stability, and 1,747 for the balanced measure. These are backward-looking discovery measurements, not forecasts or investment recommendations.
Cross-source comparisons need careful boundaries. The matched Census ZCTA’s ACS 2024 five-year survey reports median gross rent of $1,918 with a $50 margin of error; this is a survey measure for occupied renter homes and includes selected utilities. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The Zillow asking-rent index is 1.3% above that ACS median, a narrow gap that does not make the two measures interchangeable. HUD’s local two-bedroom FMR/SAFMR standard is $1,922, also near ZORI, but HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent and not evidence of prevailing lease terms.
The bedroom view is a modelled estimate, not a set of measured bedroom rents. It scales the ZIP ZORI using the local HUD bedroom ladder, producing estimated monthly rents of $1,586 for a studio, $1,694 for one bedroom, $1,942 for two bedrooms, $2,646 for three bedrooms, and $3,141 for four bedrooms. This pattern is useful for keeping bedroom assumptions internally consistent with the area’s HUD standard. It should not be read as five observed ZIP rent averages, nor does it identify the asking rent, utility treatment, condition, or availability of a particular apartment or house.
The current index sits within a mixed affordability screen. The ZCTA’s median household income is $90,620, with a $3,770 margin of error. Applying a 30% income share mechanically to the ZIP asking-rent index produces required annual income of $77,680. That required-income screen is arithmetic only; it is neither advice nor an applicant qualification rule. The ACS burden measure adds an important separate lens: 3,276 renter households were reported as paying at least 30% of income toward rent, equal to 48.5% of surveyed renter households. This survey burden cannot establish what any one household pays or prove that a particular available unit is affordable.
The ACS ZCTA housing profile provides a structural backdrop rather than a live availability count. It contains 14,957 housing units, with 475 vacant units and a 3.2% vacancy rate. The stock includes 9,648 single-family units and 1,793 units in large multifamily structures, while the owner-renter mix has more owner-occupied than renter-occupied homes. Vacancy categories do not identify currently advertised rentals, lease-ready condition, or the price of vacant space. The City of Vancouver, Clark County, and metro comparisons above remain wider-geography context; they cannot replace the ZIP’s stock, vacancy, or rent measures.
Redfin supplies a separate direct rolling-three-month ZIP resale observation, not rental transactions. Its median sold price was $509,885, up 1.37% year over year, with 89 homes sold and median marketing time of 27 days. Redfin reported inventory of 96 homes and 3.2 months of supply. Sale-to-list signals were also firm: the average sale-to-list ratio was 100.5%, and 25.3% of sales closed above list. The annualized ZIP ZORI divided by Redfin’s median sold price is a 4.57% cross-source screening ratio only, not a cap rate, net return, expected return, or property yield. Resale pricing gains and above-list sales show a for-sale market signal that is stronger than the ZIP’s nearly flat one-year rent reading, challenging any claim that rent momentum and resale momentum are moving together.
Several limits remain material. Zillow’s blended asking-rent index does not reveal bedroom-specific lease transactions, ACS is a lagged five-year survey with sampling uncertainty, HUD is an administrative standard, and Redfin describes ZIP resale activity rather than rental economics. A property-level review would need to verify the actual bedroom count, current comparable asking rents, included utilities, lease term, concessions, condition, vacancy status, and whether the property’s sale evidence resembles the rolling ZIP resale data. The central unresolved question is whether a specific property’s current terms align with the modelled bedroom ladder and affordability screen without treating either as proof of its actual market rent.
","findings":[{"body":"The current Zillow asking-rent index is near the ACS median gross-rent survey result and the local HUD two-bedroom standard, but the one-year rent change is far slower than the five-year annualized pace.
