Two non-interchangeable observations set the central tension in this market: Zillow’s June 2026 ZIP ZORI is $2,242, while Redfin’s direct rolling-three-month ZIP resale observation through June 30, 2026 reports a $1,044,764 median sold price. It places a typical blended asking-rent index beside a resale statistic, not rent and sale outcomes for the same property. The contrast is decision-useful because it prevents either series from being used as a substitute for the other, and it frames the later affordability and history evidence without turning the arithmetic into property-level financial performance.
Geographic scope is essential. The five-digit label 98116 is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow ZORI is a typical observed asking-rent index blended across rental types, rather than a lease quote, a unit-level comparable, or an average of only one housing form. For wider context, the Seattle city context rent is $2,224, the King County context rent is $2,330, and the Seattle–Tacoma–Bellevue, WA metro context rent is $2,269. Those city, county, and metro values are wider-area context only, not replacements for the ZIP index.
The backward-looking history puts the current asking index on a mixed path. Exact same-month Zillow ZORI change was 3.61% over 1 year, 3.04% annualized over 3 years, and 5.45% annualized over 5 years. The recent direction therefore confirms an upward move versus the three-year pace, yet breaks from the faster five-year path rather than matching it. History coverage is 100%. Its 2.96% annualized monthly-return variability says prior index changes did not move in a constant line, limiting the confidence due to any single current rent snapshot as a fixed reference. Separately, the 12.05% maximum drawdown records a meaningful historical reversal. Transparent national discovery ranks are 849 for momentum, 1,560 for stability, and 941 for balanced performance among history-eligible ZIPs, where lower ranks place higher. These are measurements, not forecasts or investment recommendations.
Different source universes explain why rent figures should not be collapsed into one number. The matched Census ZCTA’s ACS 2024 five-year survey reports $2,075 median gross rent for occupied renter homes, including selected utilities; the current Zillow asking-rent index is 8.05% higher. This ACS statistic is a survey median of occupied homes, not a current asking-rent series. By contrast, the FY2026 HUD two-bedroom FMR is $2,501, an administrative bedroom-specific standard rather than asking rent. Scaling ZIP ZORI with the local HUD ladder produces modelled estimates of $1,859 for a studio, $1,924 for one bedroom, $2,242 for two bedrooms, $2,933 for three bedrooms, and $3,449 for four bedrooms. These are modelled estimates, never measured bedroom rents.
The affordability screen is arithmetically less severe than the burden result, which is an important distinction. Applying the 30% screen to the current ZIP asking index produces required annual income of $89,680. The matched ACS ZCTA median household income is $126,151, so annualized ZORI equals 21.33% of that median. That threshold calculation is arithmetic, not advice and not an applicant qualification rule. In the ACS burden measure, 41.30% of renter households are at or above the threshold. Income and burden are five-year survey estimates, while ZORI is an asking-rent index; neither statistic identifies a specific household’s income, lease terms, or rent burden.
Housing-stock and vacancy measures add a different ACS ZCTA view. The survey estimates 15,073 housing units and a 6.78% vacancy rate. The stock spans single-family and large-multifamily structures, reinforcing that Zillow’s blended index is not a unit-type quote. Of the vacant categories, 204 units are classified as vacant for rent. That category does not reveal contemporaneous availability, unit condition, asking price, or lease terms; likewise, an area vacancy rate or burden percentage cannot prove anything about a particular unit.
The for-sale evidence challenges a simple inference from rent history or the income screen. In Redfin’s direct rolling-three-month ZIP resale observation, the median sold price gained 8.83% from a year earlier; 139 homes sold and median marketing time was 7 days. Inventory was 65 homes, equivalent to 1.4 months of supply. Sale-to-list signals stay in that resale universe: the average was 101.54%, 35.59% of homes sold above list, and 67.35% left the market in Redfin’s rapid-off-market window. The sale-price change outpaced the current asking-rent change, so no rent-screen reading can act as a proxy for property pricing. The 2.58% calculation—annualized ZIP ZORI divided by median price—is only a cross-source screening ratio and has no property-level performance interpretation. None of these observations predicts later rents, prices, or transactions.
Several limits remain before these aggregates can be applied to an address. Zillow, ACS, HUD, and Redfin use different source populations, definitions, and reporting windows; ZIP and ZCTA labels match here but their underlying geography and measurement purpose still differ. Concrete property-level checks are the unit’s dated advertised asking rent, bedroom count, included utilities, lease length, concessions, physical condition, and actual availability. For a sale comparison, examine the address-level list history, recorded sale result, marketing exposure, condition, and whether it is comparable to the subject rather than treating the ZIP median as a valuation. These checks do not turn aggregate vacancy, burden, HUD standards, or the screening ratio into proof. Does the address-level evidence actually match the source definition being used?
