Resale pricing sets the central tension for 98105. Zillow ZORI for June 2026 is $2,073 monthly, a typical observed asking-rent index blended across rental types rather than a lease quote or a bedroom-specific measurement. The ZIP label 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. That distinction matters when connecting this asking index with survey results, administrative standards, or a property address. The current reading is a market snapshot in its own evidence universe, not a universal price applicable to every available unit.
Backward-looking ZORI history supports slow, persistent growth but not uninterrupted rises. Exact same-month annualized changes were 0.58% over 1 year, 1.18% across 3 years, and 3.66% over 5 years. The recent direction therefore confirms the longer positive path, but at a slower pace than the extended record. The annualized variability calculated from monthly returns is 2.60%, so ordinary observed changes have been relatively constrained and a single current snapshot carries more confidence than it would in a highly erratic series. Separately, maximum drawdown reached 8.87%, showing that contained routine variation does not rule out a meaningful retreat from an earlier high. Coverage is 100%. Transparent national discovery ranks among history-eligible ZIPs are 2,081 for momentum, 878 for stability, and 1,705 for the balanced measure; lower ranks are higher. These are descriptive backward-looking measurements, not forecasts or investment recommendations.
Scope differences explain why the current index should not substitute for survey or program values. In the matched ZCTA, the ACS 2024 5-year survey reports a $1,849 median gross rent for occupied renter homes; that measure includes selected utilities. It sits 12.1% below the asking index, a difference that neither proves rent movement nor supplies a quote for a particular unit. The local FY2026 HUD two-bedroom FMR/SAFMR standard is $2,501, and the asking index is 17.1% below it. HUD’s administrative, bedroom-specific standard is not asking rent, while ACS gross rent is a survey median rather than a market availability measure. The sources answer different questions even though they share the ZCTA or ZIP label.
Size-oriented figures should be read differently again. The bedroom ladder scales the ZIP asking index using local HUD relationships, producing modelled monthly estimates of $1,719 for a studio, $1,779 for one bedroom, $2,073 for two, $2,712 for three, and $3,189 for four. They are modelled estimates, never measured bedroom rents, and they do not establish that units of those sizes were offered or leased at those amounts. The local HUD ladder supplies the relative pattern, but HUD FMR/SAFMR remains an administrative standard rather than an asking-rent survey. In particular, the match between the two-bedroom model and the all-types index is a scaling result, not validation through unit-level observations.
Affordability arithmetic is a separate screen, and neither advice nor an applicant qualification rule. Applying the 30% convention to the monthly asking index produces a required annual income of $82,920. The matched ZCTA’s ACS median household income is $74,349; it describes area households, not an applicant or a renter-income distribution. In the same survey, 58.4% of occupied renter households reported paying at least 30% of income toward rent, evidence of area-level burden rather than proof about any particular household or unit. Housing stock totals 21,251 units, with an 11.7% vacancy rate and 1,465 units classified vacant for rent. Renters account for 68.6% of occupied homes, and the stock contains more large multifamily units than single-family units. Vacancy classification does not demonstrate present availability, condition, price, or lease terms for a specified home.
Wider geographies provide comparison rather than replacement evidence. The City of Seattle 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; all are above the ZIP asking index. The City of Seattle, King County, and metro figures have broader geographic scope than the ZIP’s ZORI and cannot substitute for it. They do show that the ZIP’s current index sits below each named contextual rent benchmark, but they do not reveal whether the rental mix, utilities, or observed listing terms align. Treat the comparison as a scope-labelled reference point rather than evidence about a particular building, tenant, or advertised unit.
The direct rolling 3-month ZIP resale observation stays wholly in the for-sale universe. Its median sold price was $1,299,706, up 1.86% year over year; 100 homes sold, median marketing time was 11 days, inventory was 76 homes, and months of supply stood at 2.3. The average sale-to-list result was 99.6%, while 25.8% of sold homes closed above list. These are resale liquidity and pricing signals, not rental transactions, rent comparables, or property economics. Dividing annualized ZIP ZORI by the median sold price gives a 1.91% cross-source screening ratio only; it is not a cap rate, net return, expected return, or property yield. Sale prices rose faster than the latest asking-rent history, challenging a simple reading of the stable-growth rent path and the income screen.
Decision use is limited by timing, aggregation, and source design. ZORI cannot reveal the actual asking rent, concessions, utilities, size, condition, occupancy, or lease terms of a candidate unit; ACS cannot identify a live listing; HUD cannot price one lease; and Redfin cannot evidence rental activity. Concrete property-level checks include confirming that an address maps to the intended Zillow ZIP market and Census ZCTA, recording the advertised rent and all utility obligations, verifying bedroom count and available date, and comparing relevant closed-sale details with the resale observation’s definitions. Also test whether a vacancy is truly rentable rather than merely classified vacant, and whether a listed sale is comparable in date and property characteristics. No source here forecasts rents, sale prices, occupancy, or outcomes. Does the verified property evidence support the purpose of the screen without treating its broad measures as promises?
