At the stated June 2026 endpoint, Zillow’s ZIP-level ZORI for 98118 is $2,017 per month. ZORI is a typical observed asking-rent index blended across rental types, so it is a market indicator rather than a lease-specific quote or a median for an individual building. The central reading is not simply rising rent: the ZIP’s asking-rent snapshot sits beside very active but separately measured resale evidence, while renter-burden data point in a different direction. Those records answer different questions, and their overlap should be treated as a screen rather than as proof about any particular home or lease.
Backward-looking ZORI history shows exact same-month gains of 3.03% over one year, 2.45% annualized over three years, and 4.56% annualized over five years. Recent direction therefore confirms the longer positive path relative to the three-year rate, but it does not match the stronger five-year pace. Monthly changes converted to annualized variability were 2.87%, indicating that one current reading has some short-run movement around it rather than being a fixed rent level. Separately, the largest historical peak-to-trough decline was 7.69%, a meaningful reminder that stable growth did not mean no declines. Coverage is 100%, and transparent national discovery ranks among history-eligible ZIPs were 1,115 for momentum, 1,379 for stability, and 1,089 for the balanced measure; lower ranks are stronger. These are descriptive discovery measures, not forecasts or investment recommendations.
The matched Census ZCTA reports a $1,839 median gross rent in the ACS 2024 five-year survey, making the current asking-rent index 9.68% higher. This is not a direct rent-growth comparison: ACS covers occupied renter homes, reports a median, and includes selected utilities, whereas ZORI tracks typical observed asking rents. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP, even though this ZCTA is the match for the Zillow ZIP market identifier. ACS median household income was $113,762. Applying a 30% share of income to the ZIP asking-rent index produces $80,680 of required annual income and an asking-rent-to-income arithmetic screen of 21.28%. That calculation is arithmetic only, not advice or an applicant qualification rule.
Bedroom figures are modelled estimates created by scaling ZIP ZORI with the local HUD bedroom ladder; they are never measured bedroom rents. The resulting monthly estimates are $1,673 for a studio, $1,731 for one bedroom, $2,017 for two bedrooms, $2,639 for three bedrooms, and $3,103 for four bedrooms. HUD’s local two-bedroom standard is $2,501, placing the ZIP’s all-rental-type ZORI at 80.65% of that standard. HUD FMR or SAFMR is an administrative, bedroom-specific standard rather than asking rent, so neither the HUD value nor the modelled ladder establishes what an available unit of a given size actually asks.
The ACS housing profile adds a separate tenant-side tension. Of 20,459 housing units in the matched ZCTA, 13,904 were single-family units and 3,787 were in larger multifamily structures, showing a mixed stock rather than a single rental format. The vacancy rate was 6.27%, with 711 units classified as vacant for rent; neither measure proves that a particular unit is vacant, available, appropriately priced, or comparable to the ZORI basket. Renters occupied 42.90% of occupied homes. Among renter households represented by ACS, 51.15% paid 30% or more of income toward gross rent. That burden measure describes surveyed occupied renter households, includes utilities through gross rent, and cannot be assigned to a prospective tenant or a specific property.
For broader context only, the Seattle city context asking-rent index was $2,224, the King County context asking-rent index was $2,330, and the Seattle-Tacoma-Bellevue, WA metro context asking-rent index was $2,269. Each wider-scope figure exceeds the ZIP’s ZORI, but these are context values rather than substitutes for ZIP-level evidence. The comparison identifies 98118 as lower in this asking-rent index than the named city, county, and metro contexts; it does not establish a reason, a neighborhood condition, or the rent for any building. The ZIP’s higher ACS burden share also should not be reconciled mechanically with these broader asking-rent benchmarks because the underlying universes differ.
The direct rolling-three-month Redfin ZIP resale observation is a distinct for-sale record, not rental transaction evidence. Median sold price was $819,315, up 8.09% year over year; 150 homes sold with a median seven days on market. Inventory was 111 homes and months of supply were 2.2. Sale-to-list signals were also elevated: the average sale-to-list ratio was 101.62%, 32.91% of sales closed above list, and 67.25% went off market within a fortnight. Annualized ZIP ZORI divided by median sold price equals 2.95%, but that is only a cross-source screening ratio, not a cap rate, net return, expected return, or property yield. The quick resale turnover challenges any simplistic reading that the lower ZIP asking-rent index alone defines market accessibility, while it cannot resolve the renter-burden evidence.
Important limits remain. ZORI blends rental types and reflects advertised asking conditions; ACS is a multi-year survey of occupied homes; HUD is an administrative standard; and Redfin describes ZIP resale activity. None measures a particular unit’s effective rent, lease concessions, utility treatment, condition, availability date, or tenant income. A property-level review would need the actual advertised rent by bedroom count, lease term and concessions, included utilities, unit size and condition, current listing status, comparable recently marketed rentals, and sale record details if resale evidence is relevant. The evidence supports careful comparison of these separate screens, not a forecast, a recommendation, or a conclusion about an individual household’s outcome.
