For an evaluator of 98012, the distinctive decision question is whether a current ZIP-wide asking-rent benchmark is compatible with the target unit’s bedroom configuration and the household’s own finances, while recognizing that none of the aggregate series prices a specific property. The June 2026 Zillow Observed Rent Index (ZORI) is $2,640 per month, up 1.45% from a year earlier. ZORI is a typical observed asking-rent index blended across rental types, making it a current market signal rather than a promise for an available home. The ZIP label matches a Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. That geographic distinction matters whenever survey results below are read beside the Zillow ZIP market identifier.
The matched ACS 2024 5-year ZCTA offers income and renter-household evidence, not a readout of current listings. Median household income was $146,144, and renter-occupied households represented 33.6% of occupied homes. Within the ACS occupied-renter universe, 45.2% reported gross rent consuming 30% or more of income; that is an observed household burden measure, not evidence about any vacant or particular unit. Applying that share mechanically to the ZIP ZORI produces $105,600 in annual income. The corresponding annual ZORI-to-median-household-income comparison is 21.7%. Both calculations are aggregate screens: the required-income figure is arithmetic, not advice and not an applicant qualification rule, while the income ratio does not describe any individual household’s payment.
These rent series should remain separate, even when the dollar gap is useful. The ACS median gross rent is $2,373; it is a five-year survey measure for occupied renter homes and includes selected utilities. The current ZORI sits 11.3% above it, but the contrast mixes a current asking-rent index with a multi-year survey statistic, different housing universes, and potentially different utility treatment; it is not a time-series comparison. FY2026 HUD Fair Market Rent or Small Area Fair Market Rent is likewise distinct: its two-bedroom standard is $2,501, and ZORI is 5.6% higher. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent, so it must not be treated as confirmation of a listing’s market price or an ACS result.
Bedroom planning requires a different, explicitly modelled view. The local HUD ladder runs from $2,074 for a studio to $3,847 for a four-bedroom home, with two bedrooms as the scale anchor. Scaling the ZIP ZORI by the local HUD ladder yields modelled monthly ZIP estimates in studio-through-four-bedroom order: $2,189, $2,265, $2,640, $3,454, and $4,061, respectively. These are modelled estimates, never measured bedroom rents: the ZIP index is allocated across bedroom counts using the HUD ladder rather than observed bedroom-specific listings. The two-bedroom estimate equals the ZIP index because it is the scaling anchor. The widening upper-bedroom figures reflect the administrative ladder’s relative steps, not proof that every larger property asks those amounts.
Stock and vacancy describe the survey’s housing-unit composition rather than immediate rental supply. Single-family units account for 68.7% of the ZCTA housing stock, while units in large multifamily structures account for 12.9%. The ZCTA reports 771 vacant units, a 2.7% vacancy rate. Of those vacancies, 274 were designated for rent, 114 for sale, and 41 seasonal. These categories do not state condition, asking price, lease readiness, or bedroom count. In particular, a vacant-for-rent count is not evidence that any individual unit is available or that its rent aligns with ZORI, ACS gross rent, HUD standards, or the modelled bedroom estimates.
At the city scope, Bothell’s context rent is $2,685; at the county scope, Snohomish County’s context rent is $2,232; and at the metro scope, Seattle–Tacoma–Bellevue, WA’s context rent is $2,269. Thus the ZIP index is close to the city-scope figure and above the county- and metro-scope figures, but each is wider context only, not a substitute for the ZIP market identifier. Their geographies, housing mixes, and underlying observation universes may differ. The metro scope separately reports apartment vacancy, which is a property-subset indicator and should not be equated with the ZCTA’s all-housing-unit vacancy measure. Context helps frame scale; it does not establish a unit-level price, supply condition, or outcome.
Limits are material. ZORI is an index rather than a listing, ACS estimates have survey timing and sampling uncertainty, HUD is an administrative standard, and the bedroom ladder is a scaling model. Before attaching any conclusion to a property, verify that its delivery location falls within the relevant ZIP market identifier, its advertised bedroom count and monthly asking rent, whether quoted rent includes utilities or other recurring charges, lease term and availability date, and any deposits, concessions, or occupancy terms shown in the listing. Compare those facts separately with the appropriate benchmark: current all-type ZORI, the modelled bedroom estimate, ACS occupied-renter gross rent, or HUD standard. The burden and vacancy statistics describe groups and categories, not a specific home or a household’s approval, affordability, or experience.
