At $1,318 in June 2026, ZIP 84116's Zillow Observed Rent Index records a typical observed asking-rent level blended across rental types, not the quote for a single home. The exact same-month one-year change is 4.67%, versus annualized exact same-month changes of 0.76% over three years and 4.35% over five years. Thus the recent rise breaks from the subdued middle-horizon path while more closely resembling the longer path; it is a backward-looking measurement, not a forecast. The history has 100% coverage, 3.68% annualized monthly-return variability, and a -3.81% maximum drawdown. This high-variability record calls for less confidence in any isolated current snapshot. Transparent national discovery ranks among history-eligible ZIPs are 1,187 for momentum, 2,405 for stability, and 1,927 for balanced results, with lower ranks higher.
Dollar proximity does not make the sources equivalent. The matched Census ZCTA's ACS 2024 five-year survey reports $1,338 median gross rent, with a supplied $54 margin of error, for occupied renter homes; it includes selected utilities and is a survey median rather than Zillow's blended asking-rent index. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP, so the geographic match is useful but not literal delivery-area identity. HUD's FY2026 two-bedroom FMR/SAFMR is $1,494. That HUD value is an administrative, bedroom-specific standard, not asking rent, and its function differs from both ZORI and ACS. Consequently, close-looking dollar figures across these universes should be read as differently constructed benchmarks, not confirmation that the same units transact or advertise at the same level.
Broader context makes the ZIP reading comparatively low, but it does not turn a context average into a local quote. Salt Lake City city-wide rent context is $1,629, Salt Lake County county-wide rent context is $1,639, and the Salt Lake City, UT metro-wide rent context is $1,638. All are above the direct ZIP ZORI. The city, county, and metro values are wider context only and should stay named at those scopes; they do not substitute for the ZIP-level asking-rent index or establish an advertised rent for a particular residence. The spread is decision-relevant because a reader comparing geographies could otherwise mistake a wider-area benchmark for this ZIP's rent level. It does not identify why the readings differ or imply a likely direction for either market.
Bedroom detail should not be inferred as if it were observed listing data. Scaling ZIP ZORI with the local HUD ladder produces modelled monthly estimates of $953 for a studio, $1,060 for one bedroom, $1,318 for two bedrooms, $1,764 for three bedrooms, and $2,094 for four bedrooms. These modelled estimates follow the local HUD bedroom relationship rather than a measured ZIP distribution of asking rents. The ladder is useful for keeping bedroom comparisons internally consistent, but it cannot establish the rent of an actual unit. HUD FMR/SAFMR remains an administrative bedroom-specific standard, not asking rent; therefore these outputs are modelled estimates, never measured bedroom rents or evidence of available inventory.
The income and burden evidence is more mixed than a single index-to-income ratio suggests. Annualizing the current index produces a $52,720 income screen at 30% of income. Against the ACS median household income of $66,751, the index is 23.7% of that median. This required-income screen is arithmetic, not advice, an affordability conclusion, or an applicant qualification rule. In the ACS renter-household universe, 3,617 of 6,919 households—52.3%—reported rent burdens at or above the screen's threshold. That survey result describes households and their gross-rent circumstances, not a particular building, lease, or prospective renter; it should not be used to infer a unit's cost, tenant profile, or payment outcome.
The physical-stock and vacancy picture requires the same separation of evidence. In the matched ZCTA, the vacancy rate is 7.59%, while the housing stock includes 8,008 single-family units and 4,013 units in large multifamily structures. These are aggregate stock classifications, not a count of comparable homes currently advertised for rent. A vacancy rate reflects the survey's vacant-unit universe and cannot by itself establish whether a specific property is rentable, competitively priced, occupied, in usable condition, or available on a target date. Nor does the mix of structure types identify amenities, lease terms, or quality. It provides scale and composition context, while the direct asking-rent index remains the distinct current rental measure.
The limits point to a property-level verification task rather than a mechanical conclusion. ZORI summarizes observed asking-rent conditions, ACS summarizes surveyed occupied renter homes, and HUD supplies an administrative standard; none is a listing record for a target home. The historical changes, volatility, drawdown, and discovery ranks describe the past only and are neither forecasts nor investment recommendations. For any specific listing, the relevant checks are the advertised base rent, bedroom count, lease term, included utilities, mandatory fees, concessions, actual availability, and condition. Those checks also determine whether the listing matches the bedroom model's assumptions. The operative question is whether the documented terms of that actual property align with the evidence universe being used, rather than whether one aggregate benchmark appears persuasive.
