The clearest tension in 84102 is between a softening current asking-rent index and a rising direct resale price. In June 2026, Zillow’s ZIP-level ZORI is $1,516, down 0.82% year over year, while Redfin’s direct rolling-three-month ZIP resale observation reports a $634,357 median sold price, up 6.61% from a year earlier. The divergence does not map a sale price onto a lease: ZORI describes asking rents and Redfin records for-sale outcomes. It is nevertheless the central current screen. The rent measure has weakened even as the resale measure rose, so neither side can establish the other’s level, cause, or future direction.
The five-digit label is both Zillow’s 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. The matched ACS 2024 five-year survey instead reports $1,386 median gross rent for occupied renter homes and includes selected utilities. The Zillow index is 9.38% higher than this survey measure, which is informative context but not a like-for-like quote comparison. HUD’s FY2026 FMR/SAFMR ladder is a separate administrative, bedroom-specific standard, not asking rent. Keeping those definitions separate avoids treating one source as another.
To create an indicative bedroom sequence, the ZIP-wide ZORI is scaled by the local HUD ladder. The resulting modelled monthly ZIP estimates are $1,096 for a studio, $1,219 for one bedroom, $1,516 for two bedrooms, $2,029 for three bedrooms, and $2,409 for four bedrooms. These are modelled estimates, never measured bedroom rents, and the apparent alignment of the two-bedroom estimate with the ZIP index is a consequence of the scaling method. They provide a proportional screen across bedroom counts, not evidence on advertised rents, lease outcomes, utility treatment, or the actual mix of available units within each bedroom class.
The history supplies a separate caution. Exact same-month annualized ZORI changes were -0.82% over 1 year, -0.23% over 3 years, and +3.58% over 5 years. Recent direction therefore breaks from, rather than confirms, the positive longer path. Annualized monthly-return variability was 3.51%, and the maximum drawdown was -4.22%. Coverage was 100%, allowing the full observed path to be evaluated rather than a partial series. Transparent national discovery ranks among history-eligible ZIPs were 2,584 for momentum, 2,249 for stability, and 2,751 for the balanced measure, where a lower rank is higher. Classified as high variability, this backward-looking record lowers confidence that one current rent snapshot represents a settled level; it is not a forecast or an investment recommendation.
Affordability pressure is visible in an arithmetic cross-source screen, not in an applicant test. The ZCTA’s ACS median household income was $52,199. At the structural 30% threshold, the current monthly asking-rent figure corresponds to $60,640 of annual income and equals 34.9% of reported median income. Separately, ACS counted 4,710 of 7,894 renter households, or 59.7%, with gross-rent burden at or above that threshold. The required-income screen is arithmetic, not advice or an applicant qualification rule. Income, burden, and gross-rent findings are area-level survey evidence, so they cannot prove what a particular household can pay or what an individual unit costs.
Tenure and stock point to renter concentration and vacancy, but not to a unit-level availability claim. Renter-occupied homes made up 76.0% of occupied housing, overall housing vacancy was 9.75%, and 336 units were classified as vacant for rent. Large-multifamily stock exceeded single-family stock in the matched ZCTA. These are aggregated categories; vacant-for-rent status does not establish an available term or price for a particular unit. For wider geographic context only, Salt Lake City city-context rent was $1,629.21, Salt Lake County county-context rent was $1,639, and Salt Lake City, UT metro-context rent was $1,638. Each exceeds the ZIP index, but wider contexts are not property-level rental comparisons.
Redfin liquidity indicators must remain in the direct ZIP for-sale universe. Its rolling-three-month resale observation documented 62 homes sold, a median 42 days on market, inventory of 86 homes, and 4.2 months of supply. Sales averaged 98.8% of list price, while 20.02% sold above list. The resale price advance and these transaction signals contrast with the current rent decline and area-level affordability pressure, challenging a simple reading that rent-side conditions describe all housing activity. They do not document rental transactions. Annualized ZIP ZORI divided by the reported median sold price is 2.87%, a cross-source screening ratio only; it does not supply unit-specific expenses, rental terms, or transaction pairing.
Scope and timing differences impose firm limits. ZORI is a blended ZIP asking-rent index, ACS is a ZCTA survey, HUD is an administrative ladder, and Redfin is a resale observation; they are not synchronized listing comparables or a record of one property’s economics. A property-level review would need to verify the exact advertised asking rent, bedroom count, current availability, whether utilities are included, and the actual terms of any relevant sale. It would also need to distinguish an advertised listing from a completed transaction. Does the specific property actually match the rent definition, bedroom category, utility treatment, and availability that these area-level screens cannot observe?
