At the June 2026 endpoint, the typical Zillow Observed Rent Index (ZORI) for ZIP 82901 is $1,061 a month, following a 4.48% exact same-month decline over 1 year. The clearest current tension is that the index still shows annualized same-month gains of 1.00% over 3 years and 4.70% over 5 years, while its latest direction breaks rather than confirms that longer upward path. This is a backward-looking measurement through the endpoint, not a forecast or investment recommendation. ZORI is a ZIP-level typical observed asking-rent index blended across rental types; it is neither a signed-lease average nor a set of bedroom-specific unit quotes. The decline describes recent index history and does not promise a next listing price or a renewal result.
That apparent reversal calls for more caution than a point estimate alone. The ZIP is classified as high variability: historical data coverage was 95.95%, annualized monthly-return variability was 4.13%, and the maximum drawdown was a 6.71% decline. The transparent national discovery ranks were 2,653 for momentum, 2,658 for stability, and 2,844 for the balanced measure among history-eligible ZIPs, with a lower rank higher. Those ranks are descriptive discovery tools rather than forecasts. Recent weakness, modest longer-period growth, volatility, and drawdown show a record that has not moved in a uniformly smooth line. This variability reduces the confidence a reader should place in one current rent snapshot as a description of every property, especially when rental types and lease terms differ.
Price comparisons require an explicit source boundary. This five-digit label is both the Zillow ZIP market identifier and the matched Census ZCTA geography. In ACS 2024 5-year data, the ZCTA median gross rent is $908, and the current ZORI level is 16.85% higher. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. ACS median gross rent is a five-year survey of occupied renter homes and includes selected utilities, whereas ZORI is a typical observed asking-rent index. The measures thus cover different universes, dates, and rent concepts. Their gap frames the distinction but cannot establish what an individual unit asks, includes in utilities, or leases for.
Bedroom sizing should likewise not be read as a set of observed listings. The modelled monthly ZIP estimates are $783 for a studio, $910 for a one-bedroom, $1,061 for a two-bedroom, $1,345 for a three-bedroom, and $1,780 for a four-bedroom. They are modelled estimates, never measured bedroom rents: each scales ZIP ZORI using the local FY2026 HUD bedroom ladder. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent. The modelled two-bedroom value is 6.53% above the supplied local HUD standard of $996. This ladder provides a consistent sizing framework, but it does not account for a home's condition, property type, utilities, furnishings, concessions, availability, or lease terms.
Affordability evidence adds a different lens, with its own limits. On a simple arithmetic screen, paying $1,061 monthly at 30% of gross income corresponds to $42,440 of annual income. This screen is arithmetic, not advice or an applicant qualification rule. In the ACS ZCTA universe, median household income is $69,954, producing an asking-rent-to-income calculation of 18.20%; it does not measure disposable income or an actual renter's rent share. Within the ACS occupied-renter universe, 1,232 of 3,053 renter households, or 40.35%, reported gross rent at or above 30% of household income. That survey-based burden result carries source uncertainty and cannot prove burden for a particular unit, household, or lease.
Stock counts describe scale, not a real-time availability list. In the matched ZCTA's ACS housing stock, 12,661 units include 1,078 vacant units, an 8.51% vacancy rate. Structure counts include 8,178 single-family units and 455 units in large multifamily structures. These vacancies and structure categories do not show whether a vacant home is habitable, marketed near the ZORI level, available on the needed date, or suitable for a given household. They also do not identify turnover timing, included utilities, concessions, or the number of options meeting a specific bedroom need. The stock evidence is therefore useful context, but not proof that any particular property is available or affordable.
For wider context only, the city-wide Rock Springs context rent is about $1,061, while the countywide Sweetwater County context rent and metro-wide Rock Springs, WY context rent are each $1,044; all apply to broader city, county, or metro scopes rather than the ZIP index or ZCTA survey. Scope matters before treating a close context figure as an address-level comparison. Concrete property-level checks need the actual delivery ZIP and relevant geography, advertised rent, availability date, bedroom count, included utilities, mandatory fees, deposit, concessions, furnishing status, lease term, and condition. The unresolved question is not whether an index is correct in the abstract, but which currently advertised property, under fully disclosed terms, is actually comparable.
