ZIP 59801’s strongest tension is between a current asking-rent signal and an occupied-home survey benchmark. Zillow’s June 2026 ZORI is $1,513 per month, up 5.0% from the same month a year earlier. ZORI is a ZIP-level typical observed asking-rent index blended across rental types; it is not a median lease for a fixed unit size. The matched Census ZCTA’s 2024 five-year ACS median gross rent is $1,124, and ZORI is 34.6% above that occupied-renter-home survey measure, which includes selected utilities. This source-universe difference is not evidence that a particular available unit is overpriced. The five-digit label is both the Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP.
The Zillow history is relatively complete but strictly backward-looking. It has 65 monthly observations and 100% coverage. Exact same-month annualized changes are 5.0% over one year, 3.9% over three years, and 5.3% over five years. Recent direction therefore confirms the longer positive path, but the one-year pace exceeds the three-year rate and trails the five-year rate; the direction aligns without duplicating its pace. Annualized monthly-return variability is 3.3%, and maximum drawdown is -1.7%. Those observed fluctuations make a single current snapshot more useful as an index point within a measured path than as a fixed unit quote. Transparent national discovery ranks among history-eligible ZIPs are 463 for momentum, 2,036 for stability, and 867 for balanced, where lower rank is higher. These are backward-looking measurements, not forecasts or investment recommendations.
Bedroom detail requires a model, not a claim of measurement. The FY2026 HUD FMR/SAFMR ladder is an administrative, bedroom-specific standard rather than asking rent. Scaling ZIP ZORI through this local HUD ladder produces modelled monthly estimates of $1,045 for a studio, $1,246 for one bedroom, $1,513 for two bedrooms, $1,974 for three bedrooms, and $2,353 for four bedrooms. The corresponding two-bedroom HUD standard is $1,508, which is the administrative benchmark used in the scaling relationship. The model retains the ZIP ZORI anchor at that bedroom size. These are modelled estimates, never measured bedroom rents, and neither HUD nor this model establishes the asking rent of an actual listing.
An arithmetic screen makes the pressure visible without becoming an eligibility judgment. At a 30% rent-to-income screen, current ZORI implies required annual household income of $60,520. That is above the ZCTA ACS median household income of $58,347, and the relationship is a 31.1% asking-rent-to-income ratio. This screen is arithmetic, not advice or an applicant qualification rule. Separately, ACS estimates that 4,388 of 8,626 renter households, or 50.9%, meet or exceed that gross-rent burden threshold. That burden result describes occupied renter homes, not a specific applicant or unit, and cannot prove payment pressure, lease terms, or utility responsibility at a particular property.
Stock evidence needs equally careful handling. The matched ZCTA has 16,053 housing units and an overall vacancy rate of 6.3%; renters account for 57.4% of occupied units. The structure mix contains more single-family units than large multifamily units, so the stock is not captured by one building form or bedroom mix. The 119 units counted vacant for rent are a survey category within the aggregate, not a live inventory or proof that a similarly priced unit is currently obtainable. Likewise, vacancy cannot establish condition, utilities, lease terms, or price for a given property.
The supplied wider-place comparisons set a different frame without replacing ZIP evidence. The ZIP’s current index is lower than the Missoula city context at about $1,550, the Missoula County context at $1,567, and the Missoula, MT metro context at $1,567. Each is context for a wider geography, not a substitute for the ZIP-level asking index or for a property quote. City, county, and metro values may help locate the ZIP within broader measures, but differences in geography, unit mix, and source scope prevent them from establishing a rent, vacancy outcome, or affordability result for an individual home.
Uncertainty and property-level fit are the final boundary. The ACS median gross-rent estimate’s 90% margin of error is $58, and the ACS median household-income estimate’s is $5,530. Those survey margins belong to ACS, not to ZORI or the HUD standard. Neither a blended asking index, an administrative bedroom standard, a burden statistic, nor a vacancy total identifies an actual unit’s condition or bill structure. Property-level checks include address-to-ZIP mapping, advertised rent, bedroom count, included and separately charged utilities, furnished status, availability date, lease length, concessions, and fees. Which current listings match the model’s bedroom, utility, and lease assumptions?
