At June 2026, Zillow ZIP 85704 ZORI was $1,431, a typical observed asking-rent index blended across rental types. The exact same-month annualized changes were 1.05% over one year, 0.52% over three years, and 3.80% over five years. The positive latest direction confirms the longer path, but its pace exceeds the three-year figure and trails the five-year figure, so it does not reproduce either long-run speed. The supplied direct-Zillow history is classified high variability: it has 100% coverage, annualized monthly-return variability of 3.76%, and a maximum drawdown of -2.68%. Transparent national discovery ranks among history-eligible ZIPs are 2,084 for momentum, 2,456 for stability, and 2,593 for the balanced measure, with lower ranks higher. Those backward-looking measurements are not forecasts or investment recommendations; the variability means a current rent snapshot deserves less confidence than a steadier historical path would support.
The five-digit label is both Zillow’s ZIP market identifier and the matched Census ZCTA. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. In the ACS 2024 five-year survey, median gross rent was $1,561, with a $67 margin of error, for occupied renter homes and included selected utilities. That survey median was 8.3% above ZORI, but neither is a second quote for the same rental: ZORI represents typical observed asking rents, while ACS describes surveyed occupants. The FY2026 HUD two-bedroom FMR/SAFMR standard was $1,650. It is an administrative, bedroom-specific standard rather than asking rent, placing ZORI 13.3% below it. These source-universe differences preclude a like-for-like conclusion about any specific property.
Bedroom detail is created by scaling the ZIP ZORI with the local HUD ladder, rather than by separately observing listings. The resulting monthly modelled estimates are $989 for a studio, $1,101 for a one-bedroom, $1,431 for a two-bedroom, $1,986 for a three-bedroom, and $2,290 for a four-bedroom. The middle estimate matches the ZIP index by construction. These are modelled estimates, never measured bedroom rents: they preserve the HUD ladder’s relative bedroom structure but cannot show actual availability, utility treatment, property type, lease terms, or an advertised rent at any bedroom count. Their appropriate role is a consistent ZIP-wide comparison frame, not proof of what a particular unit should command.
At a 30% required-income screen, annualizing the current index produces $57,240 in annual income. That screen is arithmetic, not advice or an applicant qualification rule. The ACS ZCTA median household income was $81,696, with a $5,963 margin of error, and the asking-rent-to-income calculation was 21.0%. This compares a broad asking-rent index with a household-income median; it does not state what any renter pays. Separately, ACS reported 3,378 of 7,010 renter households as burdened at the source threshold, or 48.2%, with a $449 margin of error on the burdened count. That burden measure describes surveyed occupied renter households and cannot prove affordability, costs, or qualification for a particular unit.
Census ZCTA housing tables recorded 18,148 housing units, an overall vacancy rate of 8.2%, and a renter share of 42.1%. The structure tabulation contains more single-family units than large multifamily units, while the seasonal-vacancy category exceeds the vacant-for-rent category. Those patterns describe the area’s surveyed housing inventory and vacancy classifications, not the marketing status of a home. In particular, an all-housing vacancy rate does not show whether a vacant address is available now, offered for rent, suited to a renter’s bedroom need, or priced near the ZIP index. Vacancy and burden statistics remain area-level context rather than evidence about a specific listing.
As wider context only, Tucson city’s citywide context rent was $1,424.65, Pima County’s countywide context rent was $1,483, and the Tucson, AZ metro’s metro-wide context rent matched Pima County’s figure. The ZIP index falls between those wider values. Tucson city’s renter share was higher than the ZIP’s, whereas Pima County’s was lower; the ZIP vacancy rate sat between the city and county context rates. The metro apartment-vacancy measure covers apartments rather than the ZIP’s all-housing vacancy measure. These named city, county, and metro scopes provide comparison context only; they cannot redefine the ZIP market, reconcile the distinct source universes, or identify availability and lease terms at an individual listing.
Several limits remain material. ZORI is a blended ZIP asking-rent index, ACS is a multi-year ZCTA survey with margins of error, and HUD is an administrative bedroom standard; none is a live property quote. Useful property-level checks are the address and applicable market geography, quoted rent, bedroom count, property type, included utilities, lease term, recurring and nonrecurring fees, available date, and active listing status. Those checks determine whether comparison with the broad index or the modelled ladder is meaningful. The historical series remains descriptive through its endpoint, not a forecast. Which verified listing-specific facts support a valid comparison with these ZIP-wide measures?
