At $1,299 in June 2026, Zillow’s ZIP-level ZORI frames 85719 as a current typical observed asking-rent index blended across rental types. It is not a signed-lease series, an individual listing quote, or a statement about a particular home. The five-digit label is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. That distinction matters before comparing the index with survey households, HUD standards, or home sales. By itself, the figure provides market-level scale, but its blended composition leaves property-specific rent, utilities, bedroom count, and concessions unobserved.
Rent history supplies a backward-looking test of whether today’s asking index is an isolated level. The direct Zillow ZIP series through its stated endpoint has 100% coverage. Exact same-month annualized changes are 1.00% over 1 year, 1.05% over 3 years, and 4.43% over 5 years. Thus, recent direction confirms continued upward movement but breaks from the materially faster longer path. Monthly returns produce 2.82% annualized variability. That contained historical movement supports moderate, not absolute, confidence that one current index value is not merely an outlier; it does not signal an assured next step. Separately, the deepest peak-to-trough retreat reached 2.39%, setting a historical loss boundary for the index. Transparent national discovery ranks, where lower ranks are higher, are 1,985 for momentum, 1,276 for stability, and 1,901 for balanced performance among history-eligible ZIPs. Those ranks and measurements describe past observations, not forecasts or investment recommendations.
The ACS creates a separate affordability and occupancy lens. In the matched Census ZCTA’s ACS 2024 5-year survey of occupied renter homes, median gross rent was $1,146, including selected utilities; that survey median is 13.4% below the Zillow asking-rent index. Its median household income was $42,241. Applying the stated 30% screen to annualized ZIP ZORI produces $51,960 of required annual income. This is arithmetic for comparison, not advice and not an applicant-qualification rule. The survey also records 9,061 renter households with gross-rent burden at or above that screen, a 61.0% share. The burden result describes respondents and their reported housing costs across the ZCTA, so it cannot establish that a specific available unit is affordable, occupied, or burdened.
Bedroom detail comes from a third universe, not from observed ZIP bedroom quotes. The local FY2026 HUD FMR/SAFMR ladder is a bedroom-specific administrative standard rather than asking rent. Scaling ZIP ZORI by that local ladder, anchored to the HUD two-bedroom standard of $1,380, yields modelled monthly ZIP estimates of $894 for a studio, $998 for one bedroom, $1,299 for two bedrooms, $1,807 for three bedrooms, and $2,080 for four bedrooms. These are modelled estimates, never measured bedroom rents. The two-bedroom result equals the ZIP index by construction, while the other amounts express the HUD bedroom relationships; they do not verify a unit’s size, amenities, utility treatment, or quoted rent.
Survey stock explains why neither the index nor a vacancy percentage should be read as an available-unit count. The matched ZCTA has 22,463 housing units: 20,609 are occupied and 1,854 vacant, yielding an 8.3% vacancy rate. Renter-occupied homes account for 72.1% of occupied units, emphasizing that survey rental households are a large component of the area’s housing base. Its recorded structure mix includes 11,089 single-family units and 5,314 units in the large-multifamily category. These are broad ACS stock measures collected over the survey period. They do not identify current listing supply, physical condition, turnover, or whether any particular address is vacant, rent-ready, or suitable for a particular household.
Broader places give scale but not substitutes for ZIP evidence. For wider-geography context only, the City of Tucson context reports a $1,424.65 rent index, while the Pima County context and Tucson, AZ metro context each report $1,483; all are above the direct ZIP index. Their scope is expressly citywide, countywide, and metropolitan rather than the matched ZIP/ZCTA area. The gap therefore identifies a contextual difference in the reported rent measures, not a comp set, a neighborhood conclusion, or a reason to assume any specific dwelling will follow the wider pattern. The ZIP’s renter-heavy survey composition further counsels against treating broader averages as interchangeable with its observed asking-rent index.
Resale evidence introduces a separate tension. Redfin’s direct rolling-three-month ZIP resale observation concerns the for-sale market, not rental transactions. Median sold price was $365,417, down 3.84% from a year earlier. It recorded 109 homes sold, a median 55 days on market, inventory of 133 homes, and 3.7 months of supply—direct measures of resale activity and marketing conditions. The average sale-to-list relationship was 97.69%, while 17.94% of sales closed above list; both remain resale signals only. Dividing annualized ZIP ZORI by the median sold price produces a 4.27% cross-source screening ratio, not a measure of property income, expenses, financing, or expected outcome. The contrast between still-positive ZIP rent history and a lower resale price challenges any simple reading of the rent series or ratio as uniform market strength; it also does not resolve the ACS household-income screen.
Decision limits are consequential here. ZORI is a blended asking-rent index, ACS is a multi-year survey of occupied households, HUD is an administrative standard, and Redfin is a short resale observation; matching their numbers does not turn them into one property-level dataset. Historical changes remain backward-looking measurements rather than forecasts. A property-level review would need the actual advertised rent, bedroom count, utility allocation, lease length, concessions, availability date, and building form. For a contemplated sale, it would separately require the recorded closing price, list history, condition, occupancy status, association charges where applicable, and the responsibility for taxes, insurance, and repairs. Does the exact dwelling’s verifiable rent, terms, and sale facts align with the relevant source universe, rather than relying on whether a broad index, burden share, or resale screen appears favorable?
