Current Zillow ZORI for ZIP 85339 is $2,133, down 0.28% from the same month a year earlier. This is a typical observed asking-rent index blended across rental types, rather than a lease-level rent quote or a measure of every available unit. The five-digit label is both a Zillow ZIP market identifier and a Census ZCTA match. For wider rental context, Phoenix city has a $1,569 rent measure, Maricopa County has a $1,729 rent measure, and the Phoenix-Mesa-Chandler, AZ metro has a $1,733 rent measure; each is a broader geographic context rather than a ZIP substitute. The immediate tension is that this ZIP’s asking-rent index remains above each comparator while its latest direction is slightly negative.
The cooling label is supported by the backward-looking Zillow history, not by a forecast. Exact same-month annualized ZORI change was negative 0.28% over one year, but positive 0.77% over three years and positive 3.55% over five years. Thus, the latest decline breaks from the longer upward path rather than confirming it. The history has full coverage. Monthly changes produced 2.66% annualized variability, which means a single current index reading deserves more caution than a perfectly steady series would. Its maximum peak-to-trough drawdown was 1.21%, a comparatively limited historical setback. Transparent national discovery ranks among history-eligible ZIPs were 2,389 for momentum, 996 for stability, and 2,048 for the balanced measure, where lower ranks are higher. Those ranks describe past measurements only.
The ACS comparison belongs to a different evidence universe. In the matched Census ZCTA, the ACS 2024 five-year median gross rent was $2,120 with a $148 margin of error; it covers occupied renter homes and includes selected utilities, rather than current asking rents. Zillow’s $2,133 asking-rent index is only 0.61% above that survey median, an unusually close cross-source reading that still does not make the measures interchangeable. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The same ACS source reports median household income of $110,602. Applying the structural 30% screen arithmetically to the current asking-rent index produces required annual income of $85,320, or 23.1% of reported median household income. This is not advice and is not an applicant qualification rule.
Bedroom figures are modelled estimates, not measured bedroom rents. Scaling ZIP ZORI through the local HUD bedroom ladder produces monthly estimates of $1,692 for a studio, $1,833 for one bedroom, $2,133 for two bedrooms, $2,847 for three bedrooms, and $3,155 for four bedrooms. HUD FMR or SAFMR is an administrative, bedroom-specific standard rather than asking rent; the local two-bedroom HUD standard is $2,420. The modelled two-bedroom estimate is therefore 88.1% of that HUD standard. This ladder is useful for keeping bedroom sizing internally consistent with the ZIP index, but it cannot identify a property’s advertised rent, utility treatment, condition, availability, or lease terms.
The ZCTA housing profile is owner-heavy and predominantly single-family, which limits how directly an aggregate blended rent index can be read as an apartment-market signal. Of 16,154 housing units, 433 were vacant, a 2.68% vacancy rate. Renters represented 18.0% of occupied homes, while 15,896 units were single-family structures. ACS counted 1,121 renter households spending at least 30% of income on gross rent, equal to 39.6% of renter households. That burden measure is a survey estimate for occupied renter homes, not proof that any specific available unit is affordable or unaffordable. Likewise, the aggregate vacancy count includes more than rentals and cannot establish whether a particular home is available, competitive, or priced at the ZIP index.
Direct ZIP resale evidence presents a related but separate cooling signal. In Redfin’s rolling-three-month for-sale observation, the median sold price was $459,886, down 2.15% year over year. There were 203 homes sold, median marketing time was 50 days, inventory was 254 homes, and months of supply stood at 3.8. The average sale-to-list ratio was 98.81%, while 21.34% of sales closed above list price. These are resale-market observations, not rental transactions or rental comparables. Annualized ZIP ZORI divided by the median sold price equals a 5.57% cross-source screening ratio only; it is not a cap rate, net return, expected return, or property yield. The resale price decline and below-list average reinforce the recent rent cooling direction, though the recorded sales activity prevents either source from being read as a no-activity market.
Read together, the evidence does not support treating one current rent number as a complete property conclusion. ZIP asking rent exceeds the named Phoenix city, Maricopa County, and metro context measures, yet it is nearly aligned with the ZCTA’s occupied-home gross-rent median. The longer rent history remains positive despite the latest decline, while the direct resale data also show softer annual pricing and marketing that is not uniformly fast. The low historical drawdown tempers the severity of the rent pullback, but the measured monthly variability argues against overconfidence in a single index snapshot. Cross-source agreement on broad level should therefore be separated from agreement on property type, bedroom count, utilities, tenant profile, or transaction timing.
The main limits are geographic matching, source definition, and aggregation. ZORI reflects observed asking rents across rental types; ACS reflects surveyed occupied renter homes; HUD supplies an administrative standard; and Redfin tracks completed ZIP resale activity. Property-level checks needed to test this aggregate screen include confirming that an address sits inside the relevant ZIP geography, matching bedroom count to the modelled ladder, reviewing current advertised rents and included utilities, checking active availability and lease terms, and comparing the specific home’s list and sale history with the resale observation. The useful closing question is not whether the ZIP index alone determines a unit’s rent, but whether those property facts remain consistent with the separate rent, affordability, stock, and resale measures reported here.
