The central tension in ZIP 36606 is that the asking-rent series is rising while the for-sale series records a faster price gain and average closing below list. At June 2026, Zillow ZORI is $1,285 a month. ZORI is a ZIP-level, typical observed asking-rent index blended across rental types; it is not a census survey or a bedroom-specific quote. Mobile city context has $1,311.05, while Mobile County context and Mobile, AL metro context both stand at $1,335. Those named city, county, and metro figures are wider-area context, not ZIP observations. This ZIP label is both a Zillow ZIP-market identifier and a Census ZCTA match. A ZCTA is a statistical area, not identical to a USPS delivery ZIP, so these boundary labels should not be treated as interchangeable.
Through the June endpoint, the direct Zillow ZIP history consists of 69 monthly observations with 100% coverage. Exact same-month annualized ZORI changes are 4.61% over 1-year, 5.31% over 3-years, and 7.31% over 5-years. Annualized monthly-return variability is 3.02%, and the maximum drawdown is 1.35%. The transparent national discovery ranks among history-eligible ZIPs are 359 for momentum, 1,661 for stability, and 531 for the balanced measure; a lower rank is higher in each ordering. The current direction therefore confirms an upward rent path, but the smaller short-window gain breaks from the faster pace registered over the longer windows. The limited observed variability and drawdown support more confidence in this particular index snapshot than a highly erratic series, while neither supplies a forecast nor removes the need to inspect current listings. These are backward-looking measurements, not investment recommendations.
By contrast, ACS supplies a different housing universe. In the ACS 2024 five-year survey for occupied renter homes in the matched ZCTA, median gross rent is $980, which is 31.1% below the current ZORI. Gross rent includes selected utilities, while ZORI represents asking rents, so their spread should not be read as a newly signed-lease premium. The ZCTA median household income is $51,303. Annualizing the ZORI produces a $51,400 income figure under the 30% screen, placing the index almost exactly at that area-wide median-income benchmark. That screen is arithmetic only: it is not affordability advice, a household budget, or an applicant qualification rule. ACS is a survey, and its renter-home result cannot establish the rent or utility bill for any specific vacant or occupied unit.
Bedroom figures should be read even more narrowly. Zillow does not measure bedroom-specific ZIP asking rents in this packet. Instead, the ZIP ZORI is scaled with the local HUD ladder to create modelled monthly estimates of $1,008, $1,096, $1,285, $1,676, and $1,713 in ascending bedroom order from studio upward. They are modelled estimates, never measured bedroom rents. The ZORI-matching step is 26.0% above its corresponding HUD standard. The FY2026 HUD FMR/SAFMR is an administrative, bedroom-specific standard—either a ZIP SAFMR or county-derived ladder in this packet—not an asking-rent observation. Thus the ladder is useful for internally scaling the single ZORI index but cannot substitute for ads, leases, or rental comparables for a particular bedroom count.
The matched ZCTA had 9,148 housing units, including 985 vacant units, for a 10.8% overall vacancy rate. Its renter share was 51.3%, and the housing stock included 6,312 single-family units; those stock measures describe the ZCTA’s aggregate structure, not the supply or condition of any individual property. ACS reports no units classified as vacant-for-rent, but that survey estimate is not proof that no rental is available. It also cannot identify turnover, concessions, lease terms, or unit quality. Overall vacancy counts include multiple vacancy categories, so they cannot be repurposed as a rental-vacancy measurement. The evidence supports only a broad stock and occupancy reading.
Measured burden reinforces the tight arithmetic screen but remains a survey result, not a property attribute. ACS reports 2,121 of 4,190 renter households spending at least 30% of income on rent, a 50.6% burden share. Mobile city context has a higher renter-burden share, but that city comparison is wider context rather than ZIP evidence. The burden estimates describe households in the survey universe, and they do not prove that tenants in a given building are cost burdened, that a particular rent is affordable, or that a unit will lease. Income, utilities included in gross rent, household composition, and contract terms are not equivalent between an asking-rent index and a household survey.
Redfin’s direct rolling-three-month ZIP resale observation is a for-sale market measurement, never a rental transaction dataset. It reports a $189,957 median sold price, up 7.02% year over year, with 72 homes sold, 32 median days on market, and an inventory reading of 84 homes. The reported 3.5 months of supply expresses inventory against recent sales flow, not rental availability or a universal buyer–seller balance label. The average sale-to-list ratio was 96.6%, and 20.0% of sales closed above list. The resale price increase exceeds the ZORI increase, challenging a simple combined strength reading from rent history and resale pricing; it does not change the arithmetic income screen. It also does not link sale prices to the actual rents, expenses, or condition of individual properties.
Several limits prohibit turning the aggregate readings into property economics. Annualized ZIP ZORI divided by median sold price is a cross-source screening ratio only, not a measure of property-level economics or any form of return. Zillow’s blended index, ACS renter-home survey, HUD standard, and Redfin resale records do not form a matched set of transactions for an individual building. Concrete property-level checks would need to reconcile the current advertised rent and concessions by bedroom, lease length, utility responsibility, unit condition and availability, and nearby sale dates, list terms, and closing terms. They would also need to verify that the address is in the intended delivery ZIP and that its boundaries align with the ZCTA match. Which exact rent, utility, bedroom, and resale records actually describe the property under review?
