Cooling in the ZIP-level rent series is the central signal for 78216. In June 2026, Zillow ZORI was $1,132 per month, a same-month decline from a year earlier. ZORI is a typical observed asking-rent index blended across rental types; it is not a lease-level quote or a measure of every occupied home. The City of San Antonio context, Bexar County context, and San Antonio-New Braunfels, TX metro context each had a higher Zillow asking-rent benchmark, but those wider geographies are context rather than substitutes for the ZIP reading. The five-digit label is both a Zillow ZIP market identifier and a Census ZCTA match.
That current drop extends a longer cooling phase but reverses the full five-year path. Exact same-month ZORI changes were -7.6% over one year, -2.6% annualized over three years, and +1.2% annualized over five years. The recent direction therefore confirms the three-year decline while breaking from the longer positive trajectory, rather than establishing a forward view. Annualized month-to-month return variability was 3.2%, so a single current rent snapshot deserves measured confidence rather than a fixed-rent interpretation. The series' maximum drawdown was 8.4%, a separate record of the largest historical peak-to-trough retreat. History coverage was 100%. Among history-eligible ZIPs, transparent national discovery ranks were 2,898 for momentum, 1,933 for stability, and 2,795 for the balanced measure; lower ranks are higher. These are backward-looking measurements, not forecasts or investment recommendations.
Bedroom figures should not be read as observed unit rents. They are modelled monthly ZIP estimates that scale the ZIP ZORI through the local HUD ladder: $858 for a studio, $934 for one bedroom, $1,132 for two bedrooms, $1,451 for three bedrooms, and $1,694 for four bedrooms. The corresponding HUD standards are $1,130, $1,230, $1,490, $1,910, and $2,230. HUD FMR/SAFMR is an administrative, bedroom-specific standard, not asking rent; it can differ from the ZORI index by design. Thus the ladder helps make bedroom comparisons internally transparent, while it does not measure the rent of a particular available studio, apartment, or house.
The Census match requires a different lens. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The ACS 2024 five-year survey reports a $1,234 median gross rent among occupied renter homes and includes selected utilities, whereas ZORI reflects typical observed asking rents across rental types. Its higher historical survey median is therefore not a contradiction of the current index. For a simple 30% required-income screen, annualizing the current ZORI produces $45,280; the ZCTA median household income is $59,110. This is arithmetic only, not advice, an applicant qualification rule, or evidence about what any individual household can pay.
Burden data qualifies that arithmetic screen. In the ACS ZCTA survey, 7,228 of 12,608 renter-occupied households, or 57.3%, had rent burdens above the threshold. The City of San Antonio context and Bexar County context each had lower renter-burden shares; both are wider-area comparisons, not ZIP-level asking-rent measures. The ZIP's higher survey burden and lower current asking-rent index can coexist because they answer different questions, populations, periods, and rent definitions. Neither burden status nor a median-based income screen proves affordability, payment performance, or conditions for a particular unit.
Housing composition adds another constraint without identifying unit availability. The ZCTA contains 22,027 housing units and is renter-majority, with a 64.8% renter share. Its 11.7% vacancy rate includes 1,613 units classified vacant for rent, alongside other vacancy categories, while the stock spans single-family units and large multifamily units. These counts describe the ZCTA's survey housing inventory, not a contemporaneous list of rentable homes, and they do not establish the condition, price, concessions, lease terms, or vacancy of any specific property. They nonetheless set the local survey backdrop for interpreting the burden figures and blended asking-rent index.
The direct ZIP resale reading gives a parallel cooling signal, but it belongs entirely to the for-sale market. In Redfin's direct rolling-three-month ZIP resale observation, median sold price was $344,922, down 6.7% year over year; 73 homes sold and median marketing time was 45 days. Inventory was 146 homes, with 6.1 months of supply. The average sale-to-list ratio was 97.63%, and 18.33% of sales closed above list. Those are resale liquidity and pricing signals, not rental transactions or property economics. The annualized ZORI divided by median sold price is a 3.94% cross-source screening ratio only; it is not a cap rate, net return, expected return, or property yield.
The decision tension is that current and longer-horizon rent cooling, together with a softer resale price reading, point in the same backward-looking direction, while the ZCTA burden share remains elevated and the distinct data universes cannot be collapsed into a unit-level conclusion. Resale evidence therefore confirms the cooling direction in the history, but it does not validate the income screen or explain burden. For any address, unresolved checks include the actual advertised rent and bedroom count, included and separately billed utilities, lease duration and concessions, current availability, and whether relevant closed sales match the property's type, condition, timing, and location. Those facts require property-level confirmation because the ZIP index, ZCTA survey, HUD standard, and rolling resale observation have distinct limits.
