Resale pricing is the sharper current adjustment in 78230. Zillow’s ZIP ZORI, a typical observed asking-rent index blended across rental types, stands at $1,094 after a 3.1% year-over-year decline. The direct ZIP rolling-three-month Redfin resale observation reports a $362,807 median sold price, down 14.8% from a year earlier. Annualized ZIP ZORI divided by that sold-price median is 3.6%, but this is only a cross-source screening ratio, not a cap rate, net return, expected return, property yield, or measure of any individual home. The larger resale-price decline challenges a simplistic reading that a modest rent reduction alone describes current market adjustment.
The rent history supports a cooling classification, but its time horizons matter. Exact same-month annualized ZORI change was -3.1% over one year and -3.0% over three years, while the five-year change remained positive at 0.7%. Thus, the latest one-year decline confirms the more recent three-year path but breaks from the longer five-year growth record. The backward-looking series contains 114 monthly observations with 100% coverage. Annualized monthly-return variability of 3.2% means the path was not perfectly smooth, while the historical peak-to-trough drawdown reached 11.0%, demonstrating that a current asking-rent snapshot has limited stand-alone certainty. Transparent national discovery ranks among history-eligible ZIPs were 2,878 for momentum, 1,940 for stability, and 2,785 for the balanced measure; these are descriptive ranks, not forecasts or investment recommendations.
The rent sources answer different questions and should not be substituted for one another. The matched Census ZCTA’s ACS five-year survey reports median gross rent of $1,363 for occupied renter homes; gross rent includes selected utilities and is not a current asking-rent measure. HUD’s two-bedroom FMR/SAFMR standard is $1,530, an administrative bedroom-specific standard rather than asking rent. Scaling ZIP ZORI by the local HUD bedroom ladder produces modelled estimates of $829 for studios, $901 for one bedrooms, $1,094 for two bedrooms, $1,401 for three bedrooms, and $1,637 for four bedrooms. These are modelled estimates, not measured bedroom rents, and their purpose is to preserve the ZIP asking-rent level while reflecting the local HUD bedroom relationship.
The required-income screen is mechanical rather than a qualification outcome. At a 30% rent-to-income threshold, the current ZIP asking-rent index translates to required annual income of $43,760, compared with a ZCTA median household income of $73,529. That arithmetic does not advise on affordability, determine whether an applicant qualifies, or account for taxes, debt, household size, utilities beyond the index definition, or a specific lease. Separately, the ACS renter-household burden measure identifies 4,880 of 9,767 renter households as paying at least 30% of income toward rent, or 50.0%. This survey-based burden result signals broad household exposure, but it cannot establish the burden, lease terms, or payment capacity associated with a particular unit.
Housing composition provides another reason not to treat the asking-rent index as a single-property quote. The ZCTA has 21,269 housing units, of which 2,135 are vacant, producing a 10.0% vacancy rate. Of vacant units, 1,146 are classified as for rent. Renters account for 51.0% of occupied homes, so the area’s occupied stock is slightly renter-majority. The reported structure mix includes 10,979 single-family units and 3,295 units in large multifamily structures, showing that the population of homes underlying renter and rent statistics is varied. Vacancy and for-rent counts describe the area’s stock at survey scope; they neither prove availability of a specific residence nor indicate its condition, pricing, concession terms, or likely time on market.
Wider geography supplies context, not replacement evidence for the ZIP. For wider context only, the City of San Antonio rent measure is $1,382, the Bexar County rent measure is $1,389, and the San Antonio-New Braunfels, TX metro rent measure is $1,416. The ZIP’s current asking-rent index sits below each broader-area value, but those values do not function as ZIP rental comparables because their geographic scopes differ. The City of San Antonio context has a 53.7% renter burden share, above the ZIP’s survey burden share, while the county and metro figures remain contextual rather than property-level evidence. The ZIP’s lower asking level and its recent rent decline should therefore be read alongside, not replaced by, wider-area benchmarks.
Liquidity evidence in the for-sale universe is measurable but should remain separate from rental evidence. Redfin recorded 95 homes sold in the direct ZIP rolling-three-month resale window, with a median 40 days on market. Inventory was 151 homes and months of supply stood at 4.8. Sellers received an average 97.2% of list price, and 14.1% of sales closed above list. These are resale-market signals, not rental transactions, leasing comparables, or property operating economics. Together with the decline in median sold price, the marketing and sale-to-list measures suggest a resale setting that is less supportive of automatic pricing assumptions than the ZIP’s current rent snapshot might imply. That tension is especially relevant because both rent history and resale pricing are moving downward, though at materially different observed rates.
The 78230 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. The evidence also has distinct timing and construction: ZORI observes typical asking rents, ACS summarizes surveyed occupied renter homes, HUD sets administrative standards, and Redfin records completed resale-market activity. Before applying these area-level signals to a property, verify the actual advertised rent, bedroom count, included utilities, concessions, lease duration, unit condition, and availability date. For a resale comparison, verify recent closed sales, property type, living area, lot characteristics, renovation status, listing history, and whether the relevant transaction falls inside the ZIP rather than merely using a nearby mailing address.
