The five-digit label 78212 is both Zillow’s ZIP market identifier and the match for a Census ZCTA. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. In June 2026, Zillow ZORI for 78212 was $1,565, down 0.2% from a year earlier. ZORI is a typical observed asking-rent index blended across rental types, rather than a measure of every signed lease. By contrast, the ACS 2024 five-year ZCTA median gross rent was $1,129 for occupied renter homes and includes selected utilities. The $62,600 income implied by the 30% screen nearly matches the ZCTA’s $62,801 median household income, but that screen is arithmetic only, not advice or an applicant qualification rule.
The recent rent direction breaks from, rather than confirms, the longer backward-looking Zillow history. The exact same-month one-year change was -0.2%, while the three-year annualized change was 0.5% and the five-year annualized change was 3.2%. Coverage was 100% across the available monthly history. Monthly-return variability annualizes to 2.9%, which means one current ZORI reading warrants more caution than a perfectly steady series would. Separately, the maximum drawdown was 2.8%, documenting a contained historical retreat from a prior peak. Transparent national discovery ranks among history-eligible ZIPs were 2,410 for momentum, 1,461 for stability, and 2,362 for the balanced measure; lower ranks are higher. These are descriptive backward-looking measurements, not forecasts, investment ratings, or recommendations.
The bedroom ladder should be read as a modelling device, not as a set of measured ZIP bedroom rents. Scaling ZIP ZORI using the local HUD ladder produces modelled monthly estimates of $1,185 for a studio, $1,297 for one bedroom, $1,565 for two bedrooms, $2,012 for three bedrooms, and $2,336 for four bedrooms. HUD FMR or SAFMR is an administrative, bedroom-specific standard rather than asking rent, and the local HUD ladder supplies the relative bedroom pattern used in this calculation. The estimated two-bedroom figure matching current ZORI does not establish that an observed two-bedroom unit rents at that level; unit condition, utilities, lease terms, and availability remain unobserved here.
ACS ZCTA housing data show 13,534 housing units, with 11,414 occupied and 2,120 vacant, for a 15.7% vacancy rate. Renters occupied 53.4% of occupied homes, so rental households form a slightly larger share of occupied homes than owners. The housing stock contains more single-family units than large multifamily units, a mix that should not be translated into a claim about any individual listing. Among 6,093 renter households, 2,812, or 46.2%, were rent burdened at the ACS threshold of spending at least 30% of income on gross rent. There were 809 units reported vacant for rent, but this category is not proof that a specific unit is currently available, suitably priced, or comparable with ZORI.
Wider geographies provide context only: the City of San Antonio city-scope rent measure was $1,382, Bexar County’s county-scope rent measure was $1,389, and the San Antonio-New Braunfels, TX metro-scope rent measure was $1,416, each below 78212’s current ZORI. The ZIP’s 29.9% asking-rent-to-income screen also exceeds the metro context’s 22.3% measure. Those comparisons sharpen the local affordability tension, but they do not replace ZIP evidence or establish why the differences exist. City, county, and metro figures each represent wider areas with different housing compositions, income distributions, and source scopes than the matched ZCTA and Zillow ZIP series.
The direct rolling-three-month Redfin ZIP resale observation belongs wholly to the for-sale market, not to rental transactions. It reports a $412,407 median sold price, up 0.1% year over year, with 68 homes sold and a median 75 days on market. The same ZIP resale view showed 257 active listings, inventory of 160 homes, and 7.2 months of supply. Average sale-to-list was 95.1%, while 7.6% of sales closed above list. These resale liquidity signals sit uneasily beside the ZIP’s higher asking-rent snapshot and positive longer rent history: prices were nearly flat, supply was substantial, and sales generally closed below list. Annualized ZORI divided by median sold price is a 4.6% cross-source screening ratio only; it is not a cap rate, property yield, net return, or expected return.
The sources answer different questions and should not be collapsed into one rent conclusion. Zillow ZORI is a blended asking-rent index; ACS gross rent is a survey measure of occupied renter homes with selected utilities; and HUD standards are administrative benchmarks. The ACS ZCTA also carries survey uncertainty, while ZORI does not identify a property’s utilities, concessions, lease duration, bedroom count, or physical condition. Likewise, Redfin’s resale figures measure completed ZIP home sales and listing conditions, not rental demand, rental turnover, or property operating costs. The cooling history and resale evidence can improve context around a rent snapshot, but neither establishes a future path or a unit-specific outcome.
A property-level review should verify the live asking rent, exact bedroom configuration, included utilities, concessions, lease term, deposit requirements, and whether the unit is genuinely available. It should also compare the property’s condition and location within the ZIP against recent competing listings, then separately review appropriate sale records if the for-sale market matters. Confirm whether a listing’s advertised rent aligns with the ZORI rental-type blend rather than assuming the index is a direct comparable. The unresolved question is whether a specific unit’s all-in monthly housing cost and competitive position support the ZIP-level screen once its own facts are known.
