At the June 2026 endpoint, ZIP 95136’s Zillow Observed Rent Index (ZORI) is $3,475 per month. ZORI is a typical observed asking-rent index blended across rental types, not a quote for a specific lease. As wider context only, San Jose city’s rent is $3,478.67, Santa Clara County’s rent is $3,732, and the San Jose–Sunnyvale–Santa Clara, CA metro’s rent is $3,729. The near-city match should not be treated as an identical unit mix or as evidence that any available home carries that price. It does establish the principal evidence tension: ZIP asking rents are rising in the recent history, while the direct ZIP resale observations discussed below show lower prices and more inventory. A market index cannot determine a particular home’s rent when bedroom count, lease timing, condition, and included utilities differ.
Recent rent direction is faster than the preceding multiyear path. Through the stated June endpoint, exact same-month ZIP ZORI growth was 6.29% over one year, versus annualized 3.09% over three years and 4.39% over five years. The accelerating history label is descriptive: the latest rate confirms the longer positive path and is faster than both lookbacks. These are backward-looking measurements, not forecasts. Coverage is complete, with 102 monthly observations producing 101 consecutive monthly returns and leaving no documented gap in the supplied interval. The annualized monthly-return variability is 2.62%, so the current index deserves measured rather than absolute confidence: the history shows month-to-month movement even with no supplied coverage gaps. The maximum drawdown reached 5.11% at one point, separately showing that the path included declines. Among history-eligible ZIPs nationally, transparent discovery ranks were 506 for momentum, 916 for stability, and 280 for the balanced measure; lower is stronger, but the ranks are neither predictions nor investment recommendations.
That ZORI is not interchangeable with the matched Census source. The ACS 2024 five-year survey for the ZCTA reports a $2,762 median gross rent among occupied renter homes; gross rent includes selected utilities. The current asking-rent index is 25.81% higher. This gap need not be rent growth for one apartment, because ZORI measures a typical observed asking-rent index and ACS surveys occupied renters over a five-year period. The five-digit label is both the Zillow ZIP market identifier and the Census ZCTA match. A ZCTA is a statistical area, not an identical geography to a USPS delivery ZIP. Together, these sources frame distinct market concepts, not interchangeable rent comparables.
Bedroom detail is also modelled rather than measured. Scaling ZIP ZORI using the local HUD bedroom ladder produces modelled monthly estimates of $2,619 for a studio, $2,980 for one bedroom, $3,475 for two bedrooms, $4,589 for three bedrooms, and $5,001 for four bedrooms. The FY 2026 HUD two-bedroom FMR/SAFMR standard is $3,370. HUD FMR/SAFMR is an administrative, bedroom-specific standard, not asking rent; its purpose and scope differ from Zillow’s observed asking-rent index. Accordingly, the scaled bedroom figures organize a size-sensitive comparison but cannot establish an actual quote, included services, eligibility result, or observed bedroom rent for a particular home. The two-bedroom modelled value aligns with ZIP ZORI by construction, not through a separate measurement.
The affordability calculation offers a similarly limited screen. Applying a 30% rent-to-income rule to annualized ZIP ZORI produces required income of $139,000. It is arithmetic, not advice and not an applicant qualification rule. The ZCTA’s median household income is $142,433, making annualized ZORI 29.28% of that broad household-income statistic. That near-threshold relationship should be read alongside the ACS burden result: 3,359 of 6,696 renter households, or 50.16%, reported spending at least the screen threshold on gross rent. Surveyed gross-rent burden includes the ACS gross-rent definition and reflects occupied renters, not today’s applicants. It cannot prove whether any individual renter, lease, or property is affordable or burdened.
Stock and vacancy counts add context without showing live rental availability. The ZCTA has 16,730 housing units, of which 424 are vacant, for a 2.53% overall vacancy rate; 248 vacancies are classified for rent. Renters account for 41.06% of occupied units. The structure inventory includes single-family units and units in large multifamily structures, but its counts do not identify their tenure, asking price, or present market status. The rate is below the wider-context rates for San Jose city and Santa Clara County. These Census counts support a low unoccupied-unit share in the ZCTA but do not reveal turnover, concessions, condition, or whether any vacant unit is relevant to a particular renter.
Resale evidence belongs to a separate direct rolling-three-month ZIP for-sale universe. At the June 2026 resale endpoint, the median sold price was $1,299,706, down 1.91% year over year. There were 85 homes sold and median marketing time was 19 days. Inventory was 56 homes, 16.47% above its year-earlier reading, alongside 2 months of supply. The average sale-to-list ratio was 102.68%, while 49.44% of sales closed above list. These are resale liquidity and pricing signals, not rental transactions, rent comparables, or property economics. Annualized ZIP ZORI divided by median sold price equals 3.21%, solely a cross-source screening ratio, not a cap rate, net return, expected return, or property yield. The lower median price and higher inventory challenge a simple extension of accelerating rent history into resale; short marketing time and above-list outcomes keep the resale snapshot from reading as uniformly weak.
Timing, boundary, and unit definition limit every conclusion. ZORI is a ZIP-level asking-rent index at its stated endpoint; ACS is a five-year ZCTA survey with sampling uncertainty; HUD is a fiscal-year administrative standard; and Redfin is a rolling-three-month ZIP resale observation. City, county, and metro figures are wider context only, rather than replacements for a ZIP measure. A property-level review should confirm that the address belongs to the relevant ZIP and Census match, the actual bedroom count, current advertised rent, included utilities, lease term, and quote date. Separately verify sale records, active competition, and whether any sale comparison matches the property’s physical characteristics and transaction timing. Those checks retain the demonstrated contrast among index, survey, standard, and resale evidence instead of translating aggregate data into a claim about a particular home. Which source definition and property facts would change the conclusion most?
