The most immediate tension in 95112 is between a current Zillow asking-rent snapshot of $3,131 and the income screen implied by that level. Zillow ZORI rose 4.3% from the same month a year earlier, yet annualizing that index and applying a 30% screen produces required household income of $125,240, above the matched area’s $89,103 median household income. The resulting 42.2% asking-rent-to-income comparison is arithmetic only: it is not advice, an applicant qualification rule, or evidence that any particular household cannot rent a particular home. Zillow ZORI is a typical observed asking-rent index blended across rental types, rather than a lease-level measure of every available unit.
Its history supports a stable-growth reading, but not a claim of uninterrupted gains. The one-year exact same-month rent-history change is 4.3%; the three-year annualized change is 3.7%; and the five-year annualized change is 4.4%. Recent direction therefore broadly confirms the longer path, with the one-year pace above the three-year pace but close to the five-year result. Annualized monthly-return variability is 2.4%, which supports moderate confidence in the current index as a snapshot rather than a precise unit quote. Separately, the 10.7% maximum drawdown shows that past declines have occurred. History coverage is 100% across 112 observations and 111 consecutive returns. Transparent national discovery ranks are 628 for momentum, 533 for stability, and 202 for the balanced measure; lower ranks are stronger, and all are backward-looking measurements rather than forecasts or investment recommendations.
The bedroom figures are modelled estimates, not measured bedroom rents. Scaling ZIP ZORI through the local HUD FMR/SAFMR ladder yields modelled monthly estimates of $2,353 for a studio, $2,681 for one bedroom, $3,131 for two bedrooms, $4,134 for three bedrooms, and $4,502 for four bedrooms. The HUD ladder itself lists administrative standards of $2,300, $2,620, $3,060, $4,040, and $4,400 for those bedroom sizes. HUD FMR/SAFMR is a bedroom-specific administrative standard, not asking rent, while the Zillow index is blended across rental types. The ladder is useful for preserving local bedroom spacing, but it cannot substitute for unit-level observations of size, condition, lease term, or included utilities.
The lower ACS rent figure is not a contradiction; it measures a different universe. The five-digit label 95112 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. In the matched ACS five-year survey of occupied renter homes, median gross rent is $2,186 with a $69 margin of error, and gross rent includes selected utilities. That figure is 43.2% below the Zillow asking-rent index, a gap consistent with comparing occupied-home survey responses with a current asking-rent index. The survey reports 15,876 renter-occupied homes, with 8,280 households, or 52.2%, spending at least 30% of income on rent. Burden is a household-survey measure and does not prove the affordability, rent, or utility terms of any specific vacant unit.
Housing composition and vacancy provide additional context without identifying conditions at a particular property. The ZCTA contains 23,628 housing units, including 8,337 units in large multifamily structures. Its vacancy rate is 8.7%, and renter households represent 73.6% of occupied homes. For broader context only, San Jose city context has a $3,479 rent index and a 44.2% renter share, Santa Clara County context has a $3,732 rent index and a 44.9% renter share, and the San Jose-Sunnyvale-Santa Clara, CA metro context has a $3,729 rent index. The ZIP’s lower asking-rent index than each wider geography sits beside a much higher renter share than the city and county context. Those wider values are comparison points, not substitutes for ZIP-level asking-rent, housing-stock, or vacancy evidence.
Redfin supplies a separate direct rolling-three-month ZIP resale observation, and its liquidity signals are firm but remain entirely in the for-sale universe. The median sold price is $1,114,748, up 6.9% year over year, with 64 homes sold and median marketing time of 17 days. Redfin reports 144 active listings, inventory of 59 homes, and 2.8 months of supply. The average sale-to-list ratio is 102.26%, while 46.8% of homes sold above list price and 39.5% went off market within two weeks. These are resale outcomes, not rental transactions, rental comparables, or evidence about the economics of a rental property. Faster resale activity and price appreciation challenge any attempt to infer the whole housing market from rent growth or renter-burden data alone.
Cross-source comparison produces a 3.37% screening ratio when annualized ZIP ZORI is divided by Redfin’s median sold price. This is only a mechanical screening ratio joining an asking-rent index to a resale median; it does not measure operating expenses, taxes, financing, maintenance, lease-up periods, concessions, or unit-specific pricing. The resale evidence confirms that the ZIP’s direct for-sale market had relatively limited supply and quick marketing, while the rent and income screens show that current asking rent is materially above the ACS occupied-renter median and high relative to the local household-income benchmark. Neither side resolves the other because their populations, timing, and transaction types differ.
Readers should keep the confidence limits visible. Zillow’s current index does not identify the rent of a specific bedroom count, ACS estimates carry survey uncertainty, HUD standards are administrative, and Redfin’s rolling resale window does not describe rental transactions. Before applying these screens to an individual property, verify the current asking rent for the exact bedroom count, lease term, utility treatment, unit condition, occupancy status, and any concessions; separately verify property-level sale records, list history, and active competing listings. Vacancy and rent-burden statistics describe aggregates, so neither can establish demand, affordability, or likely performance for one unit. Does the specific unit’s current lease and resale evidence fit these separate benchmarks?
