Resale pricing and asking-rent direction diverge in 94541. In Redfin’s direct rolling-three-month ZIP resale observation, the median sold price was $849,808, up 4.27% year over year. At the stated Zillow endpoint, however, ZIP ZORI was $2,601 and down 0.30% from a year earlier. Annualized ZIP ZORI divided by the median sold price produces a 3.67% cross-source screening ratio, not a cap rate, property yield, net return, or expected return. The comparison places a cooling asking-rent reading beside firmer observed resale pricing, without establishing that either measure caused the other.
The five-digit 94541 label is both a Zillow ZIP market identifier and a matched Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow’s ZIP ZORI is a typical observed asking-rent index blended across rental types, rather than a lease comp for a specified unit. For wider context, Hayward city context rent was $2,614.80, Alameda County context rent was $2,895, and the San Francisco-Oakland-Berkeley, CA metro context rent was $3,301. The ZIP index therefore sat nearly level with the city context while remaining below the named county and metro contexts, which are wider-area comparisons rather than ZIP substitutes.
The backward-looking rent path shows a recent break from its longer expansion: exact same-month change was -0.30% over one year, versus annualized gains of 0.44% over three years and 2.15% over five years. Annualized monthly-return variability was 2.79%, indicating that month-to-month index movement has not been negligible and that one current rent snapshot deserves measured confidence. The maximum drawdown was 3.29%, a separate measure of the largest historical decline from a prior peak. History has 100% coverage. Transparent national discovery ranks were 2,430 for momentum, 1,218 for stability, and 2,239 for the balanced measure, where lower ranks are higher. These are retrospective measurements, not forecasts or investment recommendations.
Source scope explains part of the apparent rent gap. The matched Census ZCTA ACS five-year survey reports median gross rent of $2,239 for occupied renter homes; it includes selected utilities and is not an asking-rent series. ZIP ZORI was 16.2% above that survey median. HUD FMR/SAFMR is instead an administrative, bedroom-specific standard, not asking rent. Scaling ZIP ZORI with the local HUD ladder yields modelled monthly ZIP estimates of $1,793 for a studio, $2,148 for one bedroom, $2,601 for two bedrooms, $3,323 for three bedrooms, and $3,444 for four bedrooms. They are modelled estimates, never measured bedroom rents. The two-bedroom estimate equals 72.2% of the $3,604 HUD standard, a comparison of unlike rental benchmarks rather than proof of a unit’s market rent.
The 30% required-income screen converts the current asking-rent index into $104,040 of annual household income, compared with ZCTA median household income of $105,729. That arithmetic places the index at 29.5% of median household income, but it is not advice, an applicant qualification rule, or evidence about any household’s actual budget. ACS burden data add a separate occupied-renter perspective: 5,638 of 11,507 renter households, or 49.0%, reported paying 30% or more of income toward rent. Those survey results describe a population distribution; they do not prove burden, affordability, or utility costs for a particular available unit.
The ACS ZCTA housing base contained 22,934 units, with renter-occupied households comprising 53.3% of occupied homes. Its 5.9% vacancy rate is a stock-wide survey measure, not a real-time availability count. Of the vacant units, 607 were classified as for rent, while the broader stock showed a single-family emphasis relative to large multifamily buildings. This combination provides context for the renter base and housing structure, but neither the vacancy figure nor the for-rent count establishes vacancy, pricing power, condition, or lease terms at an individual property.
Liquidity signals within Redfin’s ZIP resale universe were active: 71 homes sold, median marketing time was 20 days, inventory was 81 homes, and months of supply stood at 3.4. The average sale-to-list ratio was 102.64%, while 50.77% of sales closed above list and 44.01% went off market within two weeks. These are direct for-sale observations only, not rental transactions or rental comparables. Together with the higher median sold price, they confirm a price-side signal that challenges any attempt to treat the cooling ZORI reading or the income screen as a complete description of the local housing market. They cannot convert the rent-price screen into property economics.
Several limits should frame a decision using this ZIP report. Zillow’s blended asking-rent index, ACS gross-rent survey, HUD administrative standards, and Redfin resale records each observe different populations and time constructions. ZCTA boundaries also do not recreate USPS delivery geography. Property-level review would need current unit-specific asking rents by bedroom, lease concessions, utility responsibility, condition, vacancy status, and comparable advertised rentals; for a purchase or resale question, it would also need sale comps, list-price history, property condition, ownership costs, and any transaction-specific constraints. The unresolved question is whether those property facts align with the ZIP-level cooling rent path and the separate resale evidence.
