A sharp split defines 94601 at the June 2026 endpoint: Redfin’s direct ZIP resale observation shows a $664,850 median sold price, up 11.46% year over year, while Zillow’s ZIP asking-rent index is $2,103, up only 0.93%. Annualizing that asking-rent index and dividing it by the resale median produces a 3.80% cross-source screening ratio. It is not a cap rate, net return, expected return, property yield, or measure of a specific home’s economics. The measured tension is therefore resale price momentum that is much stronger than the current asking-rent change, not evidence that either market will continue in the same direction.
Rent history is positive but uneven in pace. The one-year exact same-month annualized change was 0.93%, the three-year measure was 0.67%, and the five-year measure was 1.44%. Recent direction therefore confirms a longer positive rent path, and it modestly exceeds the three-year pace, but it does not match the stronger five-year average. Annualized monthly-return variability of 2.95% calls for moderate caution when using one current rent snapshot as a definitive signal. Separately, the maximum drawdown reached 3.97%, documenting a historical decline from a prior peak. Coverage is 100% across 88 observations and 87 consecutive monthly returns. Transparent national history-eligible ZIP discovery ranks were 2,096 for momentum, 1,523 for stability, and 2,140 for the balanced measure; lower ranks place higher and these are backward-looking discovery tools, not forecasts.
Zillow ZORI is a typical observed asking-rent index blended across rental types, rather than a median lease or a property-specific quoted rent. At $2,103, the ZIP index sits below the $2,614 Oakland city-context rent, the $2,895 Alameda County-context rent, and the $3,301 San Francisco-Oakland-Berkeley metro-context rent. Those city, county, and metro figures are wider geographic context only and should not be substituted for ZIP evidence. The gap reinforces that 94601’s current index occupies a different rent level from its surrounding comparison areas, but it does not identify the rent for any particular bedroom count, building type, lease term, or available unit.
The five-digit label 94601 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 the matched ACS 2024 five-year survey, median gross rent was $1,721 with a $60 margin of error. ACS median gross rent describes occupied renter homes and includes selected utilities, making it a different evidence universe from Zillow’s current asking-rent index. Zillow’s index is 22.2% above that survey median, a difference consistent with their differing populations, timing, and rent definitions rather than a direct contradiction. The same ACS ZCTA reports median household income of $72,359, an area measure that should not be read as the income of a prospective renter or owner.
The bedroom figures are modelled estimates, not measured bedroom rents. Scaling ZIP ZORI by the local HUD ladder produces monthly modelled estimates of $1,450 for a studio, $1,737 for one bedroom, $2,103 for two bedrooms, $2,687 for three bedrooms, and $2,785 for four bedrooms. The FY2026 HUD two-bedroom FMR/SAFMR standard is $3,604, so the ZIP ZORI is 58.4% of that administrative standard. HUD FMR/SAFMR is bedroom-specific and useful for its local relative ladder, but it is an administrative standard, not an asking-rent observation. The model is consequently a sizing device around the ZIP rent index, not evidence of achieved rent by bedroom.
A simple 30% required-income screen converts the current asking-rent index into $84,120 of annual income, compared with the ACS ZCTA median household income of $72,359; the arithmetic index-to-income result is 34.9%. This is not advice and is not an applicant qualification rule. ACS reports 10,647 renter-occupied households, of which 6,093, or 57.2%, had gross-rent burdens of 30% or more. Housing stock totals 17,631 units, and the ACS vacancy rate is 5.1%, including 504 units classified as vacant for rent. These aggregate counts and shares describe area conditions, not whether a particular advertised unit is vacant, affordable, utility-inclusive, or available on stated terms.
Redfin’s direct rolling-three-month ZIP resale evidence adds a liquidity signal that challenges the restrained rent change. It recorded 44 homes sold, a median 33 days on market, 123 active listings, and inventory of 53 homes. Months of supply stood at 3.6. Sale-to-list results were also strong: the average sale-to-list ratio was 106.99%, and 60.52% of sales closed above list price; 25.9% went off market within two weeks. Redfin describes the for-sale market rather than rental transactions, so these are neither rental comps nor evidence of landlord revenue. Still, the resale combination of price growth, short marketing time, limited supply, and above-list outcomes contrasts with the ZIP’s modest current asking-rent growth and prevents the screening ratio from being interpreted in isolation.
The evidence has separate clocks and definitions: Zillow measures a current blended asking-rent index, ACS measures surveyed occupied households, HUD supplies administrative bedroom standards, and Redfin tracks resale activity. Neither the ACS burden share nor the vacancy classification establishes conditions at an individual address, and historical rent measurements do not establish future outcomes. Property-level review should verify the actual advertised rent, bedroom count, included utilities, lease duration, concessions, unit availability, listing history, and the relevance of any comparable sale. It should also distinguish a sale’s transaction date and list price from the broader rolling resale statistics. The central unresolved question is whether a specific unit’s terms align with the ZIP’s current rent index despite the markedly firmer resale signals.
