ZIP 94061 is both Zillow’s ZIP market identifier and a match to a Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The current Zillow ZORI is $3,600 per month. ZORI is a typical observed asking-rent index blended across rental types, so it is neither a signed-lease measure nor a bedroom-specific quote. For wider context, the Redwood City city-context rent is $3,949, the San Mateo County context rent is $3,760, and the San Francisco-Oakland-Berkeley, CA metro context rent is $3,301; those city, county, and metro values are not replacements for the ZIP observation. The level sits below the city and county context but above the metro context, making the later acceleration in ZIP asking rent more consequential than a simple geography-wide comparison.
History frames why this snapshot needs caution. Through June 2026, exact same-month ZIP ZORI change was 6.95% over one year, compared with annualized same-month changes of 4.44% across three years and 4.72% across five years. The recent direction therefore confirms the longer upward path and is accelerating relative to both longer comparisons, rather than breaking from them. Series coverage is 100%, providing a complete record across its stated history. Annualized variability in monthly returns was 2.75%, so the route to the current index has included nonuniform monthly movement. Separately, the maximum peak-to-trough drawdown was -8.13%, showing that a meaningful historical retreat occurred. Transparent national discovery ranks among history-eligible ZIPs were 236 for momentum, 1,154 for stability, and 213 for the balanced signal, with lower ranks stronger. These are backward-looking measurements, not forecasts or investment recommendations, and the variability and drawdown each limit confidence in treating a single current asking-rent snapshot as fixed.
Bedroom detail must remain modelled rather than observed. The FY2026 local HUD ladder scales the ZIP ZORI into modelled monthly estimates of $2,482 for a studio, $2,974 for one bedroom, $3,600 for two bedrooms, $4,599 for three bedrooms, and $4,767 for four bedrooms. These are not measured bedroom rents and should not be used as proof that an available unit commands any one of these figures. HUD FMR/SAFMR supplies the administrative, bedroom-specific ladder, rather than asking-rent observations; Zillow ZORI instead blends rental types in a typical observed asking-rent index. The apparent match between the two-bedroom estimate and the headline index follows the scaling construction and does not identify the bedroom mix represented by current listings.
Income and ACS rent data furnish a different, occupied-household lens. Annualizing the index results in $43,200, and the arithmetic 30% screen produces a required household income of $144,000. The ACS 2024 five-year matched-ZCTA median household income was $146,265, placing the asking index at 29.5% of that median. This screen is arithmetic, not advice and not an applicant qualification rule. In the same ACS survey, median gross rent was $2,845 with a $95 90% margin of error; it covers occupied renter homes and includes selected utilities. The current Zillow index is 26.5% above that ACS median but is not a current asking-rent series. Also within the ACS renter universe, 52.9% of households had gross rent burden at or above the screen threshold. Burden and the income comparison describe survey aggregates, not whether a particular household or unit is affordable.
The ACS housing profile adds supply composition, with equally important limits. The matched ZCTA had 13,838 housing units and a 7.5% vacancy rate; renters occupied 46.0% of occupied homes. Its structure inventory included 9,372 single-family units and 1,258 large-multifamily units. Redwood City city context had lower vacancy, while San Mateo County context had higher vacancy, placing the ZIP between them on that aggregate indicator. City renter share was higher than the ZIP’s, while county renter share was lower. Vacant-for-rent records are a category within the survey’s vacancy inventory, not evidence of a currently available, suitably priced, or appropriate unit. Nor does the aggregate burden result establish a unit-specific payment outcome.
Direct ZIP resale observations point to brisk for-sale conditions that cannot be collapsed into the rent series. In Redfin’s rolling-three-month ZIP resale observation through June 30, 2026, median sold price was $2,099,526, rising 9.07% year over year; 87 homes sold and median marketing time was 12 days. Redfin reported 41 homes of inventory and 1.4 months of supply. The average sale-to-list ratio was 106.57%, and 71.83% of homes sold above list. These are resale, not rental, signals: price, sales, marketing time, inventory, supply, and sale-to-list measures describe the for-sale market rather than rental transactions, rental comparables, or a property’s operating economics. Fast marketing and above-list outcomes support the characterization of active resale liquidity, but say nothing direct about the rent of an individual home.
Set against the rent evidence, the resale reading creates the central tension. The ZIP’s recent asking-rent acceleration and near-threshold income arithmetic coexist with a median sale price that is growing and displaying rapid resale turnover. Yet annualized ZIP ZORI divided by the Redfin median sold price is only a 2.06% cross-source screening ratio. It is not a cap rate, net return, expected return, property yield, or a measure of cash flow. Thus resale strength confirms an active for-sale signal while challenging any attempt to infer purchase economics from rent momentum, the ACS burden share, or one rent index. Different dates, populations, property mixes, and measurement rules remain embedded in this comparison.
Several limits define what this report can establish. Zillow provides a ZIP-level index, ACS provides a ZCTA survey of occupied renter homes, HUD provides an administrative ladder, and Redfin supplies a rolling ZIP resale observation; none converts into address-level rent, availability, expenses, or tenant outcomes. Property-level review would need the live asking rent, precise bedroom count, lease term, included utilities, availability date, and the address’s own recent rental and resale comparables, then reconcile those facts with the relevant source universe. The history is robustly covered but remains historical, while survey margins and cross-source timing prevent a precise unit valuation. Which evidence is actually address-specific enough to answer the decision at hand?
