ZIP 94538 presents a measured split between advancing asking rent and softer resale pricing. Zillow’s current ZIP asking-rent index is $3,122 per month, up 3.9% from the same month a year earlier, while the Redfin ZIP median sold price is $1,289,709, down 11.4% year over year. Those directions describe different evidence universes rather than a single market verdict: the former is rental asking-rent evidence and the latter is for-sale evidence. The contrast challenges any simple reading of current rent strength as confirmation of resale pricing, affordability, or a forward outcome.
Backward-looking Zillow rent history shows a one-year exact same-month change of 3.9%, a three-year annualized change of 2.4%, and a five-year annualized change of 3.8%. Recent direction therefore confirms the longer positive path while running faster than the slower three-year pace. Annualized monthly-return variability of 2.2% indicates relatively limited month-to-month movement in the observed index, which supports somewhat more confidence in the current snapshot than a highly volatile series would. Separately, the maximum drawdown was 5.7%, documenting that declines still occurred. Coverage is 100% across 116 observations. Transparent national discovery ranks are 939 for momentum, 314 for stability, and 304 for the balanced measure among history-eligible ZIPs, where a lower rank is higher; they organize past measurements and are not predictions.
The five-digit label 94538 is both Zillow’s ZIP market identifier and a Census ZCTA match. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow ZORI is a typical observed asking-rent index blended across rental types, whereas ACS median gross rent is a five-year survey measure for occupied renter homes that includes selected utilities. The matched ZCTA’s ACS median gross rent is $2,860, with a $63 90% margin of error, so it should not be substituted for the current asking-rent index. HUD FMR/SAFMR is instead an administrative, bedroom-specific standard, not asking rent. Scaling ZIP ZORI by the local HUD ladder produces modelled monthly estimates of $2,153 for a studio, $2,579 for one bedroom, $3,122 for two bedrooms, $3,988 for three bedrooms, and $4,134 for four bedrooms; these are modelled estimates, never measured bedroom rents. The FY2026 HUD two-bedroom standard is $3,604.
At the current ZIP asking-rent index, the 30% required-income screen equals $124,880 annually. Against the matched ZCTA’s $147,301 median household income, the simple asking-rent-to-income calculation is 25.4%. That screen is arithmetic, not advice and not an applicant qualification rule. The ACS burden measure adds a separate retrospective household perspective: 5,681 of 13,057 renter households, or 43.5%, were estimated to pay 30% or more of income toward rent. Neither the income comparison nor the burden share establishes what a particular household can pay or what any individual unit will cost.
The matched ZCTA contains 24,854 housing units, of which 1,226 were vacant, producing a 4.9% vacancy rate. Renters occupy 55.3% of occupied homes, making renter households the larger tenure group in this statistical area. The structure mix includes 13,015 single-family units and 7,681 units in larger multifamily buildings, while 682 vacant units were classified as vacant for rent. These stock and vacancy counts frame aggregate supply conditions, but they do not establish current availability, lease terms, condition, or pricing for a particular rental home.
Broader figures remain context only: Fremont city-context rent is $3,308, Alameda County context rent is $2,895, and San Francisco-Oakland-Berkeley metro-context rent is $3,301. The ZIP’s direct asking-rent index is therefore below the named city and metro context values but above the county context value. These city, county, and metro comparisons use wider geographies and cannot replace the ZIP asking-rent index, the matched ZCTA survey results, or property-specific evidence. Their main use here is to show that the ZIP’s rent reading sits between its county context and its city and metro contexts.
Redfin’s direct rolling-three-month ZIP resale observation supplies the for-sale side of the tension, not rental transactions. The median sold price was $1,289,709 after an 11.4% annual decline; 90 homes sold with a median 18 days on market. Inventory was 83 homes, up 29.4%, and months of supply stood at 2.8. Resale-liquidity signals were still active: the average sale-to-list ratio was 102.9%, and 55.7% of sales closed above list. Annualized ZIP ZORI divided by the median sold price equals a 2.90% cross-source screening ratio only, not a property-specific economic measure. Falling sold prices challenge the positive rent history and income screen, while the marketing and sale-to-list signals caution against treating the price decline as a complete description of ZIP resale conditions.
The central limitation is that each source measures a different population, time frame, and transaction stage. ZORI tracks asking rents, ACS reports surveyed occupied renter homes, HUD sets administrative standards, and Redfin records completed ZIP resale activity. A property-level file would need live effective asking-rent comparisons for the exact bedroom count, concessions, included utilities, lease duration, unit condition, and availability date. It would also need sale comparables matched for sale timing, property type, condition, and listing-to-closing details. The useful question is whether those direct property facts align with the aggregate rent, burden, stock, and resale signals rather than whether any one series can answer every rental decision.
