Alameda County presents a high-cost entry decision: measured market-rent growth is positive, yet both supplied price indicators are negative in their distinct observations. Buyers able to verify building-level costs and durable rental demand should investigate; those relying on near-term appreciation or a thin carrying-cost margin should be cautious. In Zillow’s county reading for 2026-06, median home value fell 3.40% year over year. FHFA’s 2025 repeat-transaction HPI fell 1.91% year over year but was 23.27% higher over five years. Those methods and vintages cannot be averaged into a single growth rate.
The supplied Zillow county reading also reports median asking rent of $2,895 per month, up 4.85%, and a gross yield of 3.23% before operating costs. HUD’s two-bedroom FMR is $2,912 per month; it is a payment standard, not an asking-rent estimate. Market rent equals 99.40% of that FMR, a calculation that does not substitute FMR for rent. The reported effective property-tax rate is 0.78%, a carrying-cost input not reflected in gross yield. This supports preliminary income screening, not a conclusion about net cash flow or a property-specific tax bill.
QCEW annual covered workplace employment fell 0.86%, while average weekly wage rose; this is workplace evidence rather than resident employment or unemployment. Realtor.com MLS evidence shows active listings down 12.44% and 13.62% of listings price-reduced: visible supply and seller concessions, not closed sales or proof of demand. Net migration was negative 7,659 households, with out-movers’ average income $7,715 above in-movers’. Investors made 899 of 10,288 purchases, or 8.74%, making them a measurable buyer cohort without establishing their influence by submarket or property type.
Earthquake is the dominant hazard. The modeled annual climate-loss ratio is 0.41% of building value, but it is a modeled measure rather than a parcel-level earthquake loss or insurance quote. No insurance pricing, parcel hazard detail, vacancy, operating expenses, loan terms, property condition, lease roll, or closed-sale data is published. Those omissions prevent underwriting net yield, hazard-specific carrying costs, renter retention, financing sensitivity, and exit value; they also limit the county evidence to initial screening.
