Napa County, CA

Napa County poses a carry-cost and liquidity tension: Zillow’s 2026-06 county median home value was $885,567, with a lower year-over-year direction, while the FHFA repeat-transaction HPI fell 1.02% in its separate 2025 annual observation. This warrants scrutiny from buyers relying on appreciation or short resale windows, but does not establish a sale-price trend: Zillow is a value measure and FHFA an index, with distinct methods and labeled periods. Income buyers should test rent against taxes, insurance and flood mitigation.

Zillow’s median asking rent was $2,815 per month, yielding the supplied 3.81% gross yield before costs against its median value. This is market rent, unlike HUD’s $3,315 two-bedroom Fair Market Rent payment standard; it cannot be used to impute rent. The 0.69% effective property-tax rate and $5,995 median annual tax make carrying-cost review material. Gross yield does not show net operating income, debt coverage, insurance, repairs or vacancy.

Realtor.com’s 2026-06 MLS evidence shows active supply declining year over year, 73 median days on market, lower asking-price direction, and 14.83% of listings reduced. Its 19.58% pending-to-active ratio is listing status, not proof of buyer demand or closed prices. Tax-return migration was net negative by 369 households, although incoming movers’ average income exceeded outgoing movers’ by $42,677. Investor participation was 10.60% of recorded purchase mortgages, so non-owner competition exists but is not the majority indicated by this measure.

Inland flood is the dominant hazard. The published climate-loss ratio is a modeled annual share of building value, not a property-specific loss estimate; obtain parcel flood zone, elevation, insurance quotes and mitigation history. QCEW reports annual covered jobs at county workplaces, not resident employment or unemployment; its average weekly wage is a covered-worker average. Manufacturing is its largest disclosed private supersector, not the whole economy. Its employment decline alongside wage growth is mixed. Missing vacancy, operating expenses, insurance, debt terms, sale comparables, lease turnover and parcel hazard data prevent net-yield, debt-service, resale and insurability conclusions.
