Tracy’s Zillow ZHVI typical city home value is $688,734.51 and its ZORI typical observed market rent is $2,716.90 monthly, producing a 4.7% gross yield before every operating cost. ZHVI fell 5.3% year over year, which does not establish future direction. The Zillow value equals 5.69x ACS median household income, while annual ZORI equals 26.9% of income. These citywide affordability measures frame entry cost and rent capacity, not a property’s rent, expenses, financing, or return.
Tracy has 30,228 housing units; 35.0% of occupied units are renter-occupied, and the citywide housing-unit vacancy rate is 4.3%. ACS reports a $699,000 median value for surveyed owner-occupied housing and $2,478 median gross rent for surveyed renter-occupied housing; gross rent includes selected utilities. ACS describes occupied housing and differs in concept and period from Zillow, so the measures should never be averaged. Tenure and vacancy are citywide stock context, not evidence that a specific unit will lease quickly.
ACS shows 52.2% of renter households are rent-burdened. Single-family units represent 85.2% of housing stock and large multifamily units 5.9%; these ACS shares do not show purchasable inventory. Of vacant units, 399 are classified for rent, or 30.5%; vacancy reasons do not measure current listings. Population was 6.9% higher than in the baseline ACS vintage, but overlapping survey vintages mean this is not annual and boundary changes may matter. Median household income is $121,119, while poverty is 7.8% and unemployment 5.5%; these are descriptive demand constraints, not causes of housing outcomes.
At the county scope, San Joaquin County’s property-tax rate is 0.746%; this county figure is broader context and not a Tracy or parcel measure. At the metro scope, Stockton, CA jobs increased 1.79% year over year and metro for-sale supply was 3.5 months, offering labor and liquidity context without measuring Tracy. At the national scope, the Freddie Mac 30-year mortgage rate was 6.58%; this national financing benchmark is not a borrower quote.
Aggregation, incompatible measures, survey uncertainty, and timing limit underwriting. Zillow gross yield omits taxes, insurance, management, repairs, capital spending, utilities, vacancy, transaction costs, and debt service; ACS cannot fill those gaps. Property-level checks should verify purchase price, attainable rent and utility responsibility, lease and vacancy history, parcel tax, insurance and hazards, association charges, condition, deferred maintenance, permitting, and financing terms. Use address-level sale and rental comparables and a full cash-flow stress test rather than city, county, metro, or national aggregates.
