For Vallejo, Zillow’s typical city home value is $526,808 and typical observed monthly market rent is $2,181. Those measures imply a 5.0% gross yield before management, maintenance, insurance, property tax, vacancies, financing and capital work. The Zillow value equals 5.84x ACS median household income, while annual Zillow rent equals 29.0% of that income. This is a screening frame, not a property return or a borrower-specific affordability test.
The ACS city survey reports 47,084 housing units, a 4.9% vacancy rate and a 42.6% renter share, framing the breadth and tenure of the stock rather than the availability of purchasable rentals. Its $589,500 median home value covers surveyed owner-occupied housing, while its $2,073 median gross rent covers occupied rentals and includes selected utilities. These ACS measures differ in population, method and period from Zillow’s typical value and observed market rent, so they should not be averaged or treated as direct comparables.
City depth is mixed: 61.6% of renting households are rent-burdened, while single-family homes are 73.0% of units and units in large multifamily structures are 8.1%. Among vacant units, 24.4% are listed for rent; that is a reason share, not a count of investable or immediately rentable properties. Population rose 2.5% between overlapping ACS vintages, which is not annualized and may reflect boundary change. Median household income is $90,171, with poverty at 12.2% and unemployment at 7.4%; these describe demand constraints but neither cause nor predict property performance. None of these citywide facts establishes lease-up speed for a specific unit.
At the county scope, Solano County’s listings had a 43-day median market time and 18.7% of active listings were price-reduced, signaling room for listing-level diligence rather than a Vallejo result. In the broader Vallejo metro, employment grew 0.5%, months’ supply was 3, and 28.3% of listings had price drops; those metro indicators do not measure the city alone. The national Freddie Mac mortgage rate was 6.66%, a financing benchmark rather than a quote for any borrower.
The main underwriting gaps are property condition, achievable unit rent, operating expenses, insurance terms, taxes after transfer, financing, legal use, tenant status and near-term capital needs. Before acting, verify comparable leases and sales, inspect major systems, obtain insurance and loan quotes, read title and disclosures, confirm permits and zoning, and build a property-specific cash flow with vacancy, concessions, management, repairs and reserves. Citywide vacancy, renter share and survey structure data cannot substitute for those checks.
