Berkeley’s current Zillow ZHVI is $1,478,916, while Zillow ZORI is $2,941 per month. Their implied gross yield is 2.39% before every operating cost, financing expense and vacancy loss. Affordability is tight on the supplied cross-source comparisons: ZHVI equals 13.68x ACS median household income, and annual ZORI equals 32.65% of that income. These are city-level screening measures, not a property cash flow or mortgage qualification.
The city has 53,145 housing units; 55.81% of occupied units are renter-occupied, and the citywide vacancy rate is 11.31%. That tenure profile supports evaluating rental demand, but neither measure predicts lease-up for a specific unit. ACS reports a $1,413,900 median home value among surveyed occupied owner housing and $2,133 median gross rent, which includes selected utilities. Those ACS measures cover different housing and periods from Zillow’s typical value and observed market rent, so they should not be averaged or treated as interchangeable.
Citywide, 55.66% of renter households meet the supplied rent-burden threshold. Single-family units are 43.86% of housing stock and units in large multifamily structures are 20.13%; these shares describe structure mix, not available investment inventory. Of vacant units, 47.84% are classified for rent, but that does not establish market-ready supply. Population was 1.01% lower between overlapping ACS vintages; this is not annualized and may include boundary-change effects. Median household income is $108,092, while poverty is 17.26% and unemployment is 5.58%; these are descriptive demand constraints, not causal or tenant-level findings.
In Alameda County, the FHFA house-price index was down 1.91% year over year; county Realtor context shows 32 days as median market time and 13.62% of active listings with price reductions. These county measures describe the surrounding market, not Berkeley transactions. In the broader San Francisco metro, jobs rose 0.09% year over year and metro building permits totaled 7,708, offering labor and supply-pipeline context without measuring city demand. The national Freddie Mac mortgage rate is 6.58%, a financing input rather than a city housing metric.
The main limitation is that a citywide Zillow gross yield excludes taxes, insurance, maintenance, management, utilities, capital work, transaction costs and financing, while ACS stock and household statistics cannot identify a building’s condition, legality or achievable rent. Before underwriting, verify the subject property’s purchase basis, current and comparable leases, unit occupancy and turnover, property-tax bill, insurance quote, utility responsibility, association charges, inspection findings, deferred work and financing terms. Also review title, permitted use, lease records and applicable operating restrictions; these checks determine whether the city-level screen survives asset-level diligence.
