San Bernardino County is a rent-versus-carrying-cost screen rather than a clean price-momentum case. Zillow's county median home value slipped at its 2026-06 observation to $553,855, while median asking rent was $2,489 per month and supported a published 5.39% gross yield before expenses. Investigators should test property-level costs and rent durability; buyers relying on appreciation or unverified operating margins should be cautious. These are measured market-rent data, not subsidy standards.
HUD's two-bedroom FMR of $2,201 per month is a payment standard, not an estimate of asking rent; it should not be used to derive yield. The effective property-tax rate is 0.70%, a carrying-cost input alongside unspecified insurance, maintenance, and financing. FHFA's repeat-transaction HPI rose 1.23% in its annual 2025 series. It challenges Zillow's price direction, but the methods and vintages differ and cannot be combined into an appreciation rate.
Demand evidence does not resolve whether tenancy will absorb supply. Net tax-return migration was -3,043, and movers in had average AGI $2,383 below movers out; both warrant submarket and renter-income checks. Investor mortgages made up 9.86% of purchases, showing nonoccupant participation but not identifying cash bidders. In Realtor.com's 2026-06 MLS listing market, active listings were 5,846, median marketing time was 58 days, and 16.44% had price reductions. These are visible supply, marketing time, and seller concessions—not sale prices or proof of buyer demand.
Risk limits are substantial: modeled climate loss equals 0.47% of building value per year and inland flood is the dominant hazard, but a county model cannot establish parcel exposure or insurance cost. QCEW is annual covered employment at county workplaces, not resident employment, unemployment, or a forecast; Trade, transportation, and utilities is only the largest disclosed private supersector. Missing vacancy, lease-renewal, operating-expense, insurance, parcel-hazard, and closed-sale evidence prevents a property-level cap-rate and exit-value conclusion.
