California conditions vary by county, city, neighborhood, property type, price band, insurance availability, and property condition. Sellers and landlords should compare current competition, recent closed transactions, withdrawn listings, concessions, and the cost of required work. Buyers and tenants should use the same evidence to distinguish scarcity from overpricing. Market data must be paired with property-level inspections, disclosures, insurance, financing, title, and local due diligence.
