For high earners, Washington's advantage grows (capital preservation).

Washington appeals to tech workers earning 6 figures, not to cost-conscious families.
Housing: Rent & Purchase Prices
Washington median home price ($550K) equals Colorado's, but costs more per square foot than most CA metros except SF/SD. Property taxes (0.97%) are highest in nation, offsetting lower purchase prices. For a $550K home, annual property taxes are $5,335 vs California's $4,125 (0.75% statewide avg). For homebuyers, Washington is expensive. For renters, no advantage to California.
