Washington housing market
Washington, the Evergreen State, has a strong housing market, the sixth most expensive in the country, led by the Seattle metro which now is the sixth most expensive region in the United States. With Seattle-area companies growing rapidly, expect the crunch to only get worse unless housing supply or demand changes meaningfully. While it's hard to predict the future of the housing market, it's likely that Washington will continue to lead the country in apple, hops, and cherry production.
