Quick Answer

Why are people moving from Washington to Idaho?

Housing cost, sunshine, and pace of life. Washington home prices — particularly in the Seattle metro — have priced many buyers out. Idaho offers substantially lower home prices, 200+ sunny days per year, and a community pace that is meaningfully different from western Washington. The income tax trade-off is real: Washington has none, Idaho does.
