Quick Answer
Why are people moving from Oregon to Idaho?
Tax savings, housing affordability, sunshine, and political climate. Oregon has no sales tax but significant income tax. Idaho adds no sales tax and has lower income taxes. Portland home prices have pushed many buyers to evaluate Idaho. The political culture difference is significant and intentional for most Oregon transplants who choose Idaho.
