I live in Spokane and answered Idaho, However, I don't think you can make the decision on hunting alone unless you are retiring. If work plays into the cards, then you need to consider income tax in Idaho, ability to find work, and a few other factors. To speak to the ability to find work, unemployment in Boise was higher than Spokane by quite a significant number a year ago, mainly due to a few large employers, which trickled down to the entire community. I don't know if that has changed in the last year, but make sure you do some homework on the community.
With all that said, there were some smoking deals on foreclosures / short sales in Boise / Nampa over the last couple of years.
