I left Seattle for rural KY. There is no income tax in Washington state but the sales tax is punitive. But when compared to the income tax in KY, I’ll take KY, and for another reason: My annual real estate taxes on 32 spectacular acres and a new home are almost identical to those for my friend in Washington for his single acre in a rural area (Maple Valley) PER MONTH.
Wolfe county is the cheapest. ( I just looked it up )
