for folks that want to set up a base in the usa but spend much of their time traveling, you can pick up a little house in a small town in southwest texas for under $25k.
a few advantages..........no personal income tax, very low property taxes, homestead exemptions reduce property taxes for some, minimal government to intrude in unincorporated towns (often no need for building permits), low insurance costs, minimal heating in the short winter week, chicken fried steak.
