Google the real estate rules/property ownership laws of your intended foreign land. Then go visit for a vacation to:
1. Make sure you like the place/could live there
2. Find a real estate agent and start talking
I’ve got property overseas in 3 different countries; it’s cheap, easy to buy, and if needed, I could live in all 3 countries without worry.
In many places overseas you can buy a smaller 600-700 square foot condo/apartment for less than $20,000. That’s in a nicely sized city, like Chaiyaphum in Thailand, Suzhou in China, or Lido in the Philippines.
Nice if you can do it, but that’s just a twist on the “bug out location” scenario.
Remember how folks screamed (and are still) at the government about Katrina?
Gov ain’t gonna make that mistake again. If the SHTF, you can expect the obvious, most apparent government reactions that will play on the evening news to make it look like they’re doing something and in control.
That means:
some form of martial law, including:
rationing
travel restrictions
some kind of policy/workforce to deal with shut-ins and elderly
possible energy policies - very limited gas availability, conceivably having the electric grid offline for some hours of the day or night
Given these kinds of things, I don’t see the practicality of depending on foreign properties. It’s not like you would have six weeks to get your passport in order and arrange for some nice neighbors to watch you place and go to the drugstore to stock up on suntan lotion or something...
