@Amandeep H. yes this is a pretty good plan but I am not sure about buying property everyplace you live. As noted, China will likely not be possible. In Japan you can but you will have a difficult time getting a loan without being a permanent resident - but if you have lots of cash, it will not be a problem. I think you can own condos in Thailand but not the land.
If you haven't read David Greene's book on out of state rental properties, I would strongly recommend it. It will give you ideas on how to vet PMs and other "team members" that you will need. You can also reach out to the BP community to ask for recommendations and pros/cons of different agencies you have connected with. Not all PMs are crooks. You need to get past that belief first or REI is not for you.
Find a location where you want to invest first, then look for agencies, brokers, PMs etc in that area to help you out, but ask them good questions. I have been cheated by PMs before (1 even went bankrupt and never told me until I received all the keys and contracts in the post!), but I have good people in the areas I own in now, so being cautious is good.
