But one question, considering you found those cheap houses in rural areas in Japan, why not invest in them?
You are already familiar with the environment and don't need to go international until you do it locally
Thank you for your comment. You are right. I'm actually considering buying one of them. I just wonder if it's also possible for foreign countries. It's also better if this scheme works in different legal zones with different armies with different set of political philosophy, because it's way harder for banks (and feds) to confiscate all of them.
After 5 years, if your house did not depreciate you can sell it and pay the bank (remember you've got an interest only payment type of deal)
Alternatively you can go for "repayment" type of deal but that increases your monthly costs and minimises your bitcoin investment.
Getting loans from bank is the most common way to get a house in Japan too. Damaged old houses can be valued in much lower prices than in western countries because we have a lot of natural disasters (hurricanes, volcanoes, earthquakes, tsunamis, and exploding nuclear power plants

), and people in Japan tend to avoid second-hand houses, so things are valued a bit differently.
I researched a bit about interest-only-payment without remaining debt, but Japanese banks rarely provide such loans for houses. Only government-backed funds provide such a thing, but it's almost like a welfare for old people. So, I have no choice but to select "repayment" type of deal.
Still, I don't like loans because I cannot tolerate associated risks in case the property gets devalued in an unmanageable way. You could lose everything and the loans could bite your other assets. Even if I could perform better with loans, I think it increases overall risks. I could be wrong here though.
I am not getting exactly what you mean by agents. I really don't believe in any so-called agents. I like straight forwards.
You are right and it's better to avoid agents if possible. However, in most countries it's only possible to write official papers in local language. So at least you need a help from translator. But if he (the translator) can also help find properties/customers and convert rent into bitcoin, it's much better (because less trust points are always better). I'm not sure how to exactly name such a profession though.
You may DM me or contact me through Telegram if in case you are interested. For advance info, your investment should be in fiat through a government bank. But your earnings could be sent through Bitcoin. It's because Bitcoin isn't legal tender here.
Thank you very much. I may contact you after my final decision. Sending out fiat investment to get earnings in bitcoin unnoticed is promising (perhaps grey) area of business for countries with limited access to bitcoin. It does not seem very popular, but in my opinion that's because they are just hiding under the radar.

If it's about pure investment in eCommerce platform development company stocks or something, I'm sorry to say that I'm not really interested in it now.
