Thank you for all the comments. Whether I agree or disagree, it is very helpful to see different views and opinions.
Having read all the comments, I will try to make myself clear for your interest. Above all, I want to avoid earthquake risk. In Japan, wherever you live, you have chances to encounter earthquakes. I live in the greater Tokyo area. I would not be surprised if a big earthquake should hit us tomorrow. Within 30 min drive locations, I could buy a tiny one room condo under $100k. To buy a house, you have to spend at least half a million dollars. So none of these is my option due to risk management and financial limitations.
To me, US real estate market is attractive because unlike Japan, US population is growing and housing needs are solid. I know US more than other countries and have had a Waikiki condo for five years. I do tax return myself. If I could buy a wooden structure house +22 years old, that would enable me to depreciate the construction value in four years in the Japanese tax law. I will work as a salaried worker for a few more years. This depreciation works to reduce my income tax even though I do not earn much now.
I know US real estate price is going up. I understand from my experience that you have to pay more if you buy later. I do not mean to wait forever. But US economy expanded more than seven years. That's exceptional. Considering political unstableness and stock market uncertainty, I would not have to dive into the market now. I need to have much more serious thoughts if I decide to buy something.
Last but not the least, turnkey service companies are a viable option for me. I have to pay more but I do not have to go through all the troubles to buy, fix, rent and manage. I know a company - Memphis Turnkey. By knowing them, I thought Memphis or similar cities would be worthwhile looking into.
I would appreciate input from remote landlords who have rental properties in states where you do not live.
Mahalo.
