Interestingly enough, something like 86% of Vietnamese people own their own homes...

In part it's because 70% of the population are farmers, and if you live in a rural area and pass a test on raising crops the government will just assign you a plot to farm.

I imagine home ownership is also very high in Japan, where they've had a negative interest rate and deflation for 25 years. Their housing bubble burst with their aged population explosion and the total population being in decline.
