IMO the general point is that real estate prices are severely inflated relative to other things & in addition to the possibility of a relative price adjustment in coming years there is also a non-zero risk of serious political instability. So the potential of incurring a total loss is much higher than at times in the past. Sound money (#bitcoin) is the right investment in times of uncertainty. I think there is also a bit of an airbnb bubble too, but certainly when it comes to cash flow the right sort of real estate can make a lot of sense.
