If society thought of housing similarly to other large purchases like cars in that there was no expectation of profit, we would all be a lot better off.
Now what caused this housing as investment idea? I haven’t seen any research on this, but my guess would be as a form of forced retirement savings as it allows people to build net worth without the self-control normally required of saving. And the difficulty of that delayed gratification is really just human nature.
And you don't get margin called.
150x leverage means 150x cashflow burden from taxation (> 100%!) and also maintenance costs of the property.
