I’m reminded of this quote:
> Landlords grow rich in their sleep without working, risking or economizing. The increase in the value of land, arising as it does from the efforts of an entire community, should belong to the community and not to the individual who might hold title.
Look instead to the people who own golf courses, sports stadiums, super yachts, private jets and the like.
In addition, a 90% tax on real estate income (rental income minus costs like mortgage, interest, maintenance, property taxes, etc) would also disincentivize people who buy properties just to rent them out.
They are risking. Land value can go up or it can go down. It just has been mostly going up (in real terms) in the past decades, but it's far from certainty. You can lose money by investing in real estate, just like in everything else.
The question is who, if anyone gets the million bucks, that she didn’t pay for or earn, when the house is sold.
