If it were me, I would have just passed a federal tax on property where whatever the local city, state, and county taxes are, there's also a federal levy of property taxes of the exact same amount multiplied by the number of properties each taxpaying owner owns - 1.

So if you own one home, you pay no additional taxes.

If you and your spouse own two homes, you pay no additional taxes.

But if you own five 1 million dollar properties as a single person and the property taxes on each of those properties is $5,000, then instead of paying a total of $25,000 in property taxes as a single homeowner, you would pay

$5,000 * 4 * 4 + $5,000, or $85,000/yr.

That $60,000 a year difference for being a multiple homeowner would go into a fund specifically to provide grants and assistance for low-income renters and first-time homebuyers.

This would make it so that owning multiple homes becomes a sign of affluence.

And it would put a steep price curve on going over the limit of even moderately reasonable amounts of homes to own as a person.

Adding one additional $1 million home with a $5,000 property tax annual on it would actually add another $45,000/yr to the taxes that you would pay compared to someone who only owns that single home, and doing it this way, make sure that the scale of increasing taxes that you would pay on home ownership would become exponentially prohibitive.

It would also ensure that at a very reasonable point, no matter how much you charged for rent, for any property you own, once you own more than four, it becomes impossible to actually profit off of multiple home ownership, because very quickly, no renter in the universe would pay what you need to earn in order to cover the taxes off of owning that property.

This is part of my pitch to become president in 2032 when I become eligible.
