> Warren Buffett likes to regularly point out that the Fed's rates act like gravity on stock valuations. The lower the rates, the less gravity. The same is largely true of how housing is affected by the Fed's rates. If you want to absolutely crush housing prices, push Fed rates back up to where mortgage rates are at 15-20% again. What that all really means is, the lower the rates, the more asset valuation inflation occurs. It's just that for amusingly convenient reasons (ie to pretend inflation is lower than it is), most economists like to pretend that asset inflation doesn't count as real inflation in their models.
I know what you're proposing will be very unpopular but I have an idea that will be even more unpopular: a federal property tax on land + buildings at (five percent of property valuation) per year. There will be absolutely no exceptions for anyone. Everyone must pay. This money will mostly go back to local governments, toward infrastructure and utilities (mass transit, water, electricity, fiber Internet, sewage, garbage collection, education, ... ideally automated as much as possible) and a portion will go to supplement VAT to pay for supplemental universal basic income (in addition to the freedom dividend) that more than covers the new property tax on a one bedroom somewhere in the continental United States (so not necessarily midtown Manhattan).
The key difference in what I propose is the lack of exceptions. Everyone must pay regardless of whether it is a strip club or a church. You don't pay, you get evicted within fifteen years or however long we decide. I recommend eviction should happen when unpaid taxes reaches 100% of property value.
My Hope is that this will absolutely crash the housing market and stop this irrational speculation in the housing market.
