> And it is just supply and demand, and you've addressed supply but what is driving so much demand, and why do participants in that market have so much more money to be bidding up prices.
This is something a quick visit to Wikipedia will explain to you. [1]
> Since the 1960s, San Francisco and the surrounding Bay Area have enacted strict zoning regulations. Among other restrictions, San Francisco does not allow buildings over 40 feet tall in most of the city, and has passed laws making it easier for neighbors to block developments. Partly as a result of these codes, from 2007 to 2014, the Bay Area issued building permits for only half the number of needed houses, based on the area's population growth. [1]
They literally built half as many houses as needed.
> ... and why do participants in that market have so much more money to be bidding up prices.
That would be because of the number of high-paying jobs added in the Bay Area.
> At the same time, there has been rapid economic growth of the high tech industry in San Francisco and nearby Silicon Valley, which has created hundreds of thousands of new jobs. The resultant high demand for housing, combined with the lack of supply, (caused by severe restrictions on the building of new housing units) have caused dramatic increases in rents and extremely high housing prices. [1]
Remember, these are outliers as on average across the US, on an inflation adjusted basis, the $/sqft price of housing has not budged since the 1970s. However, zoning rules left the average new house twice as big outside of metros, and regressive policies in metros skewed the supply side of supply and demand.
Thing is, I'm frustrated because you're right to be mad but pinning this on the Fed is pissing into the wind. Put the blame where it's due: deregulate housing construction. Allow supply to grow to meet demand. It's not rocket science.
The only thing the Fed has done to raise the price of houses is decrease interest rates. A drop from 5% APR on a 30-year fixed to 2.5% APR means for the same monthly payment you can afford a house 25% more expensive. Fundamentally however this didn't change the affordability of housing for the borrower class.
The cantillon effect may account for some subset of this wherein wealthy borrowers with easy access to capital are able to take advantage of the lower price of housing (before bid up) and also the lower interest rates. However, I've found zero quantification of this.
