The way house prices work, often, is more or less banks determining prices via mortgage eligibility. Banks agree that a house is worth X. They lend X. That becomes the price. Buyers tend to be available.
People are so quick to see that credit expansion fuels price inflation in other areas, even the economy at large, but somehow diminish or ignore this with housing.
Obviously, supply constraints avoidable or otherwise, affect supply. In any given year though, the supply of housing does not change a ton. Where they do, you don't tend to have wild inflation... though you do often see bigger houses.
It's impossible to decouple housing from monetary policy. Housing is one of the few ways that buying power gets from A to B, where B is not a financial institution or direct spending.
There is a significant voice that would like to price cars out of private ownership. Traffic, pollution, safety, urban sprawl ... pick your evil and someone wants to eliminate private cars for that reason.
I regularly read about how the next wave of cars will all be somehow "shared", that we will whistle and they will appear at our doorsteps ready to carry us off to our 9-to-5 jobs in shiny glass office towers. I just don't see that happening anytime soon. Total conversion to electric cars in 10 years, maybe. Conversion to total ride-sharing and/or mass transit, doubtful in 30.
It has lost value against lots of commodities and "real" goods.
The wish to inflate housing prices causes NIMBY-ism!
I'd prefer it if ICE cars were as expensive as possible in order for the planet not to burst into flames.
