@Log and
@wageslave23 the distinction I'm making between a "Bubble" and a "Housing Crisis" is the difference between an increase in prices driven by speculative motives and a supply/demand mismatch.
Speculative Bubble Looks Like: Speculative demand, a component of Total Demand, increases when enough people believe future buyers will pay more for houses than they can pay right now. Speculative demand drives up prices beyond inflation and in the absence of an upward change in Fundamental Demand or a downward change in Supply (e.g. population stays about the same and construction is merely sufficient to replace old homes). Lots of media attention is on the six-figure gains being experienced by middle class homeowners and landlords. Frequent comments about FOMO and worry about missing the opportunity before prices go up further. Lenders bending over backwards to qualify edge-case buyers (e.g. 3-6% down payments, weak tracking for the source of down payments). General public obsession about saving up down payments, remodeling, getting approved for loans, getting into the fanciest neighborhoods before it's too late, etc. as opposed to other investment opportunities.
Fundamental Supply/Demand Mismatch Looks Like: Something suddenly disturbs the market's equilibrium so there are not enough sellers, too many sellers, not enough buyers, or too many buyers. Examples: a natural disaster reduces the number of sellers or a baby boom increases the number of buyers or a war/depression forces household consolidation. The pace of new construction either can't keep up with the speed of the change or exceeds the speed of demand creation. The change has to be sudden, because eventually the demand imbalance incentivizes a change in the pace of new construction, in or out-migration from places with surpluses/shortages, household consolidation/formation, and decisions to invest in real estate or elsewhere. On a local scale, S/D Mismatches can be explained by the opening or closing of new large employers in small cities, demographic changes such as the migration of elderly New Englanders to Florida, and the trendiness of various activities such as beach sitting, skiing, urban amenities and living downtown, micro-farming, etc. but when the national statistics are moving we cannot rely on local anecdotes or one-place-to-another trends.
If anything defies the laws of supply and demand, it's this talk about under-building houses over the course of decades. Millions of people across generations would have to choose to miss out on enormous profits for that to happen. Legal restrictions can suppress supply to an extent, but economic theory suggests they'd only decrease demand for land with legal restrictions and increase the demand for land without them. The exact opposite has been happening, because the legal restrictions became a narrative to support speculative attitudes.
I'm sure in places like San Francisco, it may seem like there are not enough houses because of local factors. But this cannot explain national statistics because anyone with a small down payment for a place in SF could probably pay cash for a house in most other places - places with plenty of jobs and opportunities. So it's really that buyers are trying to get into a "hot" market where they expect to leverage future growth. I.e. if they are going to buy one house and have one job in either place, why put down 6% on a $200k home in Kansas City when they could put down 6% on a $2M home in SF? If you expect your home equity to double in either place over the next year (i.e. a 6% house price increase would do it), wouldn't you rather double $120k instead of $12K? Seen through this speculative light, choosing the KC house is leaving money on the table. That seems true even if living in KC makes more sense from a wage/COL perspective, which it does.
When lots of people are fighting to buy assets that don't make economic sense, we can say the demand is Speculative, not Fundamental.
The media falsehood is that there's suddenly a Supply/Fundamental Demand Mismatch, when we have close to the same national population and number of houses as existed in early 2020. How did a S/FD mismatch occur just in the past 3 years, causing prices to go up 31% nationwide, if the fundamentals didn't change significantly in those years compared to years in which housing prices rose in pace with inflation? I don't believe for a second that sub-4% mortgages and massive leverage opportunities in no-recourse states had nothing to do with it.
----------------------
Finally, I'll agree that Speculative Bubbles are bad for human thriving - arguably worse than Supply / Fundamental Demand imbalances. When the dot-com bubble imploded, a recession put many people out of work, ruined many retirement plans, and caused significant stress and misery spread across tens of millions of people. When the Real Estate Bubble 1.0 burst, it took down important financial institutions, wiped out more retirees, increased the national debt, and put more millions of people out of work. This current nationwide possible-Bubble has been particularly brutal because it priced low-earners out of houses and apartments in most areas, not just the most expensive metros. If it causes a recession, the lowest wage earners are likely to be the first ones to lose their jobs. All this pain, and for what?
Speculative Demand has also directed the designs of our homes and cities. Huge homes are the norm and people buy more than they need because of the cube-square rule and because people want to leverage as many square feet/meters as possible. Plus, they anticipate the "greater fool" who pays them double someday in the future will have to be a rich person who wants a rich person's house in a neighborhood of above-average size houses (and everyone in the game better stay above average!). Finally, why invest in walkable infrastructure if you're going to flip the house to semi-elderly workaholics in 2-3 years? It's seen like a waste of money to build a sidewalk in front of an investment, when the next speculator will price your house as a commodity, by the square foot. And if prices crash and you walk away from the loan, having invested in that shared community infrastructure would only increase the loss.
We might get off the speculative roller coaster and bubble economy by:
(a) getting government out of the business of guaranteeing mortgages - privatize Fannie and Freddie Mac,
(b) embracing remote work, thereby defeating the narrative that NIMBY rules = higher property values,
(c) requiring higher mortgage standards, such as higher minimum down payments or more verification primary mortgages aren't being used as rentals,
(d) developing technologies like 3D house printing that could reduce construction costs and increase the speed at which builders could respond to price incentives,
(e) increasing the timeframe for capital-gains-free home flipping, and raising capital gains taxes
(f) keeping inflation low for another decade,
(g) removing regulatory disincentives against housing density, new construction, and remods,
(h) demanding more livable neighborhoods, living and investing in them long-term, and refusing to buy bean field tract homes on half-acre lots as "investments",
(i) higher taxes on short-term rentals,
(j) actually trying to tackle urban blight problems that lead to sprawl, like mass addiction, untreated mental illness, and people who are unemployable because they plea bargained
A lot of these actions would prevent people from buying homes, some would put people out of business, and others would deflate property values, so I'm not optimistic about the prospects. But the list serves as a reminder of the incentive structure propping up Speculative Demand, and the odds of it being permanently overturned. If anything, we're more likely to get additional housing subsidies ostensibly aimed at poor people but actually having the effect of reinforcing the speculation narrative.
