In NYC I can tell you that the metropolitan area lost about 500,000 people since 2020, added ~20-30k housing units per year in that same time. The vacancy rate somehow dropped dramatically despite this and rents also rose dramatically. I've yet to see any good explanation for this, yet you'll still see people advocate for building more housing as the solution.

Simply using the rental vacancy rate as a proxy for supply and demand does not work, since there are lots of factors that can affect vacancies. One of then, as outlined in the article, is landlords keep units off the market to drive up prices.

The explanation is that there isn't enough housing to meet demand. That's it. Until there is, prices will keep going up even when building more units.

Landlords wouldn't be buying up a ton of units and renting them out at a profit if there was a glut of inventory, because it would be a terrible investment.

Or, accounting and tax law makes it less painful to keep units vacant than reprice them at lower rents.

Which is a thing we could change via something like Vancouver's vacancy tax.

Make it more in landlords' interest to reprice units lower, if the market has excess inventory.

There is never enough housing to meet demand. Once people have housing they breed, that drives up the population and housing prices once more: only now the world is more crowded and shittier. Without habitat control, it will always be this way.

This meme has got to go: there is little if any evidence to suggest that markets are functioning either in the specific case of housing in high COL areas in the United States or frankly most times anyone trots out the Milton Friedman trope on HN.

Markets fail, they get captured, they get distorted by accounting treatments, they generate cartels. They get technologically disrupted by new forms of cartel pricing that blow past existing regulations(e.g. TFA).

Capitalism sounds dope, I hope I live to see it. But the idea that supply and demand in the Econ 101 formulation is anything to do with the lot of say a person renting a flat in 2024 is silly and borders on insulting.

A lot of native New Yorkers live with a lot of family members or roommates, and these are the types of people who are most likely the move out. Meanwhile, the most likely people to move into New York are well paid young professionals who can afford more space.

Taking these numbers as given, the obvious explanation is latent demand. A lot of people who used to live five to a 900 sqft. New York apartment are now living 2 or 3 to an apartment instead. Probably the rent dipped briefly before soaring, yeah? People took advantage, and when leases are up, many of those people will presumably consolidate back with their families.

Very similar to the concept of "induced demand" (which is also really latent demand) with regards to highways. Build new lanes, people who were unwilling to drive before use the lanes, traffic delays stay the same (but with higher throughput, and therefore still a net positive, even if the money would've been better spent on trains).

[JamesBarney]

Landlords are not keeping units off the market to drive up prices. There are no landlords who have the pricing power to make that work. There is no landlord that can keep 10% of his inventory off the market to drive up rental prices 11%.

[HarryHirsch]

There is, however, in any market a small number of big players, all politically connected, who will conspire against newcomers building new units. A couple years ago stories about that "historic laundromat" in SF were making the rounds, that is very typical.
