Austin’s Surge of New Housing Construction Drove Down Rents

After decades of explosive growth, Austin, Texas, in the 2010s was a victim of its own success. Lured by high-tech jobs and the city’s hip reputation, too many people were competing for too few homes. From 2010 to 2019, rents in Austin increased nearly 93%—more than in any other major American city. And home sale prices increased 82%, more than in any other metro area in Texas.

Its wild how the solution to housing costs is really just:

Build more housing. Keep law and order.

No it doesn’t need to be “affordable”. Yes rent control is a terrible idea.

Just build more housing.

Note: that the US already has plenty of housing and housing costs basically go up in areas of low crime relative to economic opportunity. If you build housing, but allow crime to rise, you have wasted everybody’s time.

New construction has already decelerated in Austin due to falling prices, which compresses already-near-zero margin on real estate development.

So yes, it really is "just build more housing." The problem is: why would you build more housing as prices fall?

I'm confused by this objection, if you draw a stereotypical supply and demand curve, you can see how prices settle to an equilibrium point. Of course reality has more complications, but I think your objection is 95% answered by a supply and demand curve. You keep building houses when it is profitable. You stop when it is not. This naturally keeps everything in balance.

Free markets for housing are likely to settle into an "optimum" where some percentage of people cannot afford housing at all, because while construction/rental of housing for them would net a return, it's not worth the opportunity cost. Plus you should not wait for the market to respond to a lack of housing: people will be homeless in the meantime. Supply/demand is mostly reactive, because building for anticipated future demand years down the line is very risky, so most investors don't like that.

Markets don't optimize for "everyone gets some", yet that's precisely what you need for housing. You'll always need the government to come in at some point to provide for those left behind by the free market.

The trick is to acknowledge the market as the main mechanism at play, and have the sense to work around the margins. When the tinkerers get too enthusiastic, they tend to do more harm than good.
