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.

If a minority has most of the wealth then the equilibrium supply may include a lot of supply of second homes, very large homes on large plots for the rich, properties sold at a premium based on how much they can extract from renters, and even investment properties occupied by nobody whilst still having insufficient small basic homes and dense housing.

Capital that could be invested in better serving the bottom half has to compete not only with the use of those resources to further enrich the rich but other investment opportunities.

If you want second homes to be used productively, just allow folks to list them on AirBnb for planned short-term rental. Long-term rentals are a total non-starter politically for second homes, since you obviously can't ethically throw out someone who regards that rental space as their home. But short-term is actually fine.

As for larger homes, people should be allowed to live in there as larger, extended family groups - a common pattern in non-Anglo cultures. Ban "single family" restrictions since they amount to unconscionable discrimination against such reasonable living arrangements.
