I mean, the infrastructure alone is going to cause a huge problem. Water and sewer weren't designed for 2x to 3x the number of units in the area. I know there's already plans to redo most of the main lines in Austin due to deteriorating pipes, but this will put a huge stress on the water treatment facilities going forward if it's implemented in any drastic way.
I think I watched maybe 2 minutes of it the other day, but the argument that I keep hearing is HOME will lead to more affordable housing. Says who?! It's a grift backed by developers and realtors, and until you find a way to keep people from building luxurious tiny houses on their property and charging a premium, it's going to be the same problem but at a different scale. Scarce inventory, high demand, priced well above the market.
BUT, to refute the teacher argument up-thread, yeah, 220K might be high, but a lot of teachers are part of a dual income household, and can afford it. Plus, a down payment doesn't seem to be factored into this. They could be selling a house in the burbs and rolling the equity into a new place, which could drastically reduce the mortgage payments. Only downside is they're paying for 500MM of homeless funding and a train to nowhere in their taxes.
