I think the other thing not mentioned here is that Austin saw a huge influx of home buyers in 2020-2024 - most everyone I met during that time that moved from West Coast bought at the high and left within 2-3 years after realizing they couldn't handle the crumbling infrastructure and hot summers. Many of them have been holding onto these properties and trying to rent. This only put more pressure on another group - those who bought properties specifically for short-term rentals (e.g. Airbnb). Those who did stay are see massive headcount reductions in tech industry. Meanwhile there are many natives who would love to live closer but are stuck with properties purchased in '21-'24 in Round Rock, Georgetown, San Marcos, Taylor, etc.
So IMO this a perfect storm of not just building housing supply (which is great - the best thing the city has managed to do in the past 15 years), but also significant demand correction.
As someone born and raised in Austin and a homeowner within the city - I am ecstatic about decline in rents and home values. Austin became what it is in part because it was affordable.
We have no nearby mountains, hot summers, poor infrastructure, poor politics, a heavily polluted coastline --> there was no reason for it's prices to be as high as they were.
