Anecdote: I lived in Austin from 2017 to 2021. My rent was always very cheap (my baseline is Brooklyn which I guess makes everything feel cheap. But my rent went up $50 for the first 3 years and then down $200 during Covid and I checked recently and my aptmnt is still the same price). Around the time I left everyone was buying up houses to rent and Airbnb. Very palpably felt the growing supply when it came to bnb's (the owners having a harder time competing for renters etc). It's hard not to be surprised in spite of the tremendous growth in that city
