> I'm imagining a scenario where two iBuyer companies try to outbid each other algorithmically, driving the prices further and further out of reach of people who are looking for a primary home.

This is just my personal anecdote but... I'm pretty sure when I was rushing to show up to "new listings" on the weekends and waiting in line for 10-40 families to get a walkthrough "open house" wise, I feel like the sellers were going to pick a family that showed up over a Zillow website. What % of closed houses were being bought by families instead of "iBuyers" as you said it?
