Some. Not like Michael Burry. Starting with seeing what was going on in my South Florida neighborhood, and seeing Robert Schiller's graph of house prices vs. income in the NYT in 2005, I did a bunch of research, leading to selling one house in 2005, and another in 2007. I made money on both. Those buyers each later lost money when they sold the houses. On balance, I made some money, and lost a lifestyle. I don't think of myself as a winner there. There was plenty of signal. Given the havoc caused in so many people's lives across the world, and given the documentation now available, I don't think 'No one could have seen it coming' is a reasonable way to think about what happened.
Hindsight is 20/20. From what I can tell, the Case-Schiller index is back around 2005 levels, even higher in some cities like LA. [1] Should people start selling their houses?
Could you point out the hindsight? What's different since 2005, in my perspective, it that it is now clear that there has been no political will to let bad loans go bad (evidenced by the government's responses since 2009). If you expect that to remain the case, it makes sense to not sell. If you expect that to change, and that house prices should go back to their historical income ratios, then it makes sense to sell.
