Came to this site in 2007. While I also predicted a crash during the run-up, I made an arbitrary valuation judgement that when SFH in Mira Mesa got below $400k, it was time to buy. We had an agent, went on a couple showings. Thankfully, I tried to find some data to backup my assumptions, this site gave me everything I needed, and put on the brakes. We waited until Fall 2008, though prices were still dropping, they were within historical norms and it was a good time for us. 5 years later, we were able to sell with a good profit -> down payment to our forever home.
