Wendy,
When you find something you're interested in, go down to the OC Tax Assessor's office and the Recorder's office and see what the status of the property is. On a property we were interested in back in December, a co-agent of the seller's that was assisting with the open house suggested that we make a low ball offer. There were a few things that made us unsure about the house, so we didn't rush to make an offer, but the agent's comment was so odd that I decided to do a little background check. It turned out that the seller's adjustable rate mortgage was about to reset to some ungodly amount (IIRC, about 11.5%). We were also able to find out how much they bought the place for, what they refinanced for, and any home equity loans. This allowed us to know how underwater the seller was (and the minimum they would have to sell for) and how distressed they were - i.e., how "negotiable" the price was. While we were doing the research, however, two other parties came in with full or near full price offers.
