Bob's right on the money. I can add a couple more details.
The home was filed as Lis Pendens on 11/14/08. The challenge with our information systems it that on 11/15/08, the home could have been brought current on the mortgage and there's no issue. On the flip side, the owner's could have made no payments since then and be struggling to figure out what to do. Our next notification will be a notification of a foreclosure sale and finally a reposession by the lender. Typically, the time from Lis Pendens to foreclosure sale is 7 months (could be less if owner abandons the home or negotiates a keys in lieu of foreclosure, etc.).
The only way to know what is going on is to contact the owner or the trustee, but the trustee is limited in what they can legally tell you.
The bottom line is that you can spend a lot of time and energy on a home that has lis pendens filed and not get anywhere. It may be a better use of your time to work with homes that are already for sale and are in a short sale or foreclosed status.
