James A. Wiedemer. A Homeowner's Guide to Foreclosure: How to Protect your Home and your Rights. Dearborn, Dearborn Financial Press, 1992, paperback, orange, large pages, about 200 pages. This book was written shortly after the Texas real estate meltdown and savings and loan crisis at the end of the 1980s, and is rather sobering, with a lot of information about the dangers of deficiency judgments, which can even effect sellers of property with unqualified assumptions. In the mid 1990s, I was in a situation where I had sold a condo in Dallas by letting the buyer assume the mortgage withtout qualifying. When she defaulted three years alter, I was on the hook, potentially. I was eventually paid back through a bankruptcy. But this can be dangerous.
There is also discussion of FHA, VA and conventional workout -- but this is older than the current subprime crisis.
