Bob Diamond is another who has materials on this topic.
Quite frankly, I was able to sit through the free presentation (in person at REIA, but webinar is about the same), and I fiigured out how to do it without paying for any courses.
When you come across people who have been in this predicament, they are sometimes more responsive - since selling is one of the few real ways to stop their "unstopable foreclosure" (that was the guru term for this). I have also come across some who were still dragging things out, and at least one who has gone into a fresh bankruptcy as well; so some still stubbornly hang on and refuse to sell.
