Mom...I have been doing this for many years and, for the most part, people involved in litagation are moved by economics with a bit of common sense thrown in. Not these major banks and their law firms that are called "foreclosure mills." It is hard for many of us to figure out the sense of some of their actions because, like your example, it makes no sense. Of course any business can write off their losses against their profits but anyone will tell you that every business wants more profits and would be happy to never take a loss. I seriously think that it just boils down to the banks are so big that there really is not anyone that can look at an individual situation and make an intellegent decision. They are guided by hard and fast rules that do not always apply to a specific case and that is why the outcomes sometimes seem very foolish.
