Maybe half of us can stop making our mortgage payments?
Apparently the originating lender can bring the foreclosure suit even though they do not own the loan and that is maybe part of the problem? Their interest in it is making money from doing the foreclosure deal---not in recouping any money. It would then appear that they have little interest in renegotiating the loan---whereas the investors may find that renegotiation or a short sale is better for them in terms of eventually getting their money??? I'm not sure about all of the players in this.
