You obviously need to take a Economics 101 course.
Vacant, boarded homes are a physical and economic blight on any neighborhood. They devalue EVERYBODY's home. The only help these people who are upside down in their mortgages is government intervention
People who are liquid will be able to take advantage of the inventory glut. Right now, it's 'investors' with cash who are buying bank/REO properties before they even reach the papers.
I know of one who services the network of the largest law office that specializes in going after people behind in their mortgage or condo/HOA fees. He's purchased 3 of them already this year.
What's a "foll?" ;-)
