bad credit zero down mortgage

How can you blame the mortgage-backed securities and Wall Street as guilty of over Freddie and Fannie?

Fannie and Freddie had not been mandated by our government to write subprime loans and risk, these securities are traded and sold have maintained their value. Furthermore, how these companies assets are not willing to write was overvalued have not yet been followed to write "zero down", "no credit, bad credit, no no problem "loans? Yes Please explain how Wall Street is more culpable than Freddie and Fannie. I am willing to learn.

You can not. The only way to know if ACORN working for them instead!
