Here's where property law comes in.

If the bank can't produce the documents and the real owner of the loan can't be identified, the contract is null and void.

You've got to hand it to Congresswoman Marcy Kaptur (and Ohio which produces a lot of great Congresspeople.)

By telling a bank to "produce the note," a homeowner can delay foreclosure by forcing the lender to prove the suing institution is actually the same which owns the debt.

Now, the banks own sloth and disorganization (and inherent dishonesty) can be used against it.

Final word: The media (and Wall Street and its criminal partners in Congress and the former Bush White House) love to call these loans sup-prime.

Here's the old fashioned word: predatory. (less info)
