yeah you're going to need to provide a source for such a ridiculous claim. My grandmother has owned her house for much longer than that.
* edit: all you downvoters need to look at the claim being made instead of bringing up different issues. credit cards are not mortgages. "couldn't sign" is not the same as "needed a cosigner" or "discounted rates". the original claim implies that women could not own houses through a bank loan, which is very much false.
