In the past, the Government did not want Banks to be Property Owners:
They were discouraged and actually penalized for holding on to them too long.
Right now, it seems as though that is not the case:
We suspect that the Banks are holding a "shadow inventory" of homes, waiting for the Market to recover before they release them. Estimates vary; and probably no one knows how many.
Is this "price fixing" ? probably not, because there is no "collusion"; is there?
