I’ll bet the new locks were put on the door before the naïve tenant even moved in. Put there by the criminal scam artist - “Realtor”.
Yep, and my thought on this is that the “realtor” is a fake working for the bank. Just a thought. Because the only people that could legally change the locks are the owners in the first part, since the property was in short sale.
Many horror stories. Have a bud in FL trying to sell his home, one he owns outright, and the idiots from Chase made a keystroke error in a foreclosure address on the same street— putting HIS place in “limbo”. Could not sell it until the county acknowledged and cleared it up which took forever and for which the moron bank (who could have been pursued, should have in my view) would not take responsibility. Idiots.
