Oh, and hey,
IF you want to make your landlord a wee bit uncomfortable while living up to your lease...
File a copy of your lease with the court as some sort of item associated with your landlord's foreclosure case. Then, compose a note that in essence says you plan to live up to your lease but are not too sure who should be getting rent money and you thus plan to give it to the clerk of court 'to hold on to'. File this as well. Then, take your rent money and give it to the court to hold. Not only is this perfectly legal it will at the very least force your landlord to drag themselves to the court to pick up the $$$, and who knows, they may choose to avoid the courthouse at all costs as they may have papers that need to be served on them and they might be trying to lay low. If it goes unclaimed you might be able to go back at some point in the future and recoup it as the property may have changed hands two or three times and a rightful recipient may be difficult to identify.
