Moreover, check the county records to see if the owner HELOC'd the property to kingdom come...another indication of cashflow problems.

I know how to check the WaltonPA site, but have yet to figure out how to check the above. Anyone have a link?

As for you Jychf -- we are in the same boat. We were actually served with foreclosure papers, too. We answered the foreclosure within 20 days (basically just a copy of our lease and contact info so the banks' lawyers would keep us in the loop and we would have some notice) but the papers weren't even filed for 90 days.
What I've learned in the process of all this is that the banks are dragging this process out. When it does finally reach the point of auction, the banks simply show up and bid the amount of the loan, take the house back, winterize it, and leave it sitting empty.
Until the foreclosure goes through, your landlord is still the owner, regardless of whether or not he's made a payment for over a year. Your lease is still enforced. Be grateful that at least you are going month to month at this point, and you aren't obligated to pay rent or buy out your lease in order to get out of limbo.
Of course, until these houses are actually sold at auction, the whole community is in limbo.
