credit cards are non secured debt. they cannot foreclose on property not pledged to support the debt. They can sue you personally, if you guaranteed it, or sue your business, but they cannot take the property.
The other answers, while normally correct, have not be the case on matters we have actually handled, where the 2nd foreclosed but owners was allowed to stay due to deal with 1st. It just happened that way actually.
Absolute, absent fraud, there will be an automatic stay in effect upon the legal filing of a chapter 7. You must be sure to serve notice to all parties concerning, including not just the lender, but the servicer, and the sheriff, that an automatic stay is in existence.
Interesting question. Normally you have only 5 days to respond and request a hearing. Normally, posting the notice on your door is sufficient and there is no absolute need to receive a letter. However, with nothing showing with the court, you raise serious credibility questions here. With 23 days gone, I would immediately file a response with the court and request a hearing date. Be interesting if your filing beats theirs to the courthouse.
B of A is the worst. Never rely on their word. They make and break promises every minute. Unless it is in writing and signed by someone with authority, their word is absolutely worthless. That is why we sue them almost everyday.
We sue lenders every single day. Misrepresentation and Fraud are major reasons for doing so. I see actions by lenders regularly foreclosing while denying doing so. It would be a worthwhile thing to consider.
Filing for BK relieves you of the right to answer, due to the automatic stay imposed by the bk court. However, the others who did not file bk must file an answer within 5 days for the ud will require them to promptly leave.
