Wait. What? Hmm. Scare tactic of the grunge collection machine.
Okay, responding to prior post to say that filing a chapter 13 at any time, including the day of the sale,will protect you. With that you can file an adversary complaint if you need to prevent the sale. However, its a ton of paperwork and you want to have access to everything for, at minimum, a skeleton filing. With regards to past BK, you will have the opportunity to incorporate anything that might be relevant and no, you do not want to reopen or anything. File anew. Chapter 13 is wage earner plan. You can convert either chapter rather easily. The only reason to avoid it is if you have already re-established credit that you don't want to lose.
(I might add more on the rest, but catching up at the moment.)
