Thanks Granny031350 for your response! By the way, this is the very first time I have ever posted a comment or question on any blog!
Having spent some time recently navigating through this credit labyrinth, I have come to understand that FICO scores are one thing, and then the ability to obtain conventional Real Estate loans, though related, quite another. For instance, FNMA's recently published Announcement 08-16 sets forth the time periods one must "wait" to "re-establish credit", regardless of FICO scores, after BK, Foreclosure, short sale, etc. For BKCH7(first time), it states 4 years from either discharge or dismissal. So I guess my "modified question" is: If I file, and subsequently the need for bk protection is eliminated through, say, a windfall, is there a way to rescind the filing, or are the only possible outcomes dismissal or discharge? The answer may seem obvious, but maybe somebody out there knows of some (obscure) exception.
