There seem to be quite a few generalizations in this thread, concerning what happens after a BK drops off your CRs. Some say "scores go up!" and some say "scores go down!" post BK drop-off. The thing is...it simply depends on how you've managed your credit before and since the BK, with regard to accounts that will remain on the credit report after the BK and related IIBs drop off.
If you've had sterling credit aside from the BK, and rebuilt properly and quickly post-BK, your score will most likely go up...simply because you'll compare favorably to other's when you're rebucketed out of the BK grouping.
If you have some CR negative factors showing....late pmts, repos, collections, settlements, charge offs, liens, judgments, high revolving debt, etc...since your BK, then your score may very well go down when your BK drops off and you're rebucketed into a non-BK comparison group. They may have better CRs than you, so you're going to be penalized for it. Heck, it may even stay about the same for either case, depending on your credit history and reports.
It is VERY MUCH a YMMV situation...and aside from the above scenarios, perhaps we can avoid generalizations and hopefully stop confusing the less-informed readers out there.
If you've done your best and your CR reflects that accurately, then you'll score as well as you can...up or down, regardless of the BK, eh? Good luck!
