OMG - How are you??? I'm sorry I have no info on Flagstar. I'm working several currently but they're the 'garden variety' BAC, Citi, Chase, WFB and GreenTree. You and I both discussed there are no silver bullets for these, just dogged determination which nobody appreciates or understands. I'll send you a private email of another source better for these kinds of questions.
All my best,
