purchase with open Chapter 13 BK (IL)

Is it possible to do this type of transaction?  My clients want to purchase a single family, owner occupied in Illinois.  They received the trustee’s permission to buy but who will lend and under what circumstances.  FYI — there was (1) late to the trustee in 7/01 due to spouse being temporarily on medical leave.  BK was filed 4/00. I don’t have any other info than this; will begin processing only if loan is possible.
