the link i posted suggested two things. that loans to the self employed are more laborious for the loan borker and that documentation does include tax documents taken directly from the irs. so personal accounting may be out as the banks may not bother looking at your books.
other thoughts… maybe he *needs* the stated income loan in order to get the deal done in time? waiting for the irs to send the loan officer paperwork is too slow? whatever the case, he’ll probably be better off being denied at this point, that the loan guy is doing him a favor?
