Proforma problems? Are they even useful?

[Douglas B.]

It seems like a proforma is only of limited usefulness because it can be so wildly inaccurate. How do you pros workaround the sellers lies and misrepresentation on a proforma? What tips do you have to help a newbie prepare to interpret proformas when I start looking to buy in a few months? What do you do when your seller isn't forthcoming with the financials, receipts, tax documents, etc. Do you just move to the next property?
