FHA Appraisal came in $40k low, what should we do?

[Kris Haskins]

We have a house that comps at $200k, and have a 3 month old appraisal that backs that price up. Our buyer just had an FHA appraisal that came in at $160k. We've tried to give the comps from the $200k appraisal to the new appraiser and he's only adjusting up another $5k. Can somebody please tell me how to handle these guys and perhaps get a value to the lender?
