IOW, are seller paid fees such as origination fees, appraisal, etc exclued from the Page 3 HUD Comparison chart is paid by the seller?
No. Every fee that is on the GFE must be shown on the HUD, no matter who ultimately pays it.
Further, fees that are on the GFE should show in the BUYER's column on the HUD, not the Seller's. You give a credit on p1 for items paid by the seller.
But first you need to verify that the pest inspection was a condition of getting the loan, not just something that was written into the offer. If you don't require the pest inspection, then it doesn't belong on the GFE at all (or on p3 of the HUD) and you can put it in the Seller's column.
