Chris, you submitted a purchase deal where the ratified contract was within 90
days of the seller buying the property, which is eligible for FHA financing as long as certain criteria is met. Based on your post, i'm gathering that the transaction does not meet FHA temporary property flipping exemption criteria or the lender has overlays don't allow it. So the reason that the lender cannot move forward with the current appraisal is because the appaiser reviewed the original contract, and the date of the contract is shown at the top of page 1 on the appraisal. Logging the appraisal only verifies the information contained in the appraisal report, Asking the lender to order a new appraisal because you want to circumvent FHA or lender guidelines is called mortgage fraud. The case number has been issued and is associated with this property and will be valid for 120 day (if memory serves me correctly).
If the transaction meets the property flipping waiver requirements outlined in 24 CFR 203.37a(b)(2), find a lender that follows those guidelines and have the appraisal transferred.
