This is basically what I do. I comment in my reconciliation that the adjusted sales of the comparables indicate the purchase price is supported...... and come in at the purchase price LOL. This has upset people for years. I have when it's glaringly obvious, opined at a higher value than the contract price.
What's more upsetting however, is when you reconcile below the purchase price and state that the most similar comparable sales to that of the subject, appear not to support the purchase price. Back in the mortgage broker days or with the AMC's..... doesn't matter, everyone's upset.
I always thought the appraised value should be a range of the adjusted sales, not an "exact" number and let the lender make the final decision. No one's that good...
