All those details would normally be reported in the listing history section. My take is that the opinion of value was, say, $150,000, the adjusted and unadjusted sale prices ranged from, say, $125,000 to $175,000, and the contract price was, say, $100,000. Now, the underwriter wants the contract price bracketed by something. In this case, my report was simply indicate that analysis of market data does not support the contract price as representative of the subject's current market value. If the deal was something like parents to son or similar, I would note that as well, but I would not waste any time trying to explain the difference between the contract price and my opinion of value. I have never seen any requirements to do so, save for in a few AMC engagement letters. Those I generally decline.
