More data in the report, if given the proper amount of weight (including none) is not bad. Appraisals must be sufficient to enable the intended users to understand the appraisal. The intended user generally isn’t an appraiser, and they’re not an expert in quantitative comparison in every market they review. Sometimes they just need to see something analyzed that's overall superior to get comfortable. Sometimes in an ROV you throw the borrower’s sales on the grid to show them, despite these not being among the most similar sales, they don’t help your cause just because they have a higher price. Sometime when you have a pushy agent who knows the value isn’t there, you get their sales up front so you can analyze them in the report to pre-empt an ROV. This is the real world appraisers deal with every day. As long as it’s given proper weight, I really don’t see the issue.
