I did a 5 minute research project. I looked at a comparable rent schedule, and I looked thru my USPAP book.
Let me start by saying, I was never advocating that it is OK for the rent schedule or anything else to be misleading.
Someone has had problems with the (North Carolina?) board, and the board has found the appriaser guilty of producing a report that "might be misleading to a third party". My comment: This is an impossible standard, because it could be true of any appraisal report. I do not know the specifics of this particular case. I use it as an example that not everyone agrees with my take on "misleading".
USPAP says that an appraiser must not communicate assignment results in a misleading manner. Comment: this is much different than saying nothing in the report can be misleading.
Assignment results is defined in the USPAP book. It clearly includes the appraised value, it may include more. The book says it includes "opinions or conclusions developed in the appraisal assignement". Comment: this is grey, could be interpreted to mean everything in the report, my take is that opinion of value is most important, everything else is less important.
Appraisal is defined as an opinion of value. It follows that the appraisal assignment is the body of work in developing an opinion of value. USPAP defiines assignment as a valuation service.
To the extent that the comparable rent schedule is related to the "opinion of value", it is part of the appraisal, and covered by USPAP. To the extent that the comparable rent schedule is related to the borrowers credit score (ie, not part of the opinion of value), it is not part of the appraisal, therefore not part of the assignement results, therefore USPAP does not apply.
