2-2b(viii) summarize the information analyzed, the appraisal methods and techniques employed, and the reasoning that supports the analyses, opinions, and conclusions; exclusion of the sales comparison approach, cost approach, or income approach must be explained;
Comment: A Summary Appraisal Report must include sufficient information to indicate that the appraiser complied with the requirements of STANDARD 1. The amount of detail required will vary with the significance of the information to the appraisal. The appraiser must provide sufficient information to enable the client and intended users to understand the rationale for the opinions and conclusions, including reconciliation of the data and approaches, in accordance with Standards Rule 1-6.
Therefore , the bank and Kevco is correct. If your not explaining then your not producing a credible report."
I agree.
A Summary analysis which may be acceptable to, and sufficient, for knowledgeable Lender/Clients is likely insufficient for "intended users" OR others who "may rely" upon an appraisal report.
Despite the USPAP identification of named "intended users", since the GSEs revised their form Certifications 21 and 23 AND Doof-Thunk 2010, anyone who may get his/her hands on an appraisal report, including typically unsophisticated parties (re appraisal terminology) considers themselves "intended users" - including borrowers who must receive a copy from the Lender.
IMO, the demand for "specific" support for each and every line item vs a summarized analysis is not required by the GSES or the USPAP in a Summary Report and represents an assignment condition which must be accepted and dealt with accordingly or an order must be declined.
