Yes, the basic form is the same, but how the various software vendors, and various appraisers, format (or do not format) text addendum pages makes reading many appraisal reports akin to a giant Easter egg hunt.
In most forms software, if the comments in a section will not fit on the form, then the software automatically creates a text addendum page. But how that addendum page is presented varies. Some software organizes comments so that the items appear in the same order they appear in the form. Some software puts the comments in the order that they are typed. And, some appraisers do not use the auto text addendum feature and create their own, often without labels, and often covering the same topic in multiple locations. The most difficult to read are those with the "walls of text" (love that description that someone else used) with not a single line break or section header.
I have seen reports with the "prior services" comment in three different places in the same report. And, in some of those reports the comments contradict each other. (e.g. page 3 of the URAR says no prior services, but a blurb on page 15 in a text addendum says the appraiser did provide prior services).
I 100% agree that reviewers should read the report. But, I also think that many who write those reports could do a better job of making them easier to read.
