But it's a structured format so that commentary will always be in the same field in every report, not buried in the middle of another paragraph somewhere back in the addenda.
I've been using an Excel-based form format for most of my assignments since about 2007 or so. It's somewhat a mashup between TAFs Uniform Commercial/Industrial Appraisal Report format they published in the 1990s, one of the commercial forms out of the old MCS appraisalware program with a couple touches I added from the newer AI forms. So I'm only saying what I mean in my report; I don't have to deal with I don't mean so I don't have to add a lot of clarifications or redundancy. (I can use these formats because I operate outside the GSE pipelines). I did up URAR and 1025 versions in Excel but they're obviously not compatible with the electronic data transfer protocols the GSEs are using.
I use variations of the same format for all property types I appraise, including commercial/industrial, multi-family and land. The front and back ends are basically the same but the valuation sections are different. The SFR version I use runs 13 pages with the addenda of the report being limited to the pics and maps and such.
I run these on letter sized and with a default line height of .21" instead of the .18" that I have to use for the GSE forms I have. Fewer lines per page, less clutter, more narrative, more symmetry in my columns, etc. As a result, I never have to use an addenda with this type of format because I can put everything I need to say directly into the main body of the report. My readers read these from front to back so there's no need to refer further to an add-on in the back of the report. If my appraisal problem gets so hairy that I need more room to address a topic I simply add a page in that section of the main body of the report.
My point is that I don't save any time on my end when compared to filling out a URAR+addenda. What does happen is that it's easier for my readers to read, and easier for any reviewers to review because they don't have to looking for where I addressed something. Site issues are always addressed in the site section of the report. Improvements issues are always addressed on that page. etc. etc.
