Over the year's, I have had appraiser's call out items during their appraisal, that they wanted either verified or explained away by me, on letterhead. In all cases, it was a total waste of time, and simply the appraiser, not knowing what they are looking at. For example; I had an appraiser call out a Zinsco panel on a 2000 built home. They required that I put on letterhead, that it wasn't. That letter was a bit snarky to say the least.
