Does it really matter?
When I started as a trainee, I was told, we write in 3rd person because that's how academic papers are written and presented. Professional, Intellectual reports are not love letters, and should always be in 3rd person. That's what I was told.
But then the real world kicked in, and you start to ask yourself why you are writing on the equivalent of an academic study to some idiot that is asking you if any income producing activities were taking place in a 1400 sf ranch simply because the zoning allows for such, AND, you have provided them photographs, which you don't find in academic studies.
So after multiple comments similar to, I saw a bed and a computer, I did not see any income producing activity, but it was early in the day and I can not comment to what might be happening after the sun goes down, you give up.
Even with the giant mixed use retail/warehouse/apartment complex, "appraiser to state why they believe the residential leases are not valid", just because no apartment had any food or clothing or soap or toothbrush and the supposed leases where more than 3 months in, well, again, you just give up and write toward the lowest common denominator. After all, effective communication includes considerations for the understandings and reference points of your intended audience, so now, first person and very plainly written communications with all technical words defined and referenced and explained. Because it really is not about how well, or not, an appraiser can compose. It really only is about how well, or not, the reader understands, as that's all that really matters.
