I think this is a timely discussion.
We have found that the only time an agent wants to be present is when they are concerned about the appraiser hitting the sales price. And then they want to be present to influence the appraisal, with some being more subtle than others.
Unfortunately, it can be difficult to hit the right "tone" when you need to tell an agent (or homeowner) to back off.
I have been considering writing a general blurb to send via email, a basic Do and Don't list, or something like that, but can't figure out how to word it so as to not kick that hornet's nest unnecessarily. Was hoping the forum could collaborate on that.
Just last night/this morning I had a seller/flipper email to request a meeting prior to the appraisal to make sure the appraiser knew what to pay attention to when valuing the home. Then he called early this morning to push a little more. When my calm words asking him to be mindful of appraiser influence regulations didn't dissuade him, he sent another email with his expected valuation. I contacted the lender, a very good client, and asked for the assignment to go to someone else. I feel bad for the client, and the house looks like a stunner on the MLS, but when a party to the transaction is really wound up from the get-go, it's usually downhill from there.
