This lender is giving them a meeting, which in most cases you are just done without a notice. So how bad is the lender.
The question is, is this just 1 appraisal complaint, or your overall work. Did they give you specifics, or is it gonna be a vague bear trap to put your foot into. How do you defend yourself with any vague questions. Be careful how you answer, or maybe don't answer a vague question, but you seem to have things covered. You may come out innocent, but still lose the client. They may have more easy appraisers to do their deals, so i don't understand the meeting part purpose. Maybe they like you, but want you to be a kinder appraiser. This is a good post for use here to learn something when you get back from that meeting. We don't get to many, or none, of these issues posted, or completed.
Of course, i have direct lenders for a long time, with whom i am friendly. I can call someone higher up and talk about anything. I had to only do that once, but it worked. My big lender has a compliance attorney on staff.
