Working in Real Estate, I'm currently dealing with a distinctly frustrating lender issue. The other agent (we represent the sellers) has been great. Also, the lender's mortgage staff have been great and responsive. But we have an appraiser who the descriptor "slow" is a glorious understatement. So, a few points of frustration on this. One is obvious: everything is backed up due to the sluggish progress of one individual. However, the bigger point of aggravation comes from this appraiser's routine failure to produce documentation in a timely manner. Being on-time is the rarity, as confirmed a few discussions.
It's easy to be frustrated with the appraiser, however, that's not entirely fair. When routine incompetence isn't addressed, that's a management failure. I understand that banks and appraisers need to maintain an "arms-length" relationship. However, a documented pattern of failure shouldn't, well, can't be tolerated. It is terrible customer service, and reflects poorly on the whole institution to the other stakeholders.
It's bad enough to accept mediocrity. Accepting incompetence? No, don't do it. Don't!
