At least you are trying to do a good job. As a new employee, you can't rock the boat and make immediate radical changes. To answer your questiosn, yes, send reports back for additional commentary or to address deficiencies.
I dontt know what fees are being paid by the AMC's this lender uses, or what is charged to borrower. It is not always a matter of increasing costs to borrower, rather, how much does each AMC skim off the fee. Maybe choose AMC's that are taking 20% of the fee as opposed to 40%, for example.
I think a first step is auditing the process by which these AMC;s assign work. Lenders as you know are going to be under more scrutiny for their due diligence in appraisr selection. They can't just throw up thei rhands and say they entrusted the AMC to do it.
First of all, ask, specifically, of each AMC, if they are assigning work to Forsythe and Metro West appraisal firms. These are national appraisal mill firms (check them out yourself), that hire fee appraisers as "staff", with extreme low fee splits. They take on bulk AMC work at low fees and then pay an even lower split to their "Staff" appraisers, who make around $125-$140 a report. In order to accommodate such a low basement fee, these appraisers produce bare bones generic research and canned commentary reports. So that is the first proactive step you can take. You might want to prohibit outsourcing appraisals to threes firms, if that is what is going on.
The other thing you can initiate is a yearly audit of all AMC's now doing this ordering. They have to submit a breakdown each year to you of which appraisers are getting the assignments in each region, and how much experience they have, and then compare that to the names on their panel and how much experience the appraisers have who are not getting work.
It also comes down of course as well to individual appraisers. Flag the names of those who have a pattern of submitting low quality /questionable reports, your company call tell the AMC they prefer not to receive reports from that appraiser.
( as an appraiser, though I dislike generic commentary, what is of more concern is if these appraisers are fudging market conditions to simplify analysis and thus saving time in reporting ....are these reports showing very market stable and supply and demand in balance, for example. (when they might in reality be declining or over supply or rising etc)?
If budge allows, forward a few of the most questionable reports for full field reviews (
