I'm sure I will get blasted, but why would the scope of work be so different from one mortgage lender to another.
For an FHA assignment, there should be similarity in many regards. The potential issue is those pesky requirements that exceed the 4150 that most lenders seem to have these days. If "Lender B" is identified as the client, then the appraiser takes on the responsibility of identifying, and complying with, any assignment conditions that might be imposed by "Lender B." Even if there are no additional assignment conditions, the appraiser is obligated to find that out, and that takes time.
I'm all for getting paid as much as I can, but I just don't feel right about charging the borrower for a second appraisal when at the end of the day all that is being done is cloning the same report.
The lender has the option of using the original report. If they choose not to do that, why should the appraiser be required to cover the cost associated with that choice?
The lender is the client, and the lender is typically the one being charged. If the lender chooses to pass the cost along to the borrower, that is a business issue for the lender, not me as the appraiser. I feel for borrowers too, but no so much that I will work for free. My company and my family count on revenue from the work I do.
Even if the appraiser decides the original SOW is basically sufficient, time is required to produce a new report, and there is cost associated with creating, delivering and storing a new report. The appraiser is also exposed to the liability of an additional assignment. All of those things clearly warrant additional fee.
One of the biggest issues appraisers face right now is that too many of us do not make sound business decisions. For years many lenders have beat appraisers into submission with regard to fees. That is why so many appraisers are pursuing non-lender work as their primary base of business.
