Chad, you walked into a trap. An appraiser can form an AMC and thus compete as an AMC and an appraiser, but that would entail great expense. And a small AMC struggles to successfully compete against large national foot print/connected politically AMC's.
The individual appraisers who work for an AMC are approved by the lender client. And there are cases where a lender uses both an AMC and a panel. But limting the discussion to lenders using an AMC, here is what it looks like :
Appraiser Chad is approved by lender X.
Lender X can accept an appraisal directly from appraiser Chad. It cost the lender nothing, since the appraisal fee is covered by the borrower
Lender X decides to switch to AMC called Zipfast. You sign up for the Zipfast panel. Now Zipfast offers your appraisal service to the lender, AND the review and admin service of Zipfast - at no additional cost to the lender, because your appraisal AND the Zipfast "payment" (their profit) is divided from the borrower covered fee ( the split ). In other words, when you worked directly for the lender, you made $600 from the $600 borroer covered fee. Today, when you accepted an order from that same lender through Zipfast, you made $300 from the borrower's covered fee, and Zipfast kept $300. It costs the lender nothing to get both you and the Zipfast service. (Even if the lender technically paid Zipfast, it did not cost the lender )
How can you compete with that? With extreme difficulty.
If the lender had to pay a separate hard cost to use Zipfast , then you could compete on a level playing field. If it costs the lender $100 additional per order to use the Zipfast AMC, the lender might decide to use you instead and do their own admin. This explains why the lenders and the AMC's fight tooth and nail to keep the fee split system because it offers the AMC's an unheard-of, unfair competitive advantage in other businesses. Every other professional service or business has to charge a cost to its customers.
