AMCs have contracts with major/minor lenders for the services. For example, a company like LSI is going to charge $375 for the appraisal to the lender (example - it's in that ball park but not necessarily that number). Out of that, they have to pay for their overhead, review services, ordering services, etc, and still make a profit. As we all know, about 50% of our fee is overhead. The AMC pays what they think they can get the work for and still make a profit. As a result, AMCs pay $125-$210 for what an appraiser would get $375-$450 directly from a lender. The same applies to BPOs. BPO from a lender would probably pay $100, broker gets $25-$45.
That's the nature of the market, and it looks like it's gonna get worse.
