We are in a classic oversupply situation and there is a race to the bottom regarding fees that will only end when enough appraisers are driven out of the business to put the supply and demand of appraisers back into equilibrium. Its a very ugly situation and there is not a damned thing that can be done about it. It is not all that much different from the housing market in a lot of areas.
Competing on price is a lost cause since there is always someone willing to work for less. The only hope for a good appraiser is to compete on the basis of quality work product and superior service and hope that you can find clients that actually care about these things.
