WTF is wrong with you to suggest that fee dictates professionalism? you have no respect for your profession? those who have access to thousands of appraisals by thousands of appraisers have posted there is no discernible difference in quality between AMC and non-AMC appraisals and there was a study published that showed the same thing and/or minimal differences at best. you sure have a bad outlook on our profession, and since you attest to it happening you must be one of those who subscribe to that mentality. where else would you have any basis for proof of that? i have yet to see any study/concrete evidence supporting your position, but if you have some by all means post it so we can all be enlightened.
i personally put in the same effort if i am doing a $400 report or a $700 report or a report for client A or client B. i don't know why you assume something that is inherently untrue - i have never defended any AMC for hiring based upon the fee paid and have done quite the opposite, and i have never commented on AMCs engaging incompetent appraisers, but if that is your takeaway then that is all that needs to be said.
it's just like the C&R zombies who scream about it all the time and how unfair it is. it's pretty simple - i set C&R for my company, no one else. i set the level of professionalism used in my reports, no one else and certainly not the fee paid.
