One of the mistakes many appraisers make is bidding an appraisal based on the job as a unit rather than the time and effort that might go into it.  Strangely, we are one of the few professions that look at our work that way.  Instead, we should judge what we do based on a per hour basis.  But, how do you properly bid a job to know you are well compensated before you even begin.  There is a proven trick we can utilize.
