Reducing fees is easy. Raising them back up is hard. Once you reduce your fee, that new lower amount will become the new standard for a while. It's a dry season (has been for over 2 years now). Live cheap and weather the storm until volume picks up again. I try to increase fees every other year. The clients have all been supportive of my fees and I have not lost out on work. Most of my clients rotate, so as long as you are not outrageous, you will get the work.
Ask yourself if the lower fees will trigger enough volume to offset. Seems to me, we would get a larger volume, but at a reduced fee. It likely ends up a net zero sum gain, or close to that. I would not anticipate appraisers would see a significant increase in volume during a dry season even with a slightly lowered fee. A 10% increase in volume is probable. A 25% increase is not likely.
Math illustration:
If I anticipate doing 100 appraisals in the next year at $400, I would gross $40,000. (Just keeping the math simple and using the fee quotes already mentioned in this thread)
If I lower fees to $375 and get a 10% bump in volume, I would gross $41,250 (110 appraisals x $375).
The difference being a positive $1,250 for the year. On average each appraisal takes 8-10 hours of work, at least for me (taking the order, research of property and set up of file, travel to and from property, inspection of property, write up, travel to take comp photos, proof read). And do not forget we also take time to do bookkeeping, IT and other maintenance for our office files.
It is reasonable to conclude 10 hours per appraisal.
Additional 10 appraisals for the year x 10 hours = 100 additional hours for the increase in volume.
$1,250 / 100 hours = $12.50 / hour.
Not worth my time. I would rather have the time off.
