So, the appraiser has to waste time seeing what the actual property is to value, which is not always that easy to do. Log in, pull up a tax card or MLS sheet... estimate what the fee should be based upon your best guess as to the time spent... Submit to AMC, who then does not respond because they are scrambling to find someone else to do it cheaper... and then what? You've wasted a hour of your time doing nothing, and knowing by submitting any other bid, you probably are going to not get the job and B - if you take 3 days to do it, on day 2 they suddenly cancel the job by which time you've got it half done and they are not going to pay anything, not even a trip fee. Great.
