Dave,
The first thing is that we don't use screen names on this forum, we use our real names. That's a rule here. It helps keep us honest. When someone says something totally outrageous on this forum (not that you have done that here), the first thing I do is check to see if they are even a licensed or certified appraiser by looking for them on the Appraisal Subcommitee's website. It is amazing how many of the really obnoxious posts on this forum have come from non-appraisers and wanna-be types.
And now, to your question. There are lots of tip and tricks to learn in order to be a better appraiser. Too many to list here. And this is the first tip I'm going to give you:
The one thing about working as a new appraiser is that you will naturally tend to pick up your supervisor's strengths as well as any weaknesses they may (or may not) have. The way to find out where your performance stands in relation to other appraisers as a group is to follow the different forums here. I'm sure I'm not not alone is telling you that I wish such a resource had been available when I was starting out.
Another tip is to take as many courses as you can and pay attention in class. Your main motivation for taking a course should not be to earn the education hours and the certificate, but to absorb the material. Basic, advanced, and continuing education requirements are not a prison sentence to be served, but an opportunity to become a better appraiser. This may sound trite, but your ability to work through a difficult assignment will almost always depend on your knowledge and ability to apply fundamental appraisal theories to the problem. You won't be able to do that as well if your training and orientation is centered around how to properly fill out a form or follow lender guidelines.
The last thing I'd like to point out is that appraisal ethics, USPAP and the laws and regulations that govern your appraisal license are not a joke. You should take them very seriously, even if others around you don't.
Assuming you have the necessary self-discipline, motivation and a modicum of intelligence to work with, if you do these things (read the forums, learn the material, follow the laws), you'll succeed.
Best of luck,
George Hatch
