This is directed to anyone claiming USPAP is too long and complicated to follow.
USPAP is a very simple and easy to follow document.
As a certified appraiser, all of your reports certify that you have read and follow USPAP.
Every two years you take a USPAP update course.
I'm sure, in a profession that requires you to follow the standards you certify to follow, you can find time to understand the content from the Definitions through Standard 2, its only 24 pages.
It took me 15 minutes to read these sections and type the following summary. You have time to read USPAP and follow it.
Definitions: just read them
Ethics rule: don't be an a**hole, be independent, don't be a liar, don't take bribes, be confidential
Record keeping: make a workfile and keep it for at least 5 years plus 2 after disposition
Competency: be competent, acquire it, or withdraw
Scope of work: what does the client want, what steps can you take to meet their needs, report what you did
Jurisdictional exception: follow State Rules and disclose it in the report
