You should spend time catching up on relevant mortgagee letters for the past 5 or 10 years, reading the handbooks which describe HUD minimum property requirements (existing improvements) and minimum property standards (proposed improvements), THOROUGHLY read and UNDERSTAND the revised Appendix D to the 4150.2 and work with an appraiser experienced with FHA assignments for the first dozen or so.
The VC sheets may have gone away and so did the test, but as a licensed or certified appraiser you will be held responsible for knowing and executing the proper scope of work.
Check for adequate drainage, fall distance of power lines/towers, the distance of wells to septic systems and property lines, the availability of public sewer and water connections for properties on well and septic, fireblocks in common attics, blah, blah, blah. The list is almost endless.
