From what little has been leaked, 12-18 months is the pace. But the fall out rate is ridiculous, again from what has leaked around 90% haven’t completed the course.
I see you’re in MS, a better bet is Melissa Bond and MPAT. I’m not a a fan but to her credit she has graduated more students than the Appraisal Institute’s PAREA. But you will have to apply, and if you don’t fit the mold of who she thinks is a good fit to be an appraiser then you’re out of luck. Not much different than finding a mentor, although they don’t want to admit it.
Either way a bit of advice, and remember I’m not trying to sell you a class. Certified residential appraisers are dropping like flies, even through the absolute crazy busy pandemic time period. And neither program will get you to certified, and what they won’t tell you is licensed will severely limit your ability to land the work that Ms. Bond and the Appraisal Institute say they are training you for. So you will probably be someone’s de facto trainee for many years until you become certified, so don’t buy the dream they are selling, you have years of hard work and low pay ahead of you. Go into this with your eyes open and make the best decision for you and your family. Good luck.
