re: OP bad grammar... it is clear from the post that his/her mentor has their hands full re-writing OP's appraisal commentary, assuming the mentor puts out a good final product. Doesn't matter whether English is primary or secondary language; no excuse for lousy quality of report. I've had 1 trainee with ESL issue, which required more of my time to clean up his reports, and another trainee whose verbose overly rambling commentary took more time to tame into readable language than if I had done the whole report from scratch; I couldn't afford the hours of correction/clarification per each appraisal and had to let her go. She didn't understand that every time you say something in a report, that opens the door to litigation, and so don't ever say anything that can't be corroborated, or isn't truthful, and don't speculate about things not germain to the issue at hand. If you open the door, worst case scenario, some legal eagle will walk you through it and you will not like where you find yourself.
That said, answering original question, despite having 20+ years as real estate broker, I was paid $30/appraisal, then $60, then $90 after more than a year, and after obtaining my Certified Residential Appraiser License, I was paid $150 each... but that was after more than 2 years in. Appraisal fees at that time (18 years ago) were about $25 less than fees today. Now THAT's depressing!
