Be willing to seek out opportunities that may pay a little less than you would hope if you will be gaining valuable experience.3) If you have a degree, consider management trainee programs.

Yeah,this is a messed up situation all around.She sold you to her trainee like a Thanksgiving Turkey for a huge slice of any potential commission which she is assuming will be few and far between,if any.You’re not a real investor to a veteran agent until you have pulled the trigger and made an agent some money,she didn’t want to deal with it.None of this should have happened the way you were treated and you should be filing a complaint with her broker of record to have this mess dealt with in a professional manner.

Work on both of them together (granted, making the trainee do more of their work to give them experience)? 

I came across a sign that read, "Real estate Investor seeks trainee, earn 5k/10k a month while training."

I was lucky enough to get a job as an appraiser trainee.

This morning while driving around I saw a sign on the side of the road, "RE Investor Seek Trainee. $1,000 - $10,000 2x wk pot." and then their phone number listed. 

Hey Joe - I know of an appraisal company in NYC that is currently hiring both licensed appraisers and trainees. 

I'd like to begin transitioning my business as an agent to use my license primarily for investors, rather than residential sales, while I work towards my appraisal license (if I can ever find an appraiser to take me as a trainee) while building financial freedom with a good personal property portfolio.

I am a former Appraiser "Trainee" stopped just short of getting my full license when the market crashed in '08.

Just had to add my two-cents here regarding @Alexander Felice's comments:1)  Seems like a strange place to voice housing discrimination against military- considering most people in this forum have honorably served their country.2)  The mostly young Air Borne soldiers of Fort Bragg vs pilot trainees in an 18 month program are two very different things.
