Appraiser - 60 hours just to become a trainee.  

It's scummy because they profess to want to deconstruct the house for the good of their trainees and the environment, and it turns out that those aren't the primary reasons.

I also passed the US-PAP Appraisal Exam in NYC, but have not done my 2000 hour "trainee" portion as of yet {I was an appraiser in California - no reciprocity w/NYC - coastal rivals :(}. 

As a real estate appraiser trainee, I have some tools that give some interesting insight on any user defined boundaries and time frame that includes price trends, etc.

To protect my time and financial interests -which are significant - the contract specified that the trainee does not have a right to terminate the agreement early and I can only terminate them for breach of agreement obligation or criminal/unethical actions.

I would think a new wholesaler would be best served by either working with another wholesaler as a trainee or bird dog  or doing some buy and hold deals of their own first.  

I would steer clear of any arrangement where the mentor/trainer has tens or hundreds of trainees.  

I get most of these lines of inquiry from this forum, and the trainees in our office.  

The trainer will use the trainee to simply bird dog for them and then take the deal themselves.

Each trainee's initial sales split the commission between the broker and the new agent to compensate the broker for his efforts to train the newbies.
