So this program is between the property mgmt company and us, mostly. 

Not even Ivy League master programs in real estate provide the representations and guarantees these mentorship programs provide.  

If it's just a money grab and there is no desire to associate with the aforementioned, you will most likely be on the losing end and feel very negative about the program.

Quote from @Kyle Carter: What about if I already have a rental, not with the home buyers program.

Robin Carriger is the organizer and they usually post notifications here on BP.I've posted other lists here several times and can do so again if you need it and can't find in the search function. 

We rent to plenty of S8 applicants; I've always believed the standard of care they exude is as high if not higher than "market" applicants because they'll get kicked out of the program if they don't.

I will be switching to a new program.   

As I look to grow, I’m considering joining a coaching/mentorship program like Partner Driven or something similar.

What is the experience with this program - Pro/Cons, watch outs, etc?. 

It is a done for your type of program but they do teach you how to do it as well.
