How will I now the right mentor is a good fit for me and l for her/him?

A good feel/fit for the broker and trainer is important, however, don't look to be too warm and fuzzy--you need to find someone that can teach you, challenge you, help keep you motivated and goal oriented. 

Look for a place that does 1st time homebuyers programs.

I use Turbo Tax and the program just asked me if my SFH properties are Qualified Business Income or not. 

The odds of you finding the scarce lender that has some amazing program others do not in the market is very small.It happens occasionally but only a small fraction of the time.

On a smaller scale, just call a local broker (better: call all top players, hopefully there are 3-5) and tell them you have 7 properties that you want to place in their rental program, and want details on how their rental management operation works.

Some might fit your needs better than others, but there are definitely options.   

Deals would go dead, delays would happen, and agents and loan officers simply would raise a fit if that ever happened.

@Austin Hendrickson no plans of being in Minnesota anytime soon mostly due to our offseason program starting but would love to connect over the phone sometime soon!

I also qualified for a down payment assistance program.
