All I can say is that when an investor is the person who's doing the job that a real estate broker is commissioned to do, per state law, that's brokering without a license, which is no bueno and shouldn't be allowed. 

You’re going to deduct the rental mortgage interest against your rental income and your personal mortgage interest (if allowed and more than standard deduction) against your regular income.

I personally own 2 rentals in Indiana.

You develop relationships with a handle of people that are creating notes and you help them recapitalize, it is like a conveyor belt of deals coming to you.  

I would be very careful with a lot of course or guru in general right especially a price tag like that what I would always recommend reading the contract and see who is the person more in favor and if its not you then dont sign up very rare to see someone actually benefit from a course.

The answer to this question is really a personal one. 

Do they have solid banking relationships and broker relationships to lease out the units. 

Renting part of the home after conversion provides additional income and deductions.This post does not create a CPA-Client relationship.

Really the person that is going into the flipping game should know the market very well to do these comps on their own, and back it up by asking their trusted real estate agent/professional for confirmation.
