How would you approach the problem? 

I can't see the investors who are looking to rent from landlords; I have never had an investor approach me regarding renting one of my rentals, on a quest to sublease my houses.  

I guess I’m just trying to figure out the best approach to grow a business that will allow me to retire in about 10 years.

Looking and hoping to receive some advice from more experienced individuals on here on how to approach other investors in regards to mentorship.

I’d just call/approach the guy with WTF are you trying here?

When I see new investors with healthy budgets ask these questions in an open forum I always envision a bunch of sharks circling him in the water.
