-The state just passed a law this year that no municipality can regulate fees or charges for rental properties-The state passed a law that any type of rent control in the state is not allowed.

And you are right most money manager types won't advise you to hold RE because that is out of their control and they cannot collect fees under management. 

If I install some smart lock door that I can control entry code, then I can simply give the temp entry code to the applicant.

I remember a time back the folks at Bigger Pockets were promoting Josh Cantwell, Appearantly the guy has salesmanship but look up the details of what he offers and you will find he wants the best deals, a sure profit and at minimum 16% on his money, plus he gets you to do all of the leg work and contruction but he gets to select the deals and control all of the money. heheheh When Josh was just a young lad he was told that, "there is a sucker born every minute" then instructed to go out into the world and find them.
