These cash flow very well. 

You can indefinitely defer the tax and use it to purchase nicer property/properties, as well as not have to recapture any depreciation.

Well I have seen this come into play - I had someone who has a note in florida that was a non-owner occupied loan and the lender claims the borrower failed to make payments on this and attempted to record the deed in lieu.

It sounds like you navigated the challenges well and gained valuable lessons for your next venture.

I respectfully disagree with @Joshua Dorkin  as well.

I'll send you a DM as well. 

What types of IRS/CPA approved payments are working well for rents to LLC entities to keep personal and business funds from co-mingling? 

I am doing by the room as well and it has been a struggle to find a pm that will manage it! 

I often read that one should seek a commissioned sales role because your comp is uncapped and that has served me well. 

To simplify the scenario I'm envisioning let me put it this way: what does a BRRRR look like when one of the parties contributing to the down payment and rehab costs ultimately ends up being the renter as well?
