Like many investors, I've reached critical mass (50 doors) with what I can manage myself (plus one girl PM help).  

I have done a few things, I have rentals, I have driven for dollars, I have sent out marketing, I have knocked on a few doors, and I have flipped houses. 

It also makes it harder for other operators down the road--- not your main concern but we all impact each other.What about you and your wife live in the garage unit, and rent out the house for a lot more, at least until all this permitting is figured out.

I could send you a handful of articles that would give you the basics and you'd be fine.I have 14-doors in Detroit and 3 of them I've placed S8 tenants in.

I own 4 doors and looking to continue to add more

I should have left at that - I listened to too many people to acquire more doors and it will "cash flow".  

Being the owner or investor behind the door of a NPN does not give you license to originate new loans.

I wouldn’t be surprised if it’s  a marketing gimmick to get potential borrowers through the door through  weirdly worded non recourse language that is effectively recourse or by offering such terrible leverage borrowers would rather have the recourse and competitive terms. 

But that’s going to be toilets, faucets, leaks, garage doors, etc etc. 

We had two others installed later to divert water from coming downslope into our yard to protect a drain in front of the garage.
