The original post mentioned Passaic County - but rent control will vary per municipality. 

I don't even want to circle back with the lawyer I originally engaged as I was not impressed with his support or follow up.  

Origination fee was about 7K, about 1.5-2 points, and a transfer fee since the loan was being moved from one name to an LLC.

The original mortgage was 144,000 and I heard that the junior mortgage falls off [it was a tiny 32K].

You do not need a separate LLC for each property or a series LLC!

At a high level based on what I'm reading, this may be one of those where you give your brother an ultimatum: work together as originally discussed, or you buy him out and call it a day.

Florida was one of the original 13 colonies9.
