What is your strategy for your business vehicle?

Capital should and will move to highest risk adjusted rate of return vehicles. 

A lot of things happened while I lived in the back of vehicle that stalled my progress. 

But more importantly you need to speak with a wrongful death litigation team to find out how they dismantle LLCs in court.LLCs were never designed to be used by participants in commerce as asset protection vehicles. 

Ali,totally agree with you 100% TK offers lots of built in experience that you simply cannot get anywhere else let alone with any other type of investment vehicle.

If some scenario came up where you were being sued I don't think an attorney would have any difficulty proving that these are not separate entities.You may want to look into S-Corps, as I seem to recall that being the preferred investment vehicle for flippers.From what you're describing I don't think you're achieving any benefit and you're certainly incurring extra expenses and headaches by titling each property in separate LLCs.

The vehicle will be used 75-100% for business for the next 5+ years.

And you are also not correct, as I see some benefits of having an LLC:First of all, having personal vehicles and primary residence in an LLC is useless - unless you can prove doing business activities with them.

Interest rates should effect commercial more, as well as what other investment vehicles are returning.
