I have been consuming as much education/reading regarding out of state investing as I can as well as literature regarding buying larger buildings (not quite the syndication level) although I have been reading that material as well to digest.

Because later on, if you want to get a business line of credit, apply for grants, or pivot into a different industry (like buying an ice cream truck—hey, life happens), you can use the same LLC without lenders or banks assuming you're only doing risky real estate deals.
