I would just lightly advise away from complicating your day-to-day life at this point given what you've told us. 

You just need to really make sure you understand and are cognizant of all the features of a floating rate loan - often times the structure can be complicated and you don't want to miss something, especially related to any "caps" - just make sure you are better safe than sorry

I think yes to the LLC but you can do that after you purchase. it makes things unnecessarily complicated IMO for the purchase process.

I have credit already established and want to make it less complicated.

Or you’re going to charge market rates making it worth nothing to the tenants except complications and the fear they are being ripped off. 

Section 8 can be great, but you have to know the regulations and complications of each area and how that locality processes the applications and tenants.

in terms of actual cash invested, it gets a little complicated.  

Obviously there's a multitude of complicated contributing factors, but I think higher density housing even in formerly lower density zoned areas via ADUs and Jr.

Seems like a very simple transaction but becomes complicated because we are in two different states.

@Erica Schubach I would say if you have a HOA, it all depends on their regulations, but from what i have seen most HOA in Kansas City area or the cities that are better areas like Lee's sunmit, overland park, they prohibit short term rentals, plus the rules of condo are much more complicated and more strict than single families or townhouses.
