I tried google/youtube searching and not finding a lot of info.

But if you're going the other way you could always fill the house with snakes and/or rats.This would make for an interesting skit for your youtube channel. 

I think The Short Term Shop has a video series specifically on STR Legislation in Branson on Youtube as well.

Attorneys (want your money), YouTube gurus (want your eyes), and amateurs (don't know any better) will all insist you set up an LLC for asset protection.The truth is, you don't need it.

Also, if you know anywhere, book or video where I can learn to do due diligence and the other things you mentioned, please let me know.
