Chalet is a great resource for getting set up with a STR team.

As for the legalities of setting up an LLC to protect you and your partners, I would consult with an attorney for best judgement. 

The property owner can give those to the appraiser also so he can put it in his data.

For active investing it is also helpful to have some type of advantage that sets you apart from other investors - that could be construction or rehab skills, market knowledge or anything else that gives you an edge.I was an active investor and didn't really have any of those skills.  

This property offers spacious townhouse like setting floor plans offering one, two and three-bedrooms.

You can set it up yourself at www.sunbiz.org , which is the website for the State of FL Division of Corporations.

I own a LTR in central Houston that I think would be pretty successful as an STR based on the AirDNA data.

Some investors will wait until they have several properties before forming an LLC but it's often beneficial to set one up early especially with your first property.

Even with 200 STRs it isn't a broad enough cross section to assume the changes.You would need to have millions of data points to show the trend IMHO.
