I have purchased 3 STRs personally in the last 18 months and have closed on at least 25 for clients in the past 12 months.  

Assuming I also use the Airstream for lodging while traveling for personal reasons, would I just take a pro-rated amount of depreciation for the amount of use that is business vs. personal?

People like to rent from a person not a 'brand', it's more personal.

Home insurance would cover anything on premise, but as @Jonathan Bock stated, it's usually for significant damage.This might be something you would tackle on your own, but worth to have a conversation with your provider first to see what they have to say.

I've heard good things, but not personally worked with them. 

Market timing, properly acquired property, personal capital available How did you find this deal and how did you negotiate it?

I am personally working with about 15.

I'm a licensed sales person in the state of Florida (located closer to central FL, Space Coast area if you are familiar), with intent to enter the commercial real estate brokerage industry as soon as I can find footing.

I think I can open another personal checking account at the bank I already have and it'll be under my name but i'm trying to buy out of state rentals with an LLC I own.

NOTE: an aggressive attorney can still track you down.LEGAL PROTECTION: By placing your assets in an LLC, you legally separate them from your personal assets.
