I plan to do cost seg study and get bonus depreciation (and will actively participate as per IRS rules) but need to confirm if this would still work if buy STR under LLC and I can still be eligible for that STR loophole?

Of course this does not work as does not count the remodeling added value which is the simple success key.That is good also for investors you could advice: I would plan a joint venture with them participating to the profit on a certain % (instead of asking a fee upfront), so you would remain with a % of a stable return, while your investor could finance back the money from the property and start over again.

Aware of any networking events/groups I should try to participate in?

It seems like a really cool opportunity, so we'd love to participate.

Participate in discussion boards, post queries, and establish connections with other investors who might know more about the Pinellas County real estate market.Remember, every successful investor started as a beginner.

I attribute this to a lack of understanding of litigation, the claim participants and objectives of the parties (particularly the plaintiff's attorney and insurance carriers). 

If there is a REIA or meetup not too far, definitely join but be cautious until you get a solid sense of the agendas, knowledge and honesty of the participants.
