IF it is managed well and in an area that has demand, the AirBnB model should generate more money.

Most expensive things would be A/C unit and furnace if they weren't operational.The reason for buying this house is so that I could focus more on generating my passive income without the strain of having to work a 9-5 while also running my business.

Now that I am an investor the first things I look for are the electrical, no knob and tube or the generation after that, I look for problematic asbestos, and I look for indicators of structural issues whether that be foundation issues or things like doors not closing, sloping floors and lots of cracking walls.

Leasing was not generating wealth.

You have a lot of pieces here...but yes you pay State income tax on the income generated in that State.

Here are some important things to consider:- I am pretty much at capacity running my RE business, so I don't have a ton of bandwidth to do it all myself- Let's presume my opportunity cost is such that pulling away from my RE business to "do it all myself" for these rentals is not a good use of my time, as I'd earn a higher dollar per hour being the CEO of my RE business than the dollars per hour savings trying find off market deals (I.e. saving 20k and trying to do the rentals myself would cost me more than 20k of lost opportunity cost by pulling my attention away from CEO level tasks at my RE business, which might generate 40k of revenue for the same time)- By the same light, turnkey could be an option, I'd be willing to pay the turnkey premium for the time savings of finding and vetting my own deal, however I know I'd still need to underwrite my own deal provided by a TK company, so having someone who can help that underwriting process would be super valuable, rather than me trying to learn from scratch how to properly underwrite the deal.

I wouldn't do random searches on zillow, trulia, or redfin as 95% of agents have zero experience with investing and won't be able to help you.The agent can recommend others they have worked with and why they work with them.  

However as I still do work a day job, I an not quite at the point where I can start taking Random Phone calls from the general public, which makes Driving for Dollars, and mail campaigns challenging to field leads (Phone Calls) in the middle of the work day.This is where I need to start playing to my strengths. 

Not that it matters in the grand scheme of things, but Florida's no income tax will seem like less of a consolation when you see all the random BS taxes that show up on your property closing statement ;)

Once you determine your market, its a matter of generating a list of properties and marketing to them in a variety of ways.
