I won't be able to invest for another 5-7 years since my wife and I are working on paying off debt and saving up for a down payment on our own home here in Florida, but real estate really interests me so I am trying to learn as much as I can so that when we do decide to dive into it, hopefully there will be several things that I have a decent base in.

I'm not sure about your market, but the housing authority sets the rent based on comps submitted here in Atlanta. 

Of course not.If you consider the fact that if you have no money, you would be better off going to McDonald's, getting a job, working for 4 months saving up a decent marketing budget, and THEN attempting wholesaling, your chances of success FAR supersede the chances of doing what is cheap (but with a terrible success rate).People, understand this.You do not seek success based on what you have.You need to figure out WHAT YOU NEED to become successful and get it.

I based out of Houston, TX and been doing title research mostly using the county clerk site.

The opposite also holds true.As a REI, trying to judge if an area is a good area to buy as a rental, is and always will be based on the ability to CF. 

Lastly ,  Based on my experience . if you are hitting up 100 pips and maybe contacting 50 or 30 , maybe the approach and sales skills might need to be tune out..     

I heard that the greater than 1 year holding is based on how long my parents held it, not based on how long I held it.

If the base zoning is RSA5, single family is the allowed use & lot area is not relevant. 

Setting up a US based entity is your first step, you are already doing that it seems. 

Ideally you have some sort of base to work with.
