Get the right team and you will only have to worry about paying bills and collecting cash flow.   

In terms of my goals, I concentrate/focus on three metrics (and cash flow isn't one of them because that can be manipulated). 

I plan on getting a property every year until I retire if I can find a good deal that cash flows positively.I have a very close friend whose stationed in Columbus GA whose a real estate investor and owns rentals there!

They also stated they only allow three brokers and three cash homebuyer “spots” in any given area, and they only move into areas where they can guarantee at least 600 leads per year.

Socal is tough to find investment properties that work.I have a great realtor in Sacramento that can find properties that cash flow.

They require all cash to buy so the people there have money.

Would a cash out refi be under commercial terms since the property(s) are under LLC?

Sounds like a cash out refinance would be the best way to tap into that equity. 

They have been the best investments I've ever made, but hoping to have greater cash flow influence with a daily business model.Is there demand for these types of rentals in the investment community?

You do have to purchase at least as much real estate as your net sale if you want to defer all tax.TICS are generally cash deals.
