(Re)starting REI journey: Acquisition Capital

[Jacob Mangalath]

I do not consider myself very experienced and would put myself just past the newbie stage.

Background:
I bought a couple of rental houses several years ago from a family member at very favorable pricing.  At that time I was told to pay off the debts as quickly as possible. I refinanced them both to 15-yr terms, that will be fully paid off in 2028 and 2031, respectively. 

Situation:
Upon stumbling upon BP recently, the aspiration of financial independence has been relit. Also, I believe there will be a fantastic buying opportunity in the near future. I'd like to get all my ducks in a row to be able to take advantage of this, so I'm preparing to set up an LLC (with a corresponding biz bank account) and moved saved cash there.

Question:
To get capital to acquire more rentals, should I:

a) move my current rentals as-is (no changes to equity/payment terms) into the LLC to use as collateral against future LOC's and Biz loans?
b) move my rentals into the LLC, refinance them to 30-yr terms (improving cashflow a bit) and at the same time cashing out a significant amount of equity, as capital to buy more properties
c) Leave rentals alone on current payment terms (not in LLC), and just use saved cash, LOC's and Biz loans to get capital to buy rentals?

I believe that based on my experience, I'm most comfortable buying and holding, also buying properties that don't need major rehabbing (although if it's in a good neighborhood - read great appreciation opportunity - I'm open to rehabbing). 

Thanks,
