Would cash out refinancing be an option to do there as in the BRRR method?

Even though the deed is passed directly from buyer to seller, the usual method is for the contract to be assigned to the QI so the QI as intermediary for John Seller is listed as the actual seller.  

Do you have a preferred method and format for keeping track of all of that information?  

I am looking for either flips or rentals that I can use the BRRRR method.

I broker my HELOCs to TCF bank specifically because they will accept Fannie and Freddie's standard methods of calculating DTI (which your local credit union obviously is not) instead of re-inventing the wheel, with the only deviation being that they will calculate their own debt obligation more conservatively (which makes sense given that it's an interest only product in 2nd lien position). 

I would like to do this method, but have 3 little kids and moving that often sounds horrible, even though it dies make me clean out all the stuff I don't need!

Then I will use the BRRRR method (Buy, Rehab, Refinance, Rent out, Repeat) to continue building my portfolio.

There are other methods available for low or no down, but a bank isn't one of them. :)  

Did anybody finance their first property utilizing that method?

It would be helpful to discuss your level of experience and build on that.If you know nothing about real estate, starting with the more risky or complicated methods of acquisition will be frustrating for you, at best.If starting, consider getting your TX agents license if for no other reason that to get a foundation of knowledge.
