I have recently opened a line of credit to be able to do something like the BRRR method, by buying a cheap/ rough property and improving it with the line of credit and then refinancing it once its completed in order to "recharge" the line of credit and do it all over again.

If they are using methods #1 or #2 above, their markup is actually built into their pricing!

I'm trying to understand this a bit better, hence the reason for the thread, to weigh in my proposed method versus your proposed method. 

I bought it this year and originally I wanted to do the BRRRR method on it but now I just want to get out from under it.

Is there a better method for someone doing their first deal?

Find out how he or she wants to book these types of transactions and then stay consistent with that method.

I've only gotten a few 4plexes refinanced and it seems they tend to use both comps and the cash flow method.

My first Bigger Pockets book was The Book on Investing in Real Estate with No [and Low] Money Down by Brandon Turner in 2018 and to be honest I was pretty skeptical about some of the methods for owner financing so I decided to keep learning more about real estate investing.

The only methods I can seem to find is opportunity zones.
