Real estate would be infinitely easier if those pro-forma spreadsheets always translated to reality.

Should everything go well, COCR is infinite if I completely cash out, but in a B- / C+ residential pocket with minimal appreciation, is the cash flow sufficient?

That is a net-zero BRRRR has infinite (or undefined for the math geeks) CoC.

It's a reference of how strongly your money is working for you.You have 100k invested, and net 1000 monthly = 12% CoCyou have 1MM invested, and net 1000 monthly = 1.2% CoC same cash flow, but a much worse way to spend your money.This applies across leverage too:$0k invested, Mortgage the entire amount +net 100 monthly = --% CoC ( infinite)$20k invested, Mortgage a percentage of the unit + net 200 monthly = 12% CoCSo the cash flow is higher, but it comes at a much higher cost.

Companies like the ones you list make you go through many of the same steps as a hard money lender like submitting all the specs for your property, and charge points, fees and high interest, often at similar LTV (loan to value ratios) just like hard money lenders.The big advantage to crowdfunding portals, as I understand it, is in volume - if you are doing 100 flips you'll want an infinite supply of money.

In return, I'm getting to do a deal probably 3x larger than I would be able to do on my own because my equity partners are infinitely more comfortable.

You'll see lots of "infinite bankers" and "be your own bankers" here on bigger pockets.

How the profit pot gets shared can be done an infinite amount of ways, but 6-10% preferred returns followed by some splits past that are common.

I want infinite returns becuase I have so little money to invest so I want to buy with no money down.
