Infinite system and money created.Keep some dry powder for the emergencies.To Your Success!

Going from 0 to 1 is an infinite return. 

Likely more than most brrrr, but with an ideal brrrr I can make infinite return.  

The cash out will be after I pay myself back so either way the COC will be infinite as well.

@Josh R. there is another option, one that would raise you're ROI too infinite, eliminate that finance rate too 0%, and via reduction in $-expense, increase cash-flow. 

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

Open-end Funds are generally defined as infinite-life vehicles consisting of multiple investorswho have the ability to enter or exit the fund on a periodic basis, subject to contribution and/or redemption requests, therebyproviding a degree of potential investment liquidity.

Play 'The Infinite Game' :)  

I believe its important to clarify the infinite return component of the BRRRR strategy.

I borrow dollars from the bank and immediately sell those dollars to owners of commercial income property that I want to own.And then I buy those dollars back over time using the cash our tenants pay us in exchange for using our space.I'm currently shorting $10M and I can't lose regardless of who wins on 11/5By the way, the dollar will always decline in value so this thesis is applicable in any election or economic cycle.Go vote for whoever you feel strongest about, but remember you have infinite more power and that which is within your direct control.
