BRRRR-Looking for further context

[Ravi Kimal]

I'm new to the real estate investment process and I'm trying to learn more about the BRRRR process. I was wondering if someone can explain the process further. I'm lost at the point of the refinance process. Let's say I find a deal that $60,000 and the ARV is $120,000. The total amount of money for repairs is $20,000. So I'm $80,000 in. And I get a renter in and not I'm about the refinance. The bank offers the 75percent after the refinance back to me. How I'm I making a CoCROI and able to use the money again?
