Running the numbers on a BRRRR Deal

[Adam Snow]

I am new to real estate investing and am trying to learn the BRRRR method. I have a question about running the numbers on a possible deal.

Purchase Price: 65,000

ARV: 150,000

Refinance amount (75%): 112,500

This may be way over thinking this but I just needed to clarify something. When I am running the numbers do I look at rent vs the refinanced amount. Like in this above example. If I believe the house could rent for around 900 a month, do I look at that at the 112,500 amount? 

Hopefully that makes since! I think I might be confusing myself right now.

Thank you all so much I am loving all the information for BPP
