Need Help with BRRR Method (includes photo)

[Michael C.]

Hello everybody! i am new to real estate and have recently tried to learn how to do the BRRR method, i wrote an example with rough estimate numbers. I just want to make sure i am understanding and doing it right. I am honestly just looking for advice to further my education on this topic. (Writing things out is the best way i learn) This example is from a combination of things i have learned from bigger pockets as well as books i have read and market values i have been trying to keep up with.

I would like to build a large portfolio of rental properties to build a passive income. 

Thank you for your time and help!!
