How to practice BRRR deals

[Eric Davenport]

Hey everyone! 

I am working on becoming better at analyzing deals and listening to the advice of @Brandon Turner to analyze a deal every day to become more comfortable. I am very interested in the BRRR strategy and want to hone my skills on this kind of analysis, but am unsure about how to calculate repair costs with looking online and crunching numbers on the calculator. I know this question goes a million layers deep, but do you just go by the pictures that are posted online, or use a general calculation per square foot?

Thanks for any insight!
