want to understand the numbers in finding & analyzing properties

[Bobbie Dancy]

Hello I'm new to investing and trying to figure out the proper system to identify and analyze homes. After I've done my comps on a property. The asking price $75,000; the comp is slightly superior and sold for $70,000. (It was the only property that actually compared accurately.) What is the next step?...after doing the comp. I'm just practicing because I want to be good at finding good investment properties and analyzing them. 

My plan is to house hack and BRRRR. First and foremost I want practice good habits as an investor. Understanding the numbers in rental properties. I don't want to overpay because I think I like the house. I rather be accurate on my selections.
