What are the top metrics to assess if a flip performed well

[Michael Curry]

My brother and I are about to finish our first flip and are set to close in a month. Before we even made the deal we knew (or had fairly accurate estimates) the ARV, repair costs, loan costs, set a desired profit, closing costs on both ends. We are going to hit the desired profit we set out in the beginning. While this is good news I want to know if there are other metrics that people use to judge if a deal went well? For example how long did the project take, did you make enough money for how long you held the property, was there something unforeseen that impacted the duration of the flip or the desired profit?

My end goal is to make a report for each flip so we can analyze how well each one went and if we are improving over time or do we have areas for improvement. 

Long story short, what are other useful metrics besides for hitting your desired profit?

Thanks!
