Frank, what I do is I first focus on one metric that "trumps" everything - i.e., it's my most important number. Once a deal "passes" my minimum threshold for that metric, I can look into the details of the P&L of the property.
For me, my focus is VALUE-ADD. I don't buy anything unless I know I can increase the value by addressing the property's deferred maintenance, or updating the apartments or solving the property's financial underperformance (or all of the above).
I created a tool that allows me to evaluate a deal in 5 minutes or less. It will even say "Yes" or "NO" to the question: Is this deal worth looking into? Here's the screenshot:

If it says "Yes" I look at the detailed T12 (trailing 12 months) and I look for those economic inefficiencies (like low rents, high repairs and maintenance, high vacancies, high capex, etc) that I can improve.
As others said, you need to read books/listen to podcasts/attend webinars and seminars to know apartment underwriting. Then you need to do a lot of practice underwriting until you get an "intuitive" feel for it.
I can give you the tool above if you want. Let me know.
