BP community - pleas share with me your pro forma and/or how you analyze a deal.

I love the BiggerPockets calculations, don't get me wrong. I am trying to understand the numbers a bit better and I do better by plugging in formulas and seeing the numbers change.

I am especially interested in: 

-the layout of your pro forma

-the percentage you estimate in vacancy, repair/maint., cap ex, misc

-rough estimate for utilities etc

I know every market is different but thats why I am asking. I am curious as to how the numbers fluctuate accordingly.
