How do you analyze your multi-family traditional house hacks?

[Tyler Natterer]

What metrics, formulas, and online calculators have all of you found to be the most helpful when looking to house hack? For more detail, I am looking to house hack with a 3.5% FHA loan next year or the year after since I am a junior in college. I am looking to analyze these properties for the best cash flow and was wondering what metrics or formulas I should be using that gave all of you the best success. Also if you have any links to spreadsheets or ways to analyze deals I would be appreciative if you could link a copy as well as any input you have.
