How to house hack properly (Duplex)

[Tkai Savage]

When house hacking are you looking for positive cash flow or enough just to pay of your mortgage. How do you properly run the number on a property I know it's a little different than a standard single family home. I can't seem to find the average rent for a duplex to get a number on how much I will be able to charge. I know after I leave the unit the cash flow will be much higher than with me living there.
