Hello BP family!

So, Iv'e been analyzing properties on the BP rental property calculator. All of the properties being analyzed I plan to house hack. When I plug the numbers in, I run into negative cash flow If i do not include my share of the rent/money I could be saving by house hacking. If i input the rent I would be contributing for the unit, it is positive. 

I see that this could be a newbie mistake. Is there a better way to be analyzing these reports for a house hacker scenario? 

Thank you!
