As some of the others have already stated, it's hard to be cash flow positive (at least in the North East markets) when occupying the property. My thought would be if you can reduce your living expenses (I'm sure paying ~$350/month in your market is dirt cheap for rent), get some valuable experience as a landlord and start working on your systems to be able to scale up (assuming you want more rentals) then that's a win and should be something to consider even though you're not cash flow positive while living there.
Typically for house hacks, I run the property evaluations 2 different ways...
1. Like how you did.. this will show you how much you will have to pay out of pocket while you live there.
2. What the scenario will be when I move out. If your intention is to only live there for a year or two, I would definitely put more weight on this calculation to make sure it makes sense as an investment.
Hopefully you find this helpful. Best of luck!
