NJ Resident looking to buy first house in Philly

[Marek Los]

Hi there!  I currently have one house that I house hack in Trenton, NJ and so please bear with me but I am not familiar with the Philly side of things at all.  I really like the Philly market (specifically Port Richmond) and would like to buy an investment property here, but don't know how this would work with the Philly city tax.  I don't intend to live inside the house, just simply rent out the unit and get some cash flow from it.  If I remain a NJ resident and this is clearly an investment property, would I be liable to pay the city tax on my income?  Just to be clear, I have no problem paying my fair share of any profits to the city but I don't want to become classified as a Philly resident so that my regular W2 gets hit with the city tax, that's my primary concern.  Sorry for the dumb question but I kept looking around the Internet for answers and didn't see anyone with quite the same situation.  Thanks!
