House hacking in San Francisco

[Anthony Lynch]

I was wondering if there is anyone out there that has successfully house hacked in San Francisco/bay area and live there rent free. I have been doing the numbers and Struggling to see it working without me actually having to contribute to the mortgage payments along with the tenants payments. I have invested out of state but I would love to invest where I live. I don't mind contributing to mortgage rather than me paying rent for another place but that would seem to defeat the purpose of house hacking. Would love to hear peoples thoughts.
