What licenses (If any) are required in New York?

[Austin Wark]

Hey Bigger Pockets,

     I'm getting closer and closer to to taking the leap and buying my first property! I still haven't been able to find any good information regarding licenses and permits in New York State though. I understand that there are realtor and broker licenses, but is any of that needed if I plan to just buy and hold, and rent out a unit or two? My plan for my first property is to house hack it. Ill purchase a duplex, rent out one unit and live in the other one for little to no cost. I'm also curious about fix and flips as well. Any feedback is appreciated!
