I live in Westchester County, NY, and I am considering taking a room in the corner of my house on the first floor and turning it into a rental.The infrastructure is already in place where I would only have to put up a few walls to keep it separated from the rest of my house, but it is a large room with a closet and bathroom that I would like to rent out.It may not be much but I feel like this would be a step in the right direction and a good way to practice being a landlord.My question is: What kind of tax implication would this have on me?
