I own a condo and want to rent a room in a typical long-term roommate situation, only to share in expenses, not for profit. My place is about 1,200 sq ft and the roommate would have a private bath within their room, but the rest of the condo would be shared 50/50. I was thinking of charging $900/month (all-inclusive) flat rate for rent/utilities. My mortgage/escrow and HOA dues total about $2125.00/month, which include homeowners insurance and property taxes.
Since I have to claim this as income, despite only sharing equally in expenses, roughly what would I owe in taxes at the end of the year come tax time? FYI:I live in California
