For the first part about when do we rent out:
We just bought the house last year, we rented out a room to a roommate a few month later (in 2022).
For the second part about inputting income/expense: Yes, that is the plan, we're gonna put 1/2 of the income and expense on Schedule, 1/2 for me, 1/2 for my GF.
Thank you so much for the help!
