What about "First year rented" though? Would I select that in addition to "I rent a part of my home" for each bedroom?
Assuming the first year for each bedroom was 2022, then absolutely, yes. Remember, you're treating each room "AS IF" it's the only room rented. The fact that the third bedroom includes the rest of the house too, doesn't matter, based on the fact that since you moved out, one hundred percent of the property is rented out as of Dec. 2022.
