built detached garage at my home with apt over it - finished in June 2020. Took out a second mortgage to pay for it. I cant figure out what to select in turbotax to get the right breakdown on schedule e. Multifamily or single family and then on next page do I check I am renting part of my home and or rent out a unit in a multi unit property. It is expensing too much toward the apartment, For example, turbo tax is allocating too much of mortgage interest rather than just the interest on the second loan. would it be better to just consider it a totally seperate single family residence and then calculate shared expenses based on square footage such as utilities and property taxes?
