Property portioned out

Would like a method to portion out a percentage of a property that is rented out. For example, I rent out a detached in-law suite in my home and claim those expenses/income on my taxes. The problem I have with Stessa is that it’s taking the entire mortgage payment as debt when it should only be 1/3rd of it.

I recommend this support article on House Hacking with Stessa. It should answer your question and go more in-depth on ways to account for house hacking.
