I struggled with this a lot when I got a roommate last year that’s paying rent.
I’ve come to terms with it recognizing that we are supporting each other. I’m supporting them by providing them a stable and affordable place to live, and they’re supporting me by helping me make ends meet, especially in a time when I’m unemployed. I’m not profiting off of them or taking a living space from another family. I also plan to calculate the portion of equity they contribute to the mortgage and give it to them whenever I wind up selling.
