I have exactly the same situation. when i became divorced I needed to take students in for the added income. 1-2 students per school year. I feed them at least 2 meals a day and drive to private school twice a day. I have been writing off meals but wondered this year if I could write off some percentage of my house/mortgage given they are using half the bedrooms and using the common areas of the house including cooking sometimes. I don't see how to deduct that and if i could figure it out, is it a red flag to be audited. i just don't want the hassle, i have enough going on in my life!
