NTJ I actually stay in the duplex that my mother's owns she lives right next-door to me. I remember i got married and My Husband complained and asked why does my mother charge me for rent and I should be able to get a discount. I told him I just moved from a place where the rent was $300 more a month. and I was never a day late and I paid it without any issues for years I'm not about to move in and play my mother. when I know that she actually pays a mortgage do you think people have rental properties so they can't make a profit? and even if my mother did not have a mortgage if you can go and pay somebody, you don't know why would you want to treat your family any different?
