My husband and I have my mother living with us. She is 83 years old and I do everything for her. We buy all the groceries and I fix all her meals, I do her laundry and put it all away, I change her bedding, take her to and from doctor appointments, we entertain her, we make sure she gets her exercise. We currently ask for 500.00 a month and want to raise it to 600.00 a month. Mom is refusing to pay more rent.
