Above and beyond our additional expenses. In addition to some of the typical additional chores (laundry - including some soiled, meals, medicine, etc) she interupts most conversations between our kids and us with the same 15 stories about her childhood. She's very sweet, and loves to tell these stories, but it keeps out (late-teen) kids from having normal conversation with us at the dinner table.
She is saving about $400/month by living with us and that figure will rise to $1,100/month once her house is sold in about a year. Her estate, including the house, is about $300,000.
Is there a fair amount to charge the estate for the caregiving and the additional expenses? Both my wife and I work. In about a year, we'll have to have a companion come in while we're at work, but for right now she's ok as long as we call her and remind her to eat lunch and take her medicine. Our daughter gets home from school at about 2:30 and helps out.
