Mary, you may want to have your friend check about the cost of getting the car dings fixed without going through the insurance company. Sometimes out of pocket is cheaper in the long run because you premiums may go up next year and that may be more than the cost of paying for the repair.
Mary, may I suggest that your Aunt be allowed to make the changes in her home life at the pace she is comfortable with. If she has lived in the rambling house for years giving it up right after the death of her husband may be too hard. Some spouses do not get rid of the clothing and other personal items for several months and some enjoy going into the closet to smell their loved ones clothing.
I realize this may not be feasible because of money and safety but considering you Aunt's age it may be best for her if things can be arranged so she make the transition slowly.
