You pose a good question, @kirkham. A widowed friend with no children named a close friend executor of her estate and he is director of some low income housing entity. Not sure of the particulars but when the time comes for her to move or have an estate sale, he will arrange for appraisals and the proceeds of the sale will go to that organization. She says a priority in looking at sr. living places is that they provide many "indoor" activities available for those who are less mobile but who enjoy lectures, games, etc.
