My mother in law was one of those. A single parent mom who lived her whole life in the same house that had belonged to her parents since 1914. She had a small pension and kept an illegal suite in the basement so she could pay her taxes. The place (lot, it was a teardown) was worth over two million when she died but she was determined to die in that house no matter what it took and no matter how much better she could have lived materially if she sold, and that is what she did. There are more important things than money to many people and I don't think people should be taxed out of homes they have spent most of their lives in.
