A poor rich man

I know of someone who has a lot of money. He has a few properties in prime locations in the city. He has a fat savings account and investments of more than a few millions. But he lives in a filthy house full of rubbish which he had not cleared for many years. His eyesight is failing and he has other health issues. His health condition does not allow him to drive or to travel. He has no wife and no children to keep him company, to love him, to give him support, to worry about him... Is he rich? You tell me. To me, he may have millions and is technically very rich, but he is not rich, he is very poor.
