My aunt was asset wealthy, she owned a home (for what seemed forever) that was in a crucial part of the town, the land was highly prized, yet she had very little income. She was living on her SS, just able to pay her bills. The local city wanted to evaluate her property as commercial and basically force her out of her home so a developer could build a strip mall on the location.
So asset wealthy and cash flow poor is a real situation. Yeah, you say she could have sold her home that she and her husband built (a million years ago) and moved into a condo someplace, but that was her home... Eventually her health deteriorated to the point where she felt safer in a care facility, she sold her home and paid the the care facility with the money. There was a lot of cash left over when when she passed. She had donated it to several local charities for battered women/chindren. She had no children of her own.
