Huh. My Mom nailed it. She passed this morning--very sad, but also very grateful her suffering from bad arthritis and Alzheimer's is finally over after too many years. In December she was going on Medicaid as her assets were down below $4K. That's about as close to zero as you could get.
Actually this is slightly misleading in that when my dad was alive, their assets fell to where he could split off his share of whatever the number was and she went on Medicaid for her memory care and assisted living. So they actually did run out and have to rely on some government aid. We didn't do any hiding or early transfer of assets to game the system. They each had a sparse closet of clothes, furniture for a studio/room, and each had a TV. When he died last year, she got his assets and went off Medicaid for about a year until her care ate up that money. We were fortunate that the place she was staying did take Medicaid after at least a year of paying full price, and we all thought it was a very good place.
This wasn't their plan, it's just how it worked out. In Dad's final months, he lamented that he wasn't leaving behind much at all for us, but they had given us kids some money in earlier years when we needed it. And they didn't burden us with expenses for their care.
