As I mentioned in my original post, I am inquiring for my mother who had a stroke a couple years ago. She thought she had planned ahead, her house was paid for, she had a meager savings, and she had a steady retirement income. She wasn't wealthy by any means, but she had enough to last the rest of her life. Then she had a stroke, and had to move to an assisted living home. At those prices her income and assets from selling her home will be gone in a few years, perhaps less if she has another expensive medical issue. At some point she will run out of money and need to apply for medicaid assistance.
It's not always that simple. For starters, my mom cut off contact with everyone for over 20 years so she wasn't willing, or didn't have the forethought, to give us money for her future needs. Bad choices on her part, but it's too late now to worry about all that.
Also, medicaid looks back five years from the time you apply. If you've given away money during that time, they count that as an asset that has to be paid back before they will provide assistance. Mom "should" have more than five years left with her own money, but it would only take one medical situation to ruin that plan. So the setting aside money option has already passed...
My wife and I are planning to retire in five years, but retiring early doesn't mean we are retiring wealthy. We will be able to live comfortably ourselves, but we aren't wealthy enough to support my mother too. For that matter, we couldn't afford to support her now while we are both working. We also need to help care for my wife's mom so paying ourselves is just not an option.
