The real issue for a married couple is the possibility of the non-ill spouse being impoverished through either paying for care for the ill spouse or due to having to spend down to reach Medicaid limits. Yes, I know that the non-ill spouse can now keep some money but it is a fraction of what most of us here would have.
Not just the allowed money, but the house, as long as the non-nursing home spouse is still living there. In Illinois, for instance, medicaid would exempt up to $500,000 in house value. In essence that would become an asset for the surviving spouse.
Here's an example that I may have posted in another thread.
When my mother went into a nursing home, my stepfather (second marriage) being of old Yankee Stock, decided that he would not let my mom become a burden on the state, and decided to sell his home (Small cottage on the bay in Barrington RI, that he bought for $2000 in 1929.) Not being aware of prices, he planned on selling for $100,000 to help pay for mom's nursing home care.
One of his daughters, decided to go to an elderlaw lawyer, who suggested that he stay in the home (with help) and let the state pay for mom's care, according to the law.
After my mom passed away, he still owned the house. Two of his grown children had very little in resources due to illness, and were heirs to his estate. Three years later, he passed away. When they sold his house they received $815,000... (actually the value of the land, since the house was a simple cottage.)
Something to keep in mind, when thinking of downsizing... especially if downsizing in value, too.
Last point... The lookback period is now 5 years. That means, if spouse goes into the nursing home, buying a house has to have been 5 years prior to being admitted. Same for gifts or most other transactions designed to safeguard assets. Legal advice a MUST!
