The choice that is best for you will depend on your needs and the laws of your state. If you decide to rent and one of you enters a nursing home and you don’t have long-term care insurance, you will have to spend down your assets until the spouse in the nursing home qualifies for Medicaid.

If you buy a new house and end up applying for Medicaid, the house would likely not be counted as an asset, but the state may be able to put a lien on the home.
