Inheritances can often lead to nasty family disputes. Many times a person will remarry late in life - which leads to who will inherit the family home. Often this is solved by leaving the second spouse a "Life Estate". This means that the spouse can continue living in the home as long as possible, until death. At that point, the "remaindermen" take title and thus inherit the property.
It's difficult to sell a life estate, because the term depends on the life of the person first granted the life estate. Neither is the remainder easy to sell, since the purchaser would not be able to take posession until the life estate holder dies.
Be sure you, your title company or your attorney checks thoroughly to see if a property is subject to a life estate.
