The homestead, including a homestead listed for sale, of every family, resident in this state, so long as it continues to possess the character of a homestead is exempt from judicial sale, from judgment lien, and from all mesne or final process from any court, to the extent and as provided by statute. However, a creditor or lien holder of a mobile home classified as a homestead under § 43-31-2 prior to January 1, 1973, may not be cut off and is not subject to a homestead exemption. In addition, a homestead with a value of less than one hundred seventy thousand dollars of a person seventy years of age or older, and the unremarried surviving spouse of such person, is exempt from sale for taxes for so long as it continues to possess the character of a homestead.
