The priority of that lien shall be determined in accordance with the following rules: (1) The lien of taxes imposed under the provisions of this Subchapter shall be superior to all other liens, assessments, charges, rights, and claims of any and every kind in and to the real property to which the lien for taxes attaches regardless of the claimant and regardless of whether acquired prior to or subsequent to the attachment of the lien for taxes."

McLaughlin clarifies, "The Machinery Act grants property tax liens 'super-priority,' meaning they trump all other liens on the property, including the mortgage liens that are usually recorded long before the tax liens arise."
3. Hess, D. B. (2011). North Carolina Real Estate Manual. North Carolina Real Estate Commission.
