Notwithstanding the above provisions, the lien of a person who has furnished labor, services, or materials in connection with the construction of improvements to real property is superior to the lien of a recorded mortgage as to indebtedness actually incurred after filing of the notice of the mechanic's lien required by Section 29-3-90 and service of the notice on all prior recorded mortgage holders. Service of the notice on prior recorded mortgage holders must be made pursuant to Rule 4 of the South Carolina Rules of Civil Procedure. The priority of the mechanic's lien extends only to the mortgage indebtedness actually incurred after the filing of the lien and service of the notice on all prior recorded mortgage holders.
