  1.  Mechanics’ liens posted by a general contractor or subcontractor within ninety days after the date on which the last of the material was furnished or the last of the claimant’s labor was performed and for which notices were properly posted to the mechanics’ notice and lien registry internet site pursuant to sections 572.13A and 572.13B shall be superior to all other liens which may attach to or upon a building or improvement and to the land upon which it is situated, except liens of record prior to the time of the original commencement of the claimant’s work or the claimant’s improvements, except as provided in subsection 2.
  2.  Construction mortgage liens shall be preferred to all mechanics’ liens of claimants who commenced their particular work or improvement subsequent to the date of the recording of the construction mortgage lien.

  4.  For purposes of this section, a lender who obtains an interest in the real estate by assignment of a mortgage shall be entitled to the same priority as the original mortgagee.
