Seven years after the date of issuance of a tax certificate, which is the date of the first day of the tax certificate sale as advertised under s. 197.432, if a tax deed has not been applied for, and no other administrative or legal proceeding, including a bankruptcy, has existed of record, the tax certificate is null and void and shall be canceled. The tax collector shall note the date of the cancellation upon all appropriate records in his or her office. This section does not apply to deferred payment tax certificates.
