The county may sell any property acquired with authority provided in this Section, or assign any tax certificate to any party, including, but not limited to, taxing districts, municipalities, land banks created pursuant to Illinois law, or non-profit developers focused on constructing affordable housing.
The assigned tax certificate shall be void with no further rights given to the assignee, including no right to refund or reimbursement, if a tax deed has not been recorded within 4 years after the date of the assignment unless a court extends the assignment period as provided in this Section. Upon a motion by the assignee, a court may toll the 4-year deadline for a specified period of time if the court finds the assignee is prevented from obtaining or recording a deed by injunction or order of any court, by the refusal or inability of any court to act upon the application for a tax deed, by a municipality's refusal to issue necessary transfer stamps or approvals for recording, or by the refusal of the clerk to execute the deed. If an assigned tax certificate is void under this Section, it shall be forfeited to the county and held as a valid certificate of sale in the county's name pursuant to this Section 21-90. The proceeds of any sale or assignment under this Section, less all costs of the county incurred in the acquisition, operation, maintenance, and sale of the property or assignment of the tax certificate, including all costs associated with county staff and overhead used to perform the duties of the trustee set forth in this Section, shall be distributed to the taxing districts in proportion to their respective interests therein.
Under Sections 21-110, 21-115, 21-120, and 21-190 , a county may bid or purchase only in the absence of other bidders.
