(4) In any advertisement or posted notice of sale under execution, the sheriff may (and at the request of the governing body shall) combine the advertisements or notices for properties to be sold under executions against the properties of different taxpayers in favor of the same taxing unit or group of units; however, the property included in each judgment shall be separately described and the name of the taxpayer specified in connection with each property. The purchaser at the execution sale acquires title to the property in fee simple free and clear of all claims, rights, interests, and liens except the liens of other taxes or special assessments not paid from the purchase price and not included in the judgment and conservation agreements, as defined in G.S. 121-35(1).
