In June of 2015, the Wichita Area Association of REALTORS® (WAAR) joined efforts with four other REALTOR^® Boards (Butler County. Harvey County, and Winfield) to form the REALTORS^® of South Central Kansas (RSCK). This collective regional effort resulted in creating a new Association representing all of south-central Kansas. 

In July of 2024, RSCK expanded further following a merge with Great Plains Association of REALTORS® (GPAR). The merge resulted in the addition of 13 counties and the Saline County Council to RSCK. Each Council within RSCK and has its own Board of Director representation.
