During a final "request for clarification," the only group to propose demolition made several major changes to their proposal (4 months after RFP response submission deadline).
They include 1) a 40% alteration to the height of the proposed building (from 5 to 3 stories (despite "over 60%" of community preferring 4-5 stories per MPC report, page 7), likely due to cost, capital, grant, competitive, and TIFF/tax rebate challenges), 2) usage change (from combining YWCA downtown + YWCA SBDC offices under one roof over 4 stories to only YWCA SBDC office space on 1 story + a YWCA-leased coworking operation run by an "undisclosed national operator" on 1 story), and 3) the apparent addition of a University of Chicago initiative as a tenant (likely no letter of intent; Rob Rose stated that there was not a loi due to it being premature, but also stated that there was an loi; relevant University of Chicago sources stated that there they did not issue an loi due to a desire to not sway selection, and that they could work with any developer and/or locate their office across the street in the POAH development)
Although the original RFP stated that proposals should not rely on TIFF, grants, or tax subsidies, apparently their demolition and 5-story new construction proposal did just that.
