I would think that AGD would have a great opportunity to come back, since they still own their house. As for aKDPhi, I didn't think they were still on campus?
They're not listed as recognized by the school anymore.
Less than 5 years ago, there were still rooming houses. They might be an option for a sorority ultimately to purchase and renovate. I doubt the BSC would be willing to sell any of their houses at this point.
