Housing question for parents of upperclassmen or alumni

We are trying to help D navigate the process of off-campus housing for students who will be abroad for 1 semester - in her case, Fall of Junior year. She has a group of 4 to rent an apartment with for next year, and an application deposit paid for West End, but they do not have anyone to take the Fall portion of the lease (all 4 will be off-campus in the Fall.) Any tips or suggestions would be most appreciated! Feel free to PM if you wish.

I’ve got the exact same question. My son will be abroad in the fall and also needs a sublet. Is there a place to post for sublets?
