Same here, and with his last apartment (soph-junior year) younger S got almost his whole deposit back. I was shocked. They deducted $20 for the shower - which was completely fair IMO.
I can’t remember if older S got anything back for his senior year apartment. He would have kept it if he had, lol. His rent was only $280! But no utilities. That brought it closer to $375 I think, but still a bargain. It wasn’t the nicest place, but it was ok. The inside was nicer than the outside.
Younger S’ have been around $550-600 including all utilities which I still think is a bargain. His UVA friends were over $1000. And he had his own bedroom and bath. His last apartment even came with a queen sized bed!
