This completely depends on where you go to school. My daughter knows of a girl at a less competitive school that actually has a "financial night" during recruitment. At my daughter's SEC school it is unheard of to discuss finances and according to my daughter it would be very awkward. She said, "I think your bill comes in when you pledge and that's how you find out. Or by word of mouth."
When I was an active, we had to have a poster prominently displayed with the costs during one phase of rush and we specifically had to ask the rushee if she had any questions about the financial aspect. Everyone did this on our campus.
But then a significant portion of our Greek system paid their own way through working. It wasn't financed by mommy and daddy.
