<p>Pygatea-
Although in the past you were able to get your deposit refunded, beginning this year that is no longer an option. So, once you send in your deposit, that becomes your commitment to attending the University.
There are plenty of good options in housing, and I would encourage you to wait until you have heard from other schools before sending in your deposit. Most if not all dormitories will still have space if you wait until the priority deadline for EA acceptees for housing forms (April 15th, I believe), which is after you will have heard back from other schools.</p>
