Question about OSU deposit (and then housing deposit?)

<p>We received the deposit application for our our daughter.
How early in your opinion do we need send in the $100? </p>

<p>And then is there another housing deposit she has to send in to be sure to get a good dorm room if you go to OSU? How much?</p>

<p>I am not sure when she/we will decide if OSU is where she is going.</p>
