For some people who are waiting on UT before submitting deposits to other schools, I know a few individuals who are in the UTCoP right now that submitted deposits for other schools, but withdrew after hearing of an acceptance at UT. If you don't hear by this weekend, it might be good to secure your spot in another program and just forfeit the deposit if you hear of an acceptance from UT in the second round (which should be the week after Spring Break) if UT is your first choice. I don't think they told anyone over Spring Break, and even if you called them, chances are you may not have been reviewed by the ad-com yet; so I don't know if calling in regards to a deadline for another school will help much. Of course, what you decide to do is up to you.
As for places to live, I would suggest North campus (29th street and higher). I live about 5 blocks away from campus (a 15 minute walk) and it is definitely much more tame than West Campus; I rarely have a problem with noise on the weekends. My family bought a condo where I've been living the past 3 years and it ends up being about the same as paying rent each month in terms of cost. It may be a good investment since you'll be here for at least two years, maybe three or four (depending on rotations).
