I did my undergrad at Purdue and here is what I can tell you about housing. Usually stuff that is close to the vet school (within walking distance) is going to be more expensive and if it's not it's really crappy. Then in regards to area I would say try to stay in West Lafayette. Not to say Lafayette is a bad area but if you stay across the bridge in West Lafayette you typically are guaranteed a safer place. You can usually find great housing off campus which takes less than ten minutes to drive and you will get a nice place that is usually huge, plus you won't need as many roommates. Also consider looking at the DVM housing list of the Purdue vet schools website. I know I'm not only looking for a roommate but so are plenty of other students. Again congrats on your acceptance evilsquirrel, can't wait to be classmates!!
