Congrats on getting into SMU!
I'm currently in the DPT program here and was plenty doubtful of Oakland as a whole before moving here. Now I love it and it if I were applying again, the city would be a major selling point. I'd recommend focusing your search around Temescal, Piedmont, Rockridge areas. They're safe, cozy, and the commute is minimal (10 minutes on the outside).
Also, SMU (at least last year), did attempt to help facilitate finding roommates through a forum (I'm not remembering all the details).
Good luck and if you have any questions let me know!
