Those are good resources for housing, but they are not the best by far. If you want to let someone else do the work for you, use the apartment locator services in the area. They really do alot of work and its free.
I can promise you there is plenty of housing in Fort Worth. All of it is within 15 minutes of the school and you can find whatever you need (low to high prices). Don't sweat it.
Just show up a week before orientation and use an apartment locator. You won't have any problems.
Good Luck!
