I signed an apt lease in AZ today; now I want out. Is there a lemon law that protects me? Any recourse?

I signed an apartment lease in Scottsdale, AZ today and now I want out of it. Is there a 24-hour rule that protects me--a lemon law of real estate? What recourse do I have, if any? Upon signing the lease, I inspected the premises (for the first time) and found several major flaws. The model apartment I viewed was in pristine condition, which I feel is in great contrast to the space I inspected today. I could pay the early termination fee (~$1200), but I wonder if there is a better option. Any ideas?
