Have you visited the area to get a feel for it? I don't even live in Scottsdale, but have made many trips there. I did the same for Tucson. Wife and I essentially knew what we were getting into.
A lot of your choice is how much traffic/commute you want to tolerate and what real estate price you want to bear. What your working hours will be plays a part in this too. This should be part of salary negotiation. Traffic isn't horrible, most/some of the time, especially compared to some bigger cities.
Scottsdale is a neat place.
Will this be a paid relocation? Do you have a trusted friend in AZ that you can make a pre-trip self move of guns/ammo prior to moving truck and that sort of thing?
I moved my high end stuff, guns, safe, etc. on a road trip to a safe house. I then did the moving truck thing after houses on both ends closed. I was lucky to avoid storage, only 24 hours between swapping keys.
Someone should also post to update you on our current ammo tax situation.
