Deer Valley is located in North Phoenix and is a very well developed area with lots of business and commerce. It is very close to major freeways (Loop 101 and I-17). We even have a local airport in the Deer Valley area.
I hope this helps. And if you need further information, just ask.
PS: by the way, you can search for homes in the area in the link below.
Do you have an agent that you are working with already?
There is an AMC 30 screen theatre at Loop 101 and I-17, a Harkins 18 at Happy Valley Rd and I-17, also at Bell and 34th St. and others not too much further.
