Sounds like you are outside of the state of Arizona? What are you looking for in a property? Is this for you, to rent, an investment? There are many, many factors when choosing a house and I wouldn't use what other people say to meet my criteria. I imagine you have a favorite color? You would not have someone else tell you what your favorite color is, right? Work with a local Realtor, go over your search criteria & they will present you a list of properties to view and choose from.
Are you going to be visiting Tucson? That would be best, drive around, see the different sections of town. First thing I would send you is the buyers advisory, which contains a wealth of knowledge, including live links for items like current crime rates.
If you are not working with a local Realtor, I urge you to interview a couple and pick one to work with. I have helped many buyers out of state, and out of country find the right house for them.
Best of luck.
