What do you mean by crime rating? Trulia has a place on the web page for this listing where people can vote on issues like safety and schools as they pertain to this house, but that is pretty subjective and probably meaningless.
If you want to check crime statistics, you can go to the Tucson Police Department website:
As a Realtor, we are not allowed to go into detail(s) regaring Crime Rates. Just like we are not suppose to practice "Steering" and other practices regarding telling a client what area of town or neighborhood they should live in.
Please find the link below to Tucson TPD and another for all of Tucson in regards to Crime Rates. Please remember, these are only the crimes that are reported.
According to the Assessor's records, the owner's address is in Scottsdale. This website "Tucson Crime stat" can give you additional information: http://tpdinternet.tucsonaz.gov/Stats/ on neighborhoods you are researching.
