Thanks for finding Trulia and giving me a chance to answer your question. Let's tackle the San Bernardino County crime rate first :-) San Bernardino County is the largest county in the world so, unfortunately, it stands to reason that it would have a crime rate per capita that would be equal to it's size. That being said, Rancho Cucamonga, while it is within San Bernardino County does not share the county's reputation.
Rancho Cucamonga, which also encompasses Alta Loma, is a wonderful place to live, the schools are great (my best friend is the head librarian for Los Oso's High School), there are ample parks, a beautiful mountain view from just about everywhere in the community and plenty of properties to choose from. You can find everything from brand new townhouses to beautiful 1 acre + estates. Oh, and don't forget that because Rancho Cucamonga is nestled within the Inland Empire and San Bernardino County, the tax base is lower. A good thing :-)
Currently in Rancho Cucamonga we have 1243 homes available and 14.6 months of inventory on the market, so this is a great time to buy there. I know of several beautiful homes, near great schools that are currently available in the area. Please feel free to give me a call for more information or if you would like to see any properties there in Rancho, or in Upland or Claremont (two other nearby communities with wonderful school systems).
I look forward to hearing from you soon. Take care,
