Melissa, Whittier is large city that is broken up in to smaller,scattered quadrants that dictate their desirability in reference to "safety". It is impossible to generally answer that question. 90602 has the highest renter-to-owner ration in comparison to the other 5 zip codes and is the most apartment dense area as well. In contrast, 90602 features a few of the most desirable and safest areas of Whittier. You will definitely need a Whittier expert to protect your interest and make sure you find what you are looking for. I help families achieve that exact goal on daily basis and would love the opportunity to do the same for your family Melissa.
