The Park Side community sounds wonderful, and I concur with my colleagues that pointed out that living in a gated community provides you with added security.
One thing to consider is that for the price of homes in the Park Side community (starting at $400K, according to their website), you can get a single family home in the Wiseburn neighborhood, which is located in the western part of Hawthorne. This safe & friendly community consists of single family homes and it is located in the Wiseburn School District which is a highly desirable school district and is at par with many of the other South Bay beach city school districts. Now you won't get a brand new home in Wiseburn like you would at Park Side, but you will have the wonderful school district and a safe & friendly neighborhood that continues to encourage an improvement in home values.
Contact me if you would like more information on the Wiseburn community, or other communities within the Wiseburn School District.
