By least expensive area, do you mean Eastview? That is located off of Western Avenue on the border with San Pedro. It was annexed later than the rest of the Peninsula in 1983 and is home to about 8500 residents. It was primarily annexed because the residents wanted their children to benefit from the excellent Palos Verdes School system. It is interesting to note you can read up on the crime log for the entire Peninsula in the Palos Verdes News. But, if you have a specific concern, you can always call the front desk at the Sheriff's department and ask them about any problems they know of. Generally speaking, Eastview is considered to be a good place to live and is located in Rancho Palos Verdes.
