If you are looking for power areas, I recommend, Solana Beach, Cardiff and Encinitas. You can't go wrong with those locations in North County San Diego
Rancho Santa Fe California is arguable the best place to live in the Country and maybe the world. The public school is essential private, as only children from that neighborhood can attend. If you want a private school education for your child without the fee's try Rancho Santa Fe, CA 92067
Call a Realtor and they will advise you. I recommend calling two or three realtors.
