It really depends on what quality of life you're looking for. Do you want to live in an inland, hot in the summer, conjested I-15 traffic, suburban cookie cutter environment? Then neighborhoods like Poway, Rancho Bernardo and Carmel Valley are great.
Or perhaps you prefer a more moderate/mediterranean, semi rural to rural rolling hillside, winding country roads, where you can own anywhere from a half an acre and up. Then you may want to check out Northeast Vista, San Marcos and Bonsall.
If you don't mind a little climatic volitility (hot in the sumer and cool in the winter) then you could look at Valley Center, Ramona, Julian and even Southeast County around El Cajon & Crest areas. But be wary of fire season in any of these areas.
Or if you prefer to be a little more coastal and love a funky laid back lifestyle and international renouned surfing culture you may want to look into the Solona & Encinitas areas. You will find properties east of I-5 somewhat comparable to the inland areas. The more West you go the higher the price.
If you're West of Coast Highway 101 then your dealing with small and pricey homes on small lots with small garages unless you can afford to buy a Mc Mansion (upwards of 1M). But then, as much as I love the Coast and spend more than half of my time here, you will be dealing with Coastal influences i.e. Catalina Eddys, May Gray, June Glume, Coastal fog and just a lot of good ole fasioned indigenous morning & evening overcast skies.
Bottom line and in answer to your question about good High Schools? You will find great schools in just about all of these areas. All of my children graduated from Rancho Buena Vista in Vista and today they have all graduated from college. My younget daughter starred on a CIF championship BB team and later received a full ride BB scholarship to USD where she earned her BS degree in 4 years.
My oldest son graduated from Cal State San Marcos and today is a father of 3 beautiful children and a very successful San Diego business man. One of my other daughters graduated from the Design Institute of San Diego and is today one of California's most up and coming interior designers located in the Cedros Design District.
My Youngest son graduated from Northern Arizona University where he earned a degree in English Literature and International Communications and today runs our SD based company of 30 years with my USD daughter. They have subsequently taken our company Nationwide.
I'm not to brag about my kids. I'm just trying to drive the point home. It really doesn't matter where your kids go to school. It's more about what effort parents put into getting them through the process.
I've seen so many great and attentive parents lead their children arduously through K-8 only to drop them off on the school yard steps on their first day of high school where they then expect the school to take over from there thinking they have done their service and it's now time for their kids to step up.
Truth be known. That's where so many parents drop the ball. Fact of the matter is high school is actually where your children need more parental leadership than ever. So drawing this sermon to an end let me close by saying once again that it's more about what you are willing to put into your childrens HS education than what the particular school you choose puts into your child.
Thanks for indulging me but I'm just a silly, sensitive and proud ole father of 5 and grandfather of 12 trying to relate to a subject that has long hit a nerve. Good luck and if I can help you in anyway please do not hesitate to reach out. 760 815-6977
