Temecula/Murrieta/Menefee in South Riverside county is more affordable now, and full of young families who could not afford the expensive homes in San Diego & Orange Counties.
Tracy/Lodi in San Joaquin county. Stockton is not so nice - when I was there it had a crime problem.
Lake County is affordable. Jobs? Probably questionable.
The difficulty is "good job market" and "affordable". Good jobs are in cities. Cities are generally expensive.
And, Oh dear, the question "and they are not a minority as Caucasians " is fraught with terrible problems, as it's illegal to discriminate, steer (this neighborhood is full of martians), or blockbust (as in the, martians are coming, sell now or you'll be living next to green people). Plase avoid discussion of race, gender, origin and such completely, and focus on schools, crime and a well maintained neighborhood.
Look for schools with good results "California Distinguished Schools", becuse schools with good results and low crime tend to run together. All proice districts release crime reports, Schools also release reports which are somewhat difficult to analyze, and seem to be designed so one can't compare school districts.
I an agent in Lake County, CA and new to this site, so I am not sure where you are at this point in your search, but thought I would touch base. We are 3 hours north of San Francisco, 2 hours east of Sacramento and offer some pretty good pricing on homes in the area. I would love to send you a list of what's available, if you are still searching. Give me a call or email.... Jeri Lynn Meyer (707) 245-6560 or firstname.lastname@example.org
By "geat home market" in California, do you mean a geat value?
I can only tell you where I would (and have tried) to move my parents and family near me (Sacramento). First there is the Galt or Lodi area. Small places, you can get nice homes for 350k and VERY easy freeway access and short commutes to Elk Grove/Sacramento on the North and Stockton on the south. You're going to find better schools than in Stockton but still have ready work available to the north and south only 30 minutes away. Much lower crime too.
Next just to the north of Sacramento about 15-20 miles is Woodland. Everything you can possibly want or need there. Again, all for the same reasons... lower crime, good schools, and many residents have been there for a long time. Downtown Sacramento and Arco Arena are 20 miles away and host all the art, plays, concerts, sports games.
Last, my family is currently in a place that is about 20 miles West of Fresno. Only 15k population... very good schools... very low crime... but near a very big city of Fresno for the job market. My niece lives there and I don't think I would want her anywhere else. (I have added a link to the homes there.)
This is only a start but I am sure I could point you in the right direction.
If you'd like to discuss this in further detail, please feel free to contact me.
I hope I was able to help.
Best of luck,
