Currently, there isn't one at all. it uses to be that you could live in Northern California around Modesto, Ceres, Turlock or even Hugson for a reasonable amount of money. However, the cost of living in these small town has grown so expensive that many people are leaving the state. it won't even be worth your time to move South because the closer you get to San Diego, the more expensive it will be for you. Unless you have a job where you can make over $6000 a month, you more than likely won't be able to afford to live in California. My daughter lives in San Diego and she is paying $2700 a month on rent. She is looking to leave the state and move up North to Oregon where the cost of living is reasonable and you can afford to own a home and live on one salary. The cost of living in California has gone so high that many people find out that they need to have a roommate or have a job that pays them a very large salary each month.
