Hi!
If you watch HGTV's House Hunters with any regularity, you will know that California's real estate market is expensive. San Francisco is among the most expensive real estate markets in the United States: San Diego slightly less so. Sacramento is almost reasonable, but is still on the pricey side. The further one goes inland and/or from the city center, the less expensive prices are.
For example, I live in West Covina, about 40 miles east of the beach and 20 miles east of downtown Los Angeles. My house's current value is between $350,000 and $400,000, depending on how it is evaluated. (It is about 1900 square feet, has four bedrooms, 1.75 bathrooms, a swimming pool and is located on a corner lot in a residential section about a half-mile from a freeway offramp. It was built in 1952 and is gradually being renovated.) If this house were located in a middle-class neighborhood on the Westside of Los Angeles, it would probably cost at least $600,000, and probably more (but not more than $900,000, I think). If it were located 15-20 miles further inland in a middle-class neighborhood of Rancho Cucamonga or Ontario, it would probably cost no more than $350,000.
For your purposes, I would suggest some of the suburbs of Sacramento, but I am not familiar with them. Perhaps someone who lives up there can help you more.
Hope this helps!
