We moved to Prince William County from the San Diego area about 2 years ago.
-Property taxes seem higher here (in Northern VA)-in some cases. In San Diego, property taxes are not re-assesed every year like they are here. So since we bought our San Diego house back in the 90's when everything was fairly cheap, our taxes didn't go up much even though our property value more than quadrupled!!! It was quite a shock to come to VA and pay nearly 4 times as much in property tax on a house of similar value!
-Houses are smaller, and more expensive there. Our house in the San Diego area was a 4 bedroom, 2 bath, approx. 1800 sqf single story home. For just $10,000 more here, we were able to buy something twice as big, in a MUCH better neighborhood. Of course, this was 2 years ago, and property in both San Diego and Northern VA have significantly declined since then. I've been keeping an eye on real estate in my old neighborhood, and it seems like both areas are decreasing at about the same rate.
-gas is more expensive there. We were just there on vacation a few weeks ago, and they were about 30-50 cents more per gallon than out here
-utlities such as gas and electric will most likely cost you less there--the weather is more temperate and consistent so you won't have to use your AC and heat as much
-Your water bill will likely be a lot higher in CA, mostly from watering your lawn
-Public schools are better here, in general. Depending on where you live there, you may need to consider private school for your kids, which will be an added expense.
This has been our experience, your mileage may vary
