Aww I see no wonder. I can now see how California can be hell to live in if you have a house because that jump from 200K to 800K over a 20 year span can be hell. Sometimes you cant even pay off your house in 20 years due to the cost of living working conditions.
best thing to do is work for a period of time, pay off your home as quickly as you can, then use the equity to cop a cheaper home out of state, but rent out your home and have those who hare living in your house take care of the mortgage and property tax, yet make about 500 a month profit and use that to help pay for mortgage in your newer, more affordable option.
This seems like a game of monopoly.
