You don't exactly day trade houses but it's not that difficult to sell one, otherwise we wouldn't have so many real estate agents. It's a HUGE money source in two ways: who got to a heavily gentrified area first and bought a cheap house, reaped the benefits of good jobs and increasing values for years, especially with how California sets real estate taxes. After 20-30 years of tax-free appreciation they can sell their once 500k house for 2.5M and move to a lower cost of living area.

IF you're from around here and didn't notice this pattern then you need to be paying a little more attention.
