There is actually a
negative incentive to sell, because your property taxes will almost certainly go up if you buy another home.
It's gotten to the point that we have ballot amendments carving out exceptions for senior citizens, so they can take their old property tax rates with them when they buy new homes, but only if they move between certain counties that have a reciprocity agreement, blah blah blah. Clearly not the kind of policy a sane system would result in.
If you've owned a home in California for more than about 20 years, and you aren't in one of the senior citizen categories that is exempt from tax increases, it just doesn't make sense to sell your home unless you leave the state.
