I'd only need to be out of Cali for two years.
I'm one of those FIRE people. Financial Independence Retire Early.
Most FIRE people have all their money in VTSAX. So, when they hit their FIRE number, they don't have a massive tax problem with unwinding their risk.
Unfortunately for me, none of my money is in VTSAX.
All my money is in Google (48%), AMD (15%) NVDA (13%), AVGO (12%), VOO (10%), META (2%).
I have to unwind my risk, which means selling out of huge percentages of these positions. Positions that have doubled. Some of them have tripled. Which means huge amounts of LTCG (Long Term Capital Gains)
Obviously, I'm blessed to have the problem of too many LTCG's and thus too much taxes, but I still have to deal with the taxes.
I could unwind the vast majority of my risk over a two year period, and I might save like 15 to 18k each year in doing so.
