Perhaps if you leave the socialist country of California for Texas or Florida you can eliminate those SALT hits altogether.
Unfortunately, leaving isn’t practical because we’ve been in our Silicon Valley house for 34 years (big capital gain). Paying the government to leave would astronomical - a multiple of what we paid for the house. Our goal is to get that money to the kids, not to the government. To do that, one of us has to croak in the house.
All the weirdness in tax laws, hot real estate markets, the tech boom, etc have put handcuffs on a lot of people over age 55. We are very fortunate to have settled in this area from that perspective. Not so fortunate having seen the state politics shift toward open-borders communism over 40 years.
