Moving from San Diego to San Francisco: a practical checklist
Before you pack, run the numbers on these five items:
- Total compensation, not just base salary. Factor in bonuses, stock, 401(k) match, and remote-work stipends.
- Housing math for your situation. Rent vs. buy changes the winner. Use our calculator above to model both.
- State income tax. Both cities are in CA, so state tax is identical - but local sales and property tax rates can still differ.
- Commute and transportation. Gas, insurance, and tolls vary by metro. Check whether your new commute is longer or shorter.
- Healthcare network coverage. If you have employer-sponsored insurance, confirm your preferred doctors and hospitals are in-network in San Francisco.
