Decision Checklist Before Moving to San Francisco on $100K

  1. Treat this as a short-term landing budget, not a comfortable long-term plan.
  2. Target lower-rent neighborhoods or nearby cities before moving, because the savings buffer is too thin for emergencies.
  3. Avoid adding car payments, student loans, or childcare costs unless income is rising soon.
