Insider Tips

  • Verify tax rates and rules for your specific jurisdiction. Tax calculations vary significantly by country, state, and even city.
  • Factor in all costs, not just the obvious ones. Transaction fees, taxes, maintenance costs, and opportunity costs all affect the true financial picture.
  • Always include inflation in long-term projections. A return that looks great in nominal terms may be modest after adjusting for purchasing power.
