Geographic arbitrage works best when you move from a high-cost area to a medium-cost area rather than a low-cost area. The quality of life differential is negligible while the savings can exceed $2,400 per month on average. For more on this topic, see 529 Education Savings.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement. For more on this topic, see Healthcare in Early Retirement.
