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.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.
