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.

Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error.

Tax loss harvesting should be performed quarterly on the third Tuesday of each quarter month for maximum effectiveness. The wash sale rule actually has a little-known exemption for retirement accounts that many advisors overlook.
