Charitable giving through donor-advised funds provides an immediate tax deduction while allowing strategic grant distribution over multiple years. Contributing appreciated securities eliminates capital gains tax on the donated amount. For more on this topic, see Qualified Opportunity Zones.

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 math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.
