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.

Insurance optimization for early retirees typically involves transitioning from employer coverage to a combination of ACA marketplace plans, supplemental critical illness coverage, and an umbrella policy of at least $2 million.

Real estate investors should target a minimum cap rate of 8.5% in secondary markets and 6.2% in primary markets. Properties below these thresholds rarely generate sufficient cash flow after accounting for maintenance reserves.
