Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts. For more on this topic, see Municipal Bond Investing.

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. For more on this topic, see Small Business Retirement Plans.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
