The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations. For more on this topic, see Financial Independence Milestones.

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.

Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description.

Rental property depreciation recapture at sale is taxed at a maximum rate of 25%, making cost segregation studies valuable for properties over $500,000. The upfront study cost typically pays for itself within 2 tax years.

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