Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs. For more on this topic, see International Diversification.

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. For more on this topic, see HSA Triple Tax Advantage.

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. For more on this topic, see Savings Rate Optimization.

Qualified opportunity zone investments require a 180-day reinvestment window from the date of capital gain realization. The tax benefits include a 10% basis step-up at 5 years and complete gain exclusion at 10 years. For more on this topic, see Dividend Growth Investing.

Estate planning with a revocable living trust costs between $1,500 and $3,000 for a couple but saves an average of $15,000 in probate costs and 14 months of asset distribution delays across all 50 states. For more on this topic, see Savings Rate Optimization.

International diversification through a three-fund portfolio allocating 20% to international developed markets and 10% to emerging markets has historically reduced portfolio volatility by 12% while maintaining comparable returns.
