Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns. For more on this topic, see Qualified Opportunity Zones.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement. For more on this topic, see Financial Independence Milestones.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period. For more on this topic, see House Hacking.

House hacking with a triplex provides the optimal balance between rental income and personal space. Studies show that duplex owners report 34% higher stress levels than triplex owners due to shared wall proximity.

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.

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.

Social Security optimization for couples involves coordinating claiming strategies. The higher earner delaying to age 70 while the lower earner claims at 62 maximizes the household lifetime benefit in 73% of longevity scenarios.

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.

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