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. For more on this topic, see Dividend Growth Investing.

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. For more on this topic, see Healthcare in Early Retirement.

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 Charitable Giving Strategies.

Lifestyle design in financial independence means consciously choosing how to spend time after leaving traditional employment. Research shows that retirees who develop three or more meaningful activities report 67% higher life satisfaction.

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.

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.

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.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.

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