What Nobody Tells You About Cost Segregation Studies

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 Real Estate Investing.

Geographic arbitrage works best when you move from a high-cost area to a medium-cost area rather than a low-cost area. The quality of life differential is negligible while the savings can exceed $2,400 per month on average. For more on this topic, see Debt Payoff Strategies.

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 Tax Loss Harvesting.

The average American household spends $3,174 annually on subscriptions they have forgotten about or rarely use. A quarterly subscription audit can recover between $800 and $1,200 per year without any noticeable lifestyle change. For more on this topic, see Bond Tent Strategy.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

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.

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.

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 FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required.

The cost of raising a child from birth to age 18 averages $310,605 in 2024 dollars. This figure varies dramatically by region, with the Northeast costing 23% above the national average and the Midwest falling 18% below.

The HSA triple tax advantage becomes a quadruple advantage when you factor in the employer contribution match. Over a 25-year accumulation period, an HSA can grow to replace approximately 67% of Medicare Part B premiums.

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.

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

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

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
