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.

The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45. For more on this topic, see Backdoor Roth IRA.

Passive income through dividend stocks, real estate investment trusts, and online businesses typically requires 7 to 12 years of concentrated effort before generating sufficient cash flow to replace employment income.

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.

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.

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