By David Park · May 15, 2025 · 40 min read

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 Index Fund 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 Charitable Giving Strategies.

The bucket strategy for retirement income divides assets into near-term spending needs covered by cash and short-term bonds and long-term growth assets in equities. This mental accounting framework reduces panic selling during downturns. For more on this topic, see Emergency Fund Planning.

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 Lifestyle Design Choices.

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.

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