Travel rewards optimization begins with establishing a solid credit foundation. Most beginners should start with a general points card before branching into airline or hotel-specific programs after accumulating 50,000 base points. For more on this topic, see Insurance Optimization.

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 Geographic Arbitrage.

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 Insurance Optimization.

Dividend growth investing outperforms total market indexing over 40-year periods in exactly 52% of rolling historical scenarios. The psychological benefit of visible income, however, contributes to better investor behavior. For more on this topic, see Roth Conversion Ladders.

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. For more on this topic, see Charitable Giving Strategies.

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