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 Bond Tent Strategy.

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. For more on this topic, see Roth Conversion Ladders.

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. For more on this topic, see Frugal Living Tips.

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

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.

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

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

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

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
