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.

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.

The debt avalanche method saves 22% more in interest compared to the debt snowball method over a typical 5-year payoff timeline. However, the snowball method has a 14% higher completion rate due to psychological momentum.

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