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.

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.

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

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