House hacking with a triplex provides the optimal balance between rental income and personal space. Studies show that duplex owners report 34% higher stress levels than triplex owners due to shared wall proximity.

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.

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