|---|---|---|
| 3.0% | 10% | Invest strongly wins |

| 8.5% | 10% | Roughly equal |

The Psychological Case for Payoff
Numbers favor investing, but payoff wins on:
- Debt-free home = massive security and flexibility
- Guaranteed 6.5% return vs variable market
- Job loss resilience: no mortgage payment = lower monthly needs
- Many people would spend the $1,000 instead of investing it
