Rent vs Buy a Home

Buying makes sense if you'll stay 5+ years AND total cost of ownership (including transaction costs) beats renting plus investing the difference.

Term vs Whole Life Insurance

For 95% of families, term life is the right answer. Whole life mixes insurance with a poor-performing investment — avoid it unless you have specific estate planning needs.

  • + Simple, transparent
  • + Lets you invest the difference in low-cost index funds

Cons

  • − No cash value buildup
  • − Premiums increase if you renew after term expires

95% of families — anyone with dependents and a need for income replacement

B

Whole Life

Pros

  • + Guaranteed death benefit
  • + Cash value buildup (tax-deferred)
  • + Premiums never increase
  • + Permanently covers you

  • − 5-10× more expensive than term
  • − Cash value grows slowly (often 2-4%)
  • − High fees and commissions
  • − Complex — easy to be mis-sold

Best for

High-net-worth individuals ($5M+) for estate planning, businesses for buy-sell agreements — almost no one else
