Should I do a 15-year or 30-year mortgage?

Quick Answer

A 15-year mortgage saves $100K+ in lifetime interest vs. a 30-year and builds equity 2–3x faster, but costs ~50% more per month. Most buyers should take the 30-year for cash flow flexibility and prepay voluntarily — same payoff with built-in safety margin.
