💡 Sharp take

The math nobody shows you.

A $380,000 loan at 6.25% over 20 years = $2,778/month and $286,795 total interest. The same loan at 6.5% over 30 years = $2,402/month but $484,605 total interest. The 20-year costs $376/month more but saves $197,810 — a meaningful middle-ground for borrowers who find 15-year unaffordable.

❓ FAQ (20-year)

Common questions.

Why is a 20-year mortgage less common than 15 or 30?
Two reasons: (1) The interest-rate discount vs 30-year is smaller than 15-year vs 30-year, making the savings math less dramatic. (2) Marketing inertia — Fannie Mae and Freddie Mac standardized around 15 and 30, and most lenders default to those terms. But 20-year is available from major banks and credit unions.
20-year mortgage vs 15-year mortgage — which to pick?
If you can afford the 15-year payment, pick it — savings are larger and the rate is lower. If the 15-year payment strains your budget, the 20-year is a smart compromise. The 20-year still saves ~$95K-$130K in interest vs a 30-year on a typical $400K loan.
Can I refinance from a 30-year to a 20-year?
Yes. If you're 5-10 years into a 30-year and have built equity + improved credit, refinancing into a 20-year is a common move — it shortens total mortgage life without the payment shock of a 15-year. Run the break-even on closing costs (typically 2-3 years).
