Fixed vs Adjustable Rate Mortgage — Which Should You Choose?

Side-by-side comparison of 30-year fixed, 15-year fixed, and 5/1 ARM — how each is priced, where the risk lies on ARMs, and how to decide based on your planned hold period rather than guessing on rates.

What you'll learn

  • How the 10-year Treasury yield drives 30-year fixed mortgage rates
  • How ARMs are structured: initial fixed period, index (SOFR), margin, and caps (2/2/5)
  • Why 15-year fixed rates are 0.5–0.75% lower than 30-year fixed
  • The break-even hold period where an ARM saves vs a fixed rate
