ARM vs. Fixed-Rate Mortgage
Adjustable-rate mortgages offer lower initial rates but carry risk. Fixed rates offer stability but cost more upfront. Here's how to evaluate the trade-off.
| Feature | Adjustable-Rate Mortgage (ARM) | Fixed-Rate Mortgage |
|---|---|---|
| Initial Rate | Lower by 0.5–1.5% | Higher but locked |
| Rate Stability | Adjusts after initial period (5, 7, or 10 years) | Never changes for full term |
| Monthly Payment Risk | Can increase significantly | Stays the same forever |
| Best If You Plan to Stay | Less than 7–10 years | More than 7–10 years |
| Rate Caps | Typically 2% per adjustment, 5–6% lifetime | N/A — rate is fixed |
| Qualification | Easier — lower initial payment | Standard |
| Psychological Comfort | Uncertainty about future payments | Complete payment predictability |
