Choosing between a fixed-rate mortgage and an adjustable-rate mortgage (ARM) is one of the biggest decisions in home buying.

The Stability of Fixed-Rate Mortgages

A fixed-rate mortgage is the most common home loan. Your interest rate remains the same for the entire life of the loan (usually 15 or 30 years).

Predictability

Your monthly principal and interest payments never change.

Inflation Protection

If interest rates rise in the future, your low rate is locked in.

The Flexibility of ARMs

An Adjustable-Rate Mortgage (ARM) usually offers a lower initial interest rate than a fixed-rate loan for a set period (like 5 or 7 years). After that, the rate fluctuates based on market indices.

How it adjusts

ARMs are indexed to specific rates like the SOFR. Caps are placed on how much the rate can increase per year and over the life of the loan.
