March 15, 202610 min readMortgage

One of the most important decisions you'll make when getting a mortgage is choosing between a fixed-rate and adjustable-rate mortgage. Each has advantages and disadvantages.

Fixed-Rate Mortgage (FRM)

The interest rate stays the same for the entire loan term.

Pros:

  • Predictable monthly payments
  • Protection against rate increases
  • Easier budgeting

Cons:

  • Higher initial rate than ARMs
  • Don't benefit if rates fall

Adjustable-Rate Mortgage (ARM)

The rate changes periodically based on market conditions.

Pros:

  • Lower initial rate
  • Save money if rates stay low
  • Good for short-term ownership

Cons:

  • Payments can increase significantly
  • Uncertainty over future costs
  • Complex terms to understand

Which Should You Choose?

Choose Fixed If: You plan to stay long-term, want stability, or rates are historically low.

Choose Adjustable If: You plan to move in 5-7 years, expect income to grow, or need a lower initial payment.
