Is an Adjustable-Rate Mortgage (ARM) Better Than a 30-Year Fixed Mortgage in Phoenix and Scottsdale in 2026?

Local Mortgage Answers | Phoenix, Scottsdale & Maricopa County, Arizona

Quick Answer: An adjustable-rate mortgage (ARM) may offer Phoenix and Scottsdale homebuyers a lower initial interest rate and monthly payment compared with a 30-year fixed mortgage. However, an ARM isn't right for everyone. The best choice depends on your budget, how long you plan to own the home, and your ability to afford future payment increases.

What Is an Adjustable-Rate Mortgage (ARM)?

An adjustable-rate mortgage is a home loan with an interest rate that stays fixed for an initial period before it can change.

For example, a 5/1 ARM typically offers:

• A fixed interest rate for the first five years.

• Annual interest rate adjustments after year five.

• Interest rate caps that limit how much the rate can increase.

ARM loans may be attractive to buyers who want a lower initial mortgage payment but understand the potential for future rate increases.

How Much Could Phoenix Homebuyers Save With an ARM?

Let's compare two hypothetical mortgage options on a $400,000 loan.

That's approximately $4,764 in first-year payment savings with the ARM.

Illustration only. Assumes a 30-year amortization. Rates are hypothetical comparison assumptions, not current rate quotes or offers. Payments exclude property taxes, insurance, mortgage insurance, and HOA fees. Actual rates, APRs, fees, and eligibility vary.

Who Should Consider an ARM in Phoenix or Scottsdale?

An adjustable-rate mortgage may be worth exploring if you:

• Expect to move or sell your home within several years.

• Want to reduce your initial monthly mortgage payment.

• Have stable income and can manage potential payment increases.

• Understand the loan's adjustment schedule and rate caps.

An ARM can be useful for first-time homebuyers, relocating professionals, and some luxury homebuyers seeking initial payment flexibility.

When Is a 30-Year Fixed Mortgage the Better Choice?

A fixed-rate mortgage may be more suitable if you plan to remain in your home long-term, prefer predictable principal and interest payments, or cannot comfortably afford a potential rate increase.

Important: Never assume you will be able to refinance before your ARM adjusts. Future refinancing depends on interest rates, home equity, credit, income, and qualification requirements.

Are ARM Loans Available Throughout Maricopa County?

Yes. Eligible borrowers may explore adjustable-rate mortgage financing in communities including Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale, Peoria, Surprise, and Fountain Hills.

Available loan programs, pricing, and qualification requirements depend on the borrower, property, and lender.
