Fixed vs. Adjustable Rate Mortgages: Which Is Right for Your First Home?

If you are reading this, you are probably thinking, "I am finally ready to buy my first home, but I have no idea which mortgage to choose." Good news: you are not alone. Let's have a conversation about the two big choices you will face: a fixed-rate mortgage and an adjustable-rate mortgage. I have been guiding buyers through this exact decision in West Covina and the San Gabriel Valley for 35-plus years, and I'm here to help you choose with confidence.

Here is the honest truth up front: there is no one-size-fits-all answer. The right loan depends on your timeline, your budget, and how much uncertainty you can sleep with, and I want you to understand the trade-offs before you sign anything.

What Is a Fixed-Rate Mortgage?

A fixed-rate mortgage locks in your interest rate for the entire life of the loan, typically 30 years or 15 years. Your principal and interest payment stays exactly the same from your first payment to your last. If rates go up, you are protected. If rates go down, you stay at the same amount until you refinance.

The beauty of a fixed rate is predictability. You can build your budget around a payment that will not change, even as life throws you surprises.

What Is an Adjustable-Rate Mortgage (ARM)?

An adjustable-rate mortgage, or ARM, starts with a fixed rate for an initial period, then adjusts on a set schedule. You will see names like 5/1 or 7/1: the first number is how many years the rate stays fixed, and the second is how often it adjusts after that, usually once a year.

The initial rate on an ARM is typically lower than a fixed rate, which means a smaller payment in the early years. After the fixed period ends, the rate moves with the market, up or down, within limits called caps.

Where Mortgage Rates Stand Right Now

As of late September 2026, the national average for a 30-year fixed-rate mortgage is about 7.0%, according to Freddie Mac's weekly survey for the week ending September 24. Buyers here in California are commonly quoted around 7.1%. That is up from about 6.7% a month earlier and roughly three-quarters of a point higher than a year ago.

Adjustable-rate loans are carrying lower starting rates right now: five-year ARMs have been quoted around 6.2% and seven-year ARMs around 6.75%. That lower starting rate is the whole appeal in a high-rate environment.

Here is what that difference means in dollars. On a $700,000 loan, a 7.0% fixed rate works out to roughly $4,650 a month for principal and interest. The same loan around 6.25% comes to about $4,310 a month, a savings of roughly $340 a month.

How First-Time Buyers Should Think About It in West Covina and the San Gabriel Valley

Let's ground this in our own backyard. The median home price in West Covina is around $839,000, down about 3% from a year ago. Homes are taking roughly 36 days to sell, and most sellers receive around two offers. That is a more balanced market than a few years ago, so you have room to ask questions and keep your contingencies without the pressure of a bidding war.

Your timeline matters most. If you expect to stay in the home for seven years or more, a fixed rate protects you for the long haul, and with rates near 7%, locking in certainty can feel like a fair trade. If you know your job, your family, or your next chapter might move you within five to seven years, an ARM's lower starting payment can free up cash while you own the home, and you may never see an adjustment at all.

Questions Every First-Time Buyer Should Ask About an ARM

If you are considering an ARM, do not let the low starting rate do the talking. Ask these questions and write down the answers:

• How much could my payment increase at the very first adjustment?
• What is the lifetime cap, the highest my rate could ever go?
• What index is the loan tied to, and how has it moved in recent years?
• What would my payment look like at the worst-case rate?
• What happens if I need to sell right when the adjustable period begins?

An ARM can work beautifully when you understand how high the payment can go and you are comfortable with that ceiling. It becomes a trap when buyers only hear the low number at the start. I never want that surprise to happen to you.

Let's Have a Conversation

You already have enough to think about without deciphering rate charts alone. Since 1988 I have helped hundreds of first-time buyers across the San Gabriel Valley understand their options, and I wrote a book called "Simplifying Your First Home Purchase" to put this guidance in plain language. If we work together, a copy is yours, free.

And here is something that matters to me personally: when you buy or sell a home with me, you also receive a complimentary Living Trust. The home you are working so hard to buy deserves to be protected for the people you love from day one.

If you are wondering which loan fits your situation, let's have a conversation. No pressure, no jargon, just a straight answer from someone who cares about your next chapter. I'm here to help you, and I will be here for your family long after the keys are in your hand.
