Your 3% Mortgage Is Amazing. But Is It Keeping You in the Wrong House?

I understand why homeowners don't want to give up their 3% mortgage.

I wouldn't want to either.

Prefer to watch instead of read?

I break down the 3% mortgage dilemma, why your equity matters just as much as your interest rate, and how I think about the decision to stay or move in the video below.

As of September 3, 2026, the average 30-year fixed mortgage rate was 6.71%, according to Freddie Mac's Primary Mortgage Market Survey.

So if you bought or refinanced a few years ago and you're sitting on a mortgage somewhere around 3%, selling your house can feel financially ridiculous.

But I've been thinking about the way homeowners make this comparison, because I think we're sometimes comparing the wrong numbers.

We compare 3% versus 6.71%.

Of course 3% wins.

That's not really the question.

The question is: What does your entire financial picture look like if you stay versus if you move?

Let's say you bought your Long Beach house years ago for $700,000. Today, maybe it's worth $1.2 million. I'm deliberately using hypothetical numbers here because every house and mortgage is different.

You may have a fantastic interest rate, but you may also have hundreds of thousands of dollars in equity.

Now let's say the house doesn't work anymore.

You've had another child. You need an office. You want a bigger yard. You want to be closer to the water. You're thinking about Seal Beach or Huntington Beach. Or maybe you've reached the opposite stage and you're maintaining far more house than you actually want.

If we only look at your mortgage rate, the answer is easy:

Stay forever.

But what if you sold?

How much would you actually walk away with after paying off the mortgage and the costs associated with selling?

How much of that equity could go into the next property?

And after applying that equity, how much would you actually need to borrow?

That's the number I care about.

Because you're not necessarily replacing your original mortgage with another mortgage of the same size at twice the rate.

You might be moving a substantial amount of accumulated equity into the next property and financing a very different amount.

Now, that absolutely does not mean moving automatically makes financial sense.

Sometimes we run the numbers and the answer is obvious: keep that mortgage.

Maybe we renovate instead.

Maybe we add square footage.

Maybe we decide the compromises in the current house are worth making because the financial advantage of staying is enormous.

Or maybe we explore whether keeping the current property and buying another one is remotely feasible.

But sometimes the calculation surprises people.

There is also something else that doesn't show up on an interest-rate chart.

What is the house preventing you from doing?

If your family is squeezed into a house you've outgrown for another five years waiting for rates to return to some magical number, there's a cost to that too.

If you're commuting farther than you want, there's a cost.

If you're spending $200,000 trying to turn a house into something it fundamentally cannot become, there's a cost.

And if you've been saying, “We'll move when rates come down,” there's another problem.

What happens if rates eventually do drop substantially?

You probably won't be the only person who notices.

Lower borrowing costs can bring more buyers back into the market, which can change competition and potentially prices. Nobody can promise exactly what rates, prices or buyer demand will do next, which is precisely why I don't love building an entire real estate strategy around predicting them.

Right now, buyers actually have something we haven't always seen in Southern California: more time and more choices in parts of the market.

For example, recent Orange County data showed roughly 5,083 active listings and a median 45 days on market, with the $1 million to $2 million segment at about 40 median days.

That doesn't mean every seller is desperate or every property is negotiable.

It means the environment is different from the frenzy where buyers were fighting over practically anything with a front door.

So if you own a home with a 3% mortgage and you're thinking about moving, I don't think the first question should be:

“Why would I ever give up this rate?”

I'd ask:

“What do I have now, what would I have after selling, what would the next move actually cost me, and is what I gain worth the difference?”

Your 3% mortgage is incredibly valuable.

Just don't accidentally turn it into a pair of golden handcuffs.

Wondering What the Numbers Look Like for You?

If you’ve been thinking about moving but your current mortgage rate is keeping you stuck, let’s actually run the numbers.

We can look at what your home could sell for, what you might walk away with, what your next purchase could look like, and whether moving makes sense at all.

Sometimes the smartest move is to sell. Sometimes it’s to stay. I’d rather help you figure out which one makes sense for you.

That’s exactly why I wrote Make Your Move. Your mortgage rate is important, but it’s only one piece of the decision. The bigger question is what you own today, what you want next, and which option makes the most sense financially and for your life.

The book walks through the choices homeowners often overlook, including staying and renovating, selling and moving up or downsizing, keeping your current home as an investment, tapping into your equity, or simply deciding that now isn’t the right time to do anything.

Thinking about your next move? Let’s talk.
