You probably shouldn't rush to pay off your mortgage.
I know. That's a loaded sentence. Especially coming from someone who spent over a decade teaching Financial Peace University.
I've sat across from hundreds of families in Gilbert, Chandler, Mesa, and Tempe walking through debt, discipline, and the desire for financial peace. I understand the appeal of a paid-off home better than most.
And honestly? It is a big deal.
There's something powerful about owning your home outright. No payment. No bank. Just freedom. It feels safe. It feels responsible. It feels like you've made it.
Dave Ramsey has a line that captures this perfectly.
"The paid-off home mortgage has taken the place of the BMW as the status symbol of choice."
Dave Ramsey
He's right. And I get it.
But here's the tension that keeps coming up in our office.
Just because something feels good doesn't mean it's the best financial decision for your family.
Should I Pay Off My Mortgage or Invest the Difference?
This is one of the most common questions we hear at Stewardship. It shows up in a dozen forms.
- Should I pay off my mortgage early or invest?
- Should I pay cash for a house or get a loan and invest the difference?
- Is it better to put extra money toward principal or into the market?
The honest answer is: it depends. But not as much as most people think. The math usually points in one direction. And the behavior side of it is what makes the real difference.
For most families in the East Valley, keeping a low-to-moderate mortgage and investing the difference will build more wealth over time. But the right answer for your life depends on a few key variables — and one big behavioral question.
The Math: Mortgage Rate vs. Investment Return
Let's simplify it. If your mortgage rate is 6 percent and you can reasonably expect 8 to 10 percent annually in a diversified investment account, the math leans toward investing.
Why? Because your money is working harder invested than it is eliminating a relatively low-cost loan. Over long periods of time, that gap compounds.
Here's a real example. Say you have $300,000 and you're deciding what to do with it.
Invest at 8% for 25 years
$2.05M
$300,000 invested in a diversified portfolio compounding annually at 8% over 25 years.
Pay off 6% mortgage instead
$300K
You eliminate $300,000 of 6% debt. Equity is real — but it doesn't compound the same way.
That's not a rounding error. That's generational. That 2-percent gap between your mortgage rate and a reasonable market return, compounded over decades, is one of the most powerful forces in personal finance.
This is why, mathematically, most people are better off keeping their mortgage and investing the difference.
But Math Isn't Everything
Here's where most financial advice falls short. Personal finance is not just math. It's behavior. And behavior drives outcomes more than spreadsheets ever will.
If having a mortgage keeps you up at night, causes stress in your marriage, or makes you feel like you're constantly behind — then the "better math" might not actually be better for you.
I've seen people with perfect financial plans sabotage themselves because they didn't have peace. And I've seen people with suboptimal math build incredible wealth because they were consistent, disciplined, and confident.
Pride is a terrible financial advisor. Wisdom is a much better one.
Paying off your house for the badge — the way people buy BMWs for the badge — is not a strategy. It's a feeling. And major financial decisions should not be driven by feelings alone.
5 Variables That Should Guide Your Decision
Before you decide, run it through these five lenses. They're the same ones we walk through with every family that sits down with us.
Your Mortgage Interest Rate
This is the most important number. A 3% mortgage in a historically normal market is almost always worth keeping. A 7.5% mortgage starts to shift the conversation. The lower the rate, the more powerful the case for investing.
Your Time Horizon
The longer your runway, the more powerful compounding becomes. A 35-year-old with 30 years ahead is in a fundamentally different position than someone 5 years from retirement. Time is the biggest variable of all.
Your Expected Investment Return
We don't control the market. But we can make reasonable long-term assumptions. The S&P 500 has averaged roughly 10% annually over the last 50 years before inflation. Assuming 7–9% net is conservative and defensible. Your actual return depends on your account type, diversification, and time in market.
Will You Actually Invest the Difference?
This is the behavioral question that changes everything. If you keep the mortgage but don't invest the extra cash — if it just disappears into lifestyle spending — you've gotten neither the peace of a paid-off home nor the growth of investing. Discipline is the multiplier.
Your Mental and Emotional Well-Being
Peace matters. If the mortgage is genuinely damaging your marriage or keeping you in chronic financial anxiety, that's a real cost — one the spreadsheet doesn't capture. A slightly suboptimal financial strategy that you can actually live in is better than a perfect plan you can't execute.

Your Numbers
Investing keeps your money accessible. Paying down your mortgage locks it in your home — you can't spend equity without a loan or a sale.

The Factor Nobody Talks About: Liquidity
Here's an angle that almost never gets covered in the pay-off-your-mortgage conversation. And it matters a lot.
When you put extra money toward your mortgage, it becomes home equity. And home equity is not liquid cash.
You can't call your mortgage company on a Tuesday and ask for $40,000 back. You can't use your equity to cover a job loss or a medical bill without applying for a HELOC, doing a cash-out refinance, or selling the house. All of those options take time, cost money, and depend on lender approval — which is not guaranteed.
When you invest that same money, it stays accessible. You can sell investments. You can draw from a taxable brokerage account. In an emergency, that liquidity is worth something real.
Based on $500/mo extra, 8% annual return, 6.5% mortgage rate, 25 years. Hypothetical illustration only.
For the first 17 years of this scenario, the pay-down strategy has $0 in accessible cash. Every dollar is locked in home equity.
That's not inherently wrong. Equity is real wealth. But it changes how you navigate an emergency, a job transition, an opportunity, or a kid's college tuition. Flexibility has value. Most people just don't price it in until they need it.
Should I Pay Cash for a House or Get a Mortgage?
This is the same conversation, just at the front end of the decision.
If you have the ability to pay cash for a home, you're essentially asking: should I tie up all this money in my house — or keep a mortgage and invest the difference?
Again, math usually points one direction. Keep liquidity. Get a mortgage. Invest the difference. You maintain flexibility, keep your money working, and avoid being house rich and cash poor.
But again — if carrying a mortgage would cause you to make worse financial decisions overall, that matters. The right strategy is the one you can actually live in with peace and consistency.
My Take
If we're talking strictly math, most people should keep the mortgage and invest the difference.
But if we're talking about your life — your stress level, your marriage, your habits, your discipline, your peace — then the right answer might be different.
Math matters. Behavior matters more. And sometimes the best financial decision is the one that helps you live with clarity, consistency, and confidence.
That's what we want for you. And if you want to walk through your specific situation with someone who will look at the full picture — not just the math — that's exactly what we do at Stewardship.
Frequently Asked Questions
Should I pay off my mortgage early or invest the extra money?
For most people in Gilbert, Chandler, Mesa, and the East Valley, investing the extra money will build more total wealth over time — especially if your mortgage rate is below 7%. The math favors investing when your expected market return exceeds your loan rate. That said, if carrying a mortgage creates significant stress or you don't trust yourself to actually invest the difference, paying down the mortgage may be the better behavioral decision even if it's not the mathematically optimal one.
What does Dave Ramsey say about paying off your mortgage?
Dave Ramsey famously said "the paid-off home mortgage has taken the place of the BMW as the status symbol of choice," and he strongly advocates for paying off your mortgage as part of his Baby Steps plan. His approach prioritizes peace and behavioral simplicity over mathematical optimization. Many financial advisors — including our team at Stewardship — respect the behavioral wisdom in that approach while noting that the math typically favors investing the difference, especially for those with low mortgage rates and long time horizons.
Should I pay cash for a house or get a mortgage and invest the difference in Arizona?
In most cases, getting a mortgage and investing the difference will produce greater long-term wealth than paying cash — especially in Arizona's current rate environment. When you pay cash, your money is locked in home equity and stops compounding. When you keep a mortgage and invest, your money keeps working. The key exception is if carrying debt creates enough stress or behavioral risk that it leads to worse financial decisions overall. A Stewardship advisor can help you run your specific numbers in Gilbert, Chandler, Mesa, Tempe, or Queen Creek.
At what mortgage rate does it make more sense to pay off the loan instead of investing?
There's no single break-even rate that works for everyone, but as a general rule, a mortgage rate above 7–8% starts to make the "pay off the loan" case more compelling — because you're now competing with expected market returns rather than beating them. At rates below 6%, the math almost always favors investing. Between 6% and 8%, the right answer depends on your specific situation, your investment account type, your tax rate, and your time horizon. Our free calculator at the top of this page lets you plug in your exact numbers.
Is home equity liquid? Can I access my equity if I need cash?
No — home equity is not liquid cash. You cannot access equity without selling your home, taking out a HELOC (Home Equity Line of Credit), or doing a cash-out refinance. Each of those options takes time, involves lender approval, costs money, and is not guaranteed. This is one of the most overlooked factors in the pay-off-mortgage vs. invest decision. Money invested in a brokerage or retirement account is far more accessible in an emergency. A Stewardship advisor can help you weigh the liquidity tradeoff as part of your full financial picture.
