One of the most common questions I hear from clients approaching retirement is also one of the most emotionally loaded: “Should I pay off my mortgage before I stop working?”
The honest answer is: Sometimes.
That’s not a cop-out. It’s the only answer that respects both sides of this decision.

Paying off a mortgage is not just a math problem. It’s a cash-flow problem, a tax problem, an investment problem — and, for a lot of people, a peace-of-mind problem.
The mistake is assuming there’s one universal rule. There isn’t. The right answer for a homeowner carrying a 2.875% mortgage, a solid brokerage account and a reliable pension looks very different from the one facing someone with a 6.5% loan heading into heavy IRA withdrawals.
Two recent changes make the math worth revisiting.
- Freddie Mac’s weekly survey puts the average 30-year fixed rate at 6.51% as of late May 2026.
- The SALT deduction cap increased to $40,000 under the One Big Beautiful Bill Act, with phaseouts starting above $500,000 in modified adjusted gross income.
Both shift the calculus for retirees in ways that weren’t in play two years ago.
Start with where you are in your mortgage
By the time most clients ask this question, they’re in the last quarter or third of their loans. That matters more than people realize.
Early in a mortgage, your payment is mostly interest. Later, it flips — you’re paying far more principal than interest. The amount of interest you’d avoid by paying off early is probably smaller than you expect.
Here’s a concrete example. Take a married couple with an original $350,000 mortgage at 6.5% and $111,000 still owed at year 26. Their annual payment runs about $26,547, but only $6,767 of that is interest. The total interest remaining in the next four years is roughly $19,670.
Compare that with the cost of paying off the loan by pulling from retirement accounts. Assuming a 24% federal bracket and 5% state tax, they’d need to withdraw approximately $140,845 to net the $111,000 after taxes, generating about $7,042 in state taxes and $33,802 in federal taxes.
That’s more than $40,000 in taxes to eliminate $19,670 in interest. The numbers don’t hold up.
The SALT change and why your state tax burden matters
For years, the $10,000 SALT cap made itemizing difficult for most homeowners. The new $40,000 limit changes that, particularly in higher-tax states such as Connecticut, New York or California.
At our firm, a large share of clients come from Connecticut, and this is the kind of question in which having accountants on staff pays off. The answer depends on whether you’re itemizing, which depends on your full tax picture.
If you can now itemize under the new cap, your mortgage interest carries more federal tax value. That doesn’t automatically mean you should keep the mortgage. It means you should compare your mortgage rate with your investment returns on an after-tax basis, not gross.
Don’t drain your liquidity to feel debt-free
This is where a spreadsheet can mislead you.
Say you owe $300,000 and have $350,000 in taxable savings. Paying off the loan might feel like the right move. But if it leaves you with $50,000 outside your retirement accounts, you’ve traded one risk for another.
Retirees need accessible cash for home repairs, health costs, long-term care planning, tax bills, and market downturns. If paying off the mortgage means pulling more aggressively from IRAs later, you could end up with higher taxable income, steeper Medicare premiums and more of your Social Security subject to tax.
A paid-off house is comforting. But you can’t spend your kitchen.
A practical framework for making the call
If your mortgage rate is below 4%, you’re taking the standard deduction, and your portfolio is diversified, keeping the mortgage often makes more financial sense.
If your rate is above 6%, you get little or no tax benefit from the interest deduction, and if you have enough liquid assets remaining after payoff, paying it down becomes more compelling.
If you’re somewhere in between, run four numbers before deciding:
- The after-tax cost of your mortgage (not the stated rate)
- Realistic after-tax portfolio return expectations
- Remaining liquidity after payoff
- The tax bill from withdrawing retirement funds to make the payoff
The real answer isn’t “always pay it off” or “always stay invested.” It’s: Pay it off when the numbers work, your cash reserves stay healthy, and the peace-of-mind benefit is genuinely worth what you might be giving up.
Sometimes it is. And sometimes the spreadsheet makes that clear before your gut does.
