Pay Off the Mortgage Before Retirement? The Math and the Pillow Test

This article draws on Michael Kitces’s writing at Kitces.com on mortgages and leverage (2011, 2012, 2013, 2015, and 2016), on Adam Van Deusen’s 2023 article there on mortgage decisions when rates are higher, and on Derek Tharp’s 2018 summary of research by Abigail Sussman and Eldar Shafir. We’d recommend reading them in full. The examples, figures, and arithmetic below are our own.

Few financial questions come with as much feeling attached as this one. For some households a paid-off home is the finish line that makes retirement feel real. For others the mortgage is the cheapest money they will ever borrow, and paying it off early feels like handing back a gift. Both instincts have something right in them, and neither one is a plan. The decision turns on four things that differ for every household: the interest rate, the liquidity left afterward, the taxes on the money used, and what the invested dollars can reasonably be expected to earn.

What a Payoff Actually Earns

Every extra dollar sent to the mortgage stops owing interest at the loan’s rate. That is the whole return, and it is as close to guaranteed as a household gets. A dollar that retires 3.25% debt earns 3.25%. A dollar that retires 6.75% debt earns 6.75%. On a fixed-rate loan, nothing about the stock market, the housing market, or inflation changes that number.

Michael Kitces made the point in 2012 that this makes the mortgage rate the borrower’s own risk-free rate. An investor who owes nothing compares stocks with government bonds. A household with a mortgage has a second safe choice, which is to pay the loan down, and that choice sets the bar every other use of the money has to clear. We call it the hurdle rate.

The tax deduction rarely changes the hurdle. Mortgage interest is deductible only for households that itemize, on up to $750,000 of debt used to buy, build, or improve the home ($1,000,000 for loans taken out before December 16, 2017), a limit the 2025 tax law made permanent. For 2026 a married couple who are both 65 or older has a standard deduction of $35,500, before the separate senior deduction. A retired couple with a modest balance seldom has enough interest, property tax, and charitable gifts to exceed that, so the interest saves them nothing and the hurdle is the full loan rate.

The safe alternative is taxed. Interest on Treasury bonds is taxed by the federal government (and exempt from state income tax, which matters outside Texas). With the 10-year Treasury yielding about 4.9% in early November 2026, a couple in the 12% bracket keeps about 4.31% and a couple in the 22% bracket keeps about 3.82%.

Put those together and the answer splits by loan, a point Adam Van Deusen made in 2023 when safe yields first climbed above older mortgage rates. Against a 3.25% mortgage, a safe bond wins after tax: 4.31% beats 3.25%. Against a 6.75% mortgage, nothing safe comes close. A couple in the 12% bracket would need a safe investment yielding about 7.67% before tax to match the payoff, and none exists.

For money held in safe bonds, the edge on a cheap loan is real, and small. A household that keeps a $240,000 balance at 3.25% and holds the same amount in Treasuries at 4.9% comes out ahead by about 1.06 points after tax in the 12% bracket, or about $2,500 a year. In the 22% bracket the edge is about $1,400 a year. That is worth having. It is also modest next to how strongly people argue about it, it is locked in only for as long as the bond runs (money kept in shorter-term savings loses it whenever yields fall below the loan rate), and it exists only if the money really sits in the safe investment.

Keeping the Mortgage to Stay Invested

Most households that keep a mortgage are not holding Treasuries against it. They are holding stocks, and that is a different decision. Kitces observed in 2011 that keeping a mortgage in order to stay invested puts the household’s balance sheet in the same position as borrowing to invest. Adam Van Deusen made the companion point in 2023: many people who would be uncomfortable borrowing against a paid-off house to buy stocks are comfortable keeping a mortgage and a stock portfolio side by side, although the two balance sheets look much alike.

That does not make keeping the mortgage wrong. It means the fair test is not whether stocks are expected to beat the loan rate. They usually are expected to. The test, in Kitces’s 2012 framing, is whether they are expected to beat it by enough to pay for the risk. In our data from 1934 through June 2023, stocks earned about 7.0% a year after inflation and a constant 10-year Treasury bond about 1.2%. That gap is what investors have been paid, on average and over long stretches, for living through the declines. With a 3.25% loan, the rate sits below what safe bonds pay today, so a household that stays invested keeps the full premium that stocks have earned over bonds. With a 6.75% loan, the rate sits well above the bond yield, and the margin left to pay for the risk is noticeably thinner. Averages also take a long time to show up, and a mortgage with 10 or 15 years left does not offer a long time.

What a balanced portfolio has actually done. Few retirees hold only Treasuries or only stocks, so the fairer comparison is with a balanced portfolio. We ran two generic mixes, one with 60% in stocks and 40% in bonds and one with 70% and 30%, through every 15-year period in our data that began between 1871 and mid-2008: 1,650 periods, starting a month apart. Across the whole stretch the 60/40 mix earned about 7.6% a year and the 70/30 mix about 8.0%. The 15-year results spread widely around those averages. For the 60/40 mix the middle period earned about 7.0% a year, a weak one (the 10th percentile) about 4.9%, and a strong one (the 90th) about 11.3%, with a worst of about 2.0% and a best of about 16.4%. For the 70/30 mix the same figures were about 7.3%, 4.9%, and 12.5%, with a worst of about 1.5% and a best of about 17.1%.

Set the two loans against that history and they tell different stories. The 60/40 mix out-earned a 3.25% loan in about 98% of those periods and the 70/30 mix in about 97%. Against a 6.75% loan the 60/40 mix came out ahead in about 54% of periods, close to a coin flip, and the 70/30 mix in about 59%. The mix with more stocks cleared the higher bar more often and also had the wider range, including on the low end.

Four cautions belong next to those numbers. They are hypothetical results from historical index data, before inflation, taxes, and fees, for textbook mixes; they are not our strategy, any client account, or a prediction, and every point of cost or tax raises the bar a portfolio has to clear. The periods overlap heavily, so 1,650 of them hold only about ten separate 15-year stretches, and the percentages describe how often something happened along one historical path, not the odds going forward. The weak periods cluster: the worst ones for both mixes began just before the 1929 crash, and the strongest began in the early 1980s, when mortgages cost far more than 6.75%, so that end of the chart was never on offer against a loan at today’s rates. And a yearly return above the loan’s rate is not quite the same as coming out ahead. A mortgage charges interest monthly, so a 6.75% loan costs about 6.96% a year, and a household that pays the mortgage from the invested money draws it down month by month, which makes the early years count for more. Run that way, with $240,000 invested and each payment on a 15-year loan taken out of the portfolio, the 60/40 mix finished ahead in about 94% of periods at 3.25% and about 49% at 6.75%, and the 70/30 mix in about 93% and 53%. A later section builds on that version.

That is both sides of the decision in one picture. At a low rate, history leans heavily toward keeping the loan and staying invested, and the price is living through the declines along the way. At a high rate, the certain return of a payoff has matched or beaten the uncertain one about as often as not. And no household gets the average. It gets one particular stretch of years, and nobody knows in advance which one.

The mortgage is not the inflation hedge. A fixed payment does get easier to carry as prices and incomes rise. Kitces showed in 2015 that the protection comes from what the borrowed money is invested in and from the income that pays the loan, not from the loan itself. We cover what does defend a retirement against rising prices in our article on inflation in retirement.

The Payment Is a Fixed Withdrawal

Retirement changes the question in one important way. A working household pays the mortgage from a paycheck. A retired household pays it from the portfolio, every month, whether markets are up or down.

Take a hypothetical couple, Ray and Elena, both 66 and retired in the San Antonio area. They have $2,000,000 saved, most of it in traditional IRAs, and they draw $100,000 a year from it, a withdrawal rate of 5.0%. Their mortgage has a $240,000 balance at 3.25% with 15 years left, and the principal and interest payment is $1,686 a month, or $20,237 a year.

Divide the yearly payment by the balance and the result is 8.4%. Call that the loan’s payment rate. It measures cash flow, not return: how much cash the loan demands each year for every dollar it would take to retire it, and here the loan demands cash much faster than the plan as a whole draws on savings. If Ray and Elena retired the loan from their brokerage account, their yearly draw would fall to $79,763 on about $1,755,000, a withdrawal rate of about 4.5%.

The relief is front-loaded, because the payments would have ended in 15 years anyway. That timing matters. The first decade of retirement is when a poor run of markets does the most damage, a pattern we explain in our article on sequence-of-returns risk. Kitces noted in 2013 that an amortizing mortgage adds to that risk, since its payments keep coming out of a portfolio that may be down. A plan built on spending guardrails handles a decline by trimming spending by a few percent, held only until the plan recovers, and a mortgage payment is spending that cannot be trimmed. The shorter the time left on a loan, the higher its payment rate, and the more a payoff frees.

Where the Money Comes From Decides Most of the Cost

A payoff is only as good as its funding. The same $240,000 can cost a few thousand dollars in tax or the price of a new car, depending on which account it leaves.

Ray and Elena draw their $100,000 from their IRAs and have not yet claimed Social Security. On 2026 figures their federal tax is $5,804, and their income sits well inside the 12% bracket. We priced several ways for them to retire the mortgage, each one sized so that $240,000 reaches the lender after tax.

From the brokerage account. They sell $244,816 of investments, of which 30%, or $73,445, is long-term gain. Because their ordinary income leaves room under the 0% capital gains ceiling, $43,587 of the gain is taxed at 0% and $29,858 at 15%. With a small loss of the senior deduction, the added federal tax is $4,816. A household with a recent inheritance or the proceeds of a sale often holds assets with almost no gain, and for them the cost can be close to nothing. A low-basis position is a different story. If 80% of the sale were gain, the same payoff would take a $271,398 sale and cost $37,168: $31,398 of added tax, including $2,551 of the 3.8% net investment income tax, plus $5,770 of Medicare surcharges two years later. (How that 0% space works is in our article on the 0% capital gains bracket.)

From a Roth account. A qualified Roth withdrawal adds nothing to taxable income, so it funds a payoff with no tax and no Medicare surcharge. The cost is the account’s future tax-free growth, which is often among the most valuable growth a household owns, so a Roth belongs in the same comparison as every other source.

From the IRA in one year. Every dollar is ordinary income, so they must withdraw $309,042 to net $240,000. Their income passes $409,000. The withdrawal runs through the 22% bracket into the 24% bracket, their $12,000 senior deduction disappears, and the added federal tax is $69,042. Two years later that income sets their Medicare premiums: both land in the bracket that begins at $342,001 of income, which adds $9,240 of surcharges for the year. They are less than $1,000 below the next bracket, which begins at $410,001 and would add about $3,500 more, and the example assumes no other income. The total is $78,282, equal to almost a third of the balance they set out to retire and about a quarter of the withdrawal. (Our IRMAA article explains the two-year lookback.)

From the IRA across two tax years. Half is withdrawn in November and half in January. The loan is gone within a couple of months, apart from a few hundred dollars of interest on the half that waits, but the income lands on two returns. (Tax withheld from an IRA withdrawal is treated as paid evenly through the year, so withholding enough from each one can avoid an underpayment penalty on a large late-year distribution.) Each year’s extra withdrawal is $151,147, the added tax is $31,147 a year, and the Medicare surcharge is $2,297 a year in the lowest tier. The total is $66,888, about $11,400 less than doing it all at once.

From the IRA across three or four tax years. Stretching further keeps their income below the first Medicare threshold of $218,000 and preserves part of the senior deduction. The total falls to $53,989 over three years and $45,828 over four. The cost of waiting is interest on the balance that remains. At 3.25% that is a small price for the tax saved. At 6.75% it is not small, and the comparison has to be run both ways.

The IRA figures use 2026 brackets, deductions, and Medicare surcharge amounts for every year, as a stand-in for years whose figures are not yet published, and the senior deduction is scheduled to end after 2028, so the later years of a three- or four-year schedule will not match these figures exactly. They are federal amounts for a hypothetical couple. A household already receiving Social Security faces one more layer, because IRA withdrawals can pull more of the benefit into taxable income, a pattern we explain in our article on the Social Security tax torpedo.

One point runs through all of them. An IRA withdrawal is not a loss just because it is taxed. Those dollars will generally be taxed someday, either in the owner’s hands or in the heirs’, unless they go to charity. What makes a large one-year withdrawal expensive is paying 22% and 24% on dollars that, on this couple’s current path, would likely have come out at about 12%, and triggering surcharges that a slower pace would have avoided. At 12%, the same $309,042 would carry about $37,100 of tax, so roughly $41,200 of the $78,282 is the price of doing it all at once.

The brackets show why. In the one-year plan the couple adds $321,042 of taxable income (the withdrawal plus the $12,000 senior deduction it eliminates): $48,300 fills the rest of the 12% bracket, $110,600 fills the whole 22% bracket, and $162,142 lands at 24%. Split across two tax years, each year still fills the 12% and 22% brackets, but only $4,247 reaches 24%. Spread across four, each year adds $48,300 at 12% and $25,732 at 22%, and nothing reaches 24%.

A household already in the 22% bracket gets a different lesson. Give the same couple $180,000 of IRA income instead of $100,000. Their taxable income is $136,100, inside the 22% bracket. A one-year payoff now takes a $323,215 withdrawal and costs $95,925 in added tax and Medicare surcharges, with $64,165 of the added income reaching the 32% bracket. That is a bigger bill than the first couple’s, but about $71,100 of it is tax those dollars would have owed at 22% anyway (more while the senior deduction phaseout lasts), so the price of doing it all at once is about $24,800 at most, not $41,200. Spreading helps them far less: two tax years cost $88,671 and four cost $87,661, because they lose the senior deduction and land in a Medicare surcharge tier in every year either way. Three tax years cost $95,111, more than two, because that pace pays the same surcharge tier in three years instead of two. Slower is not automatically cheaper, which is why each schedule gets priced.

Timing matters as much as pace. A household still drawing a paycheck in the 24% or 32% bracket pays more for every IRA dollar than it likely will in the first years of retirement, before Social Security and required distributions begin. Those low-income years are the least expensive window for a payoff that has to come from pre-tax money, and they are the same years our article on the retirement gap years describes for Roth conversions. The bracket room a payoff uses is also the room a household might otherwise fill with Roth conversions, so the two belong in the same projection.

Putting the History and the Taxes Together

The two halves of this article belong in one model, because a household that keeps its mortgage does not just earn a return. It also makes the payments, and it keeps the money a payoff would have cost, including the tax.

So we ran the history again with the cash flows in it. In each of the same 1,650 periods, the money a payoff would have used stays in the portfolio, each monthly payment on a 15-year loan comes out of it, and keeping the loan comes out ahead if anything is left when the loan is gone. With no tax counted, $240,000 stays invested, and a 60/40 mix came out ahead in about 94% of periods against a 3.25% loan and about 49% against a 6.75% loan (about 93% and 53% for the 70/30 mix).

Now count the tax. If the payoff would have come from the brokerage account, $244,816 stays invested, and the 60/40 figures barely move: about 96% and 53%. If it would have come from the first couple’s IRA in one year, $309,042 stays invested, the avoided Medicare surcharges stay too, and each payment is drawn from the IRA at their 12% rate. Keeping the loan then came out ahead in about 99% of periods at 3.25% and about 84% at 6.75%. Split across two tax years, the figures were about 98% and 75%. For the couple in the 22% bracket, whose lump sum costs less beyond what they would owe anyway, the 3.25% figures were about 97% to 98%, and the 6.75% figures were about 62% to 72% in one year and about 56% to 64% across two. The range is there because their payments would come out of the IRA at 22% in the long run but at about 24.6% while the senior deduction phaseout lasts, and the answer is sensitive to which rate is used.

Where the money comes from changes the comparison, not just the cost. At 6.75%, a payoff funded from a brokerage account came out ahead about half the time in that history. The same payoff funded from an IRA in one year came out behind in about five periods in six for the first couple, because it takes $309,042 of IRA money to retire $240,000 of debt, and the difference keeps working if the loan is kept.

Costs on the portfolio pull the other way. Every figure above is before fees and before taxes on the portfolio’s own income. With a cost of half a point a year taken out of the 60/40 mix, the no-tax figures fall from about 94% and 49% to about 90% and 43%. With a full point, roughly the size of an advisory fee or a meaningful tax drag, they fall to about 85% and 38%. A higher-cost portfolio has to clear a higher bar, which is as true of the ones we manage as of any other.

The cautions from the history section apply here in full. These are hypothetical results from overlapping periods of one historical path, for generic mixes. The test also counts a one-dollar surplus the same as a large one and says nothing about the size of a shortfall. And the IRA figures assume every future payment would have come out at the household’s current bracket: required distributions, Social Security, or a surviving spouse’s single brackets would raise that rate and pull those figures down. They are a way to see how the pieces interact, not a forecast.

Recasting and the Other Moves Between All and Nothing

The choice is rarely between paying off everything and paying off nothing.

Recasting is the move many people have not considered. After a lump-sum payment toward principal, many lenders will re-amortize the remaining balance over the remaining term for a modest fee, which lowers the required payment. Kitces pointed out in 2016 why this matters: the reward for an ordinary prepayment arrives years later, when the loan ends early, while a recast shows up in the next month’s bill. The comparison below follows his, with our own numbers. Suppose the same $240,000 balance were a newer loan at 6.75% with 25 years left and a payment of $1,658 a month. A $100,000 prepayment with no recast leaves the payment where it was and pays the loan off in about 9.6 years, saving about $207,000 of interest. The same prepayment with a recast drops the required payment to $967, a cut of $691 a month, and still saves about $107,300 of interest if the couple pays only the new minimum. They can keep paying the old amount if they like. The recast gives them the choice, which is worth the most in exactly the year when cash is tight. Conventional loans can often be recast, while FHA and VA loans generally cannot, and some servicers require a minimum lump sum, so it is a question for the loan servicer.

A target balance can do most of the work. Paying the loan down to a level the household is comfortable carrying, then recasting, often captures much of the cash flow relief at a fraction of the tax cost of a full payoff from an IRA.

Extra principal each month is the slow version. It needs no lump sum and no tax event, and it suits a household still working that wants the loan gone by a retirement date.

Refinancing is sometimes the answer. When rates have fallen meaningfully below the loan’s rate, a refinance can lower the hurdle more cheaply than a payoff can remove it. Closing costs and the years left on the loan decide whether it pays.

The home can still be a backstop. A paid-off home is wealth that is hard to spend. A line of credit opened before the paychecks stop, or a reverse mortgage later in life, can make that equity reachable in an emergency, with real costs and limits. We lean toward treating either one as a backstop, and a plan never depends on it. Our article on HELOCs and reverse mortgages in Texas covers the rules and the math, and our article on downsizing in retirement covers the other way to turn a house into spendable money.

Why Paying It Off Feels So Good

The pull toward a paid-off home is not a failure of arithmetic. In experiments by Abigail Sussman and Eldar Shafir, which Derek Tharp summarized at Kitces.com in 2018, people shown two households with identical net worth judged the one with less debt to be better off, as long as net worth was positive. When net worth was negative, they preferred the household with more assets. The studies used hypothetical profiles and, as Tharp noted, still needed to be replicated. Tharp drew the connection to retirement: people who have built real savings often want their debts gone, even when the totals say it makes no difference.

That preference deserves respect and also a second look. A household that empties its accessible savings to retire a 3% loan has traded flexibility for peace of mind. It now owns a larger share of its wealth in one asset that cannot pay for a roof, a medical bill, or a bad year in the markets. Property tax and insurance continue after the last payment, and with no escrow account the household pays them directly. Sleeping well matters. So does being able to reach the money. The two choices are also not symmetrical. A household that keeps the loan can still pay it off next year, or in five years. A household that pays it off can get the money back only by borrowing again, at whatever rate and on whatever terms are available then.

How We Think About It

We have no standing lean on paying off a mortgage before or during retirement. The answer depends on the interest rate, the liquidity the household keeps afterward, the taxes on the money used, and what the invested dollars can reasonably be expected to earn, and those differ for every household.

The first thing we ask is what being mortgage-free would change for you. The answers sort into three kinds. Some people want lower monthly outflow. Some want less risk. Some want the feeling of owning their home outright. Each is a legitimate goal, and each points to a different set of tools, so we want to know which one we are solving for before we run a number.

Then we do the math. We compare the loan’s rate, which is the hurdle, with what safe money earns after tax, as described above, and we run both paths through the household’s plan: the same historical market sequences, the same forward assumptions, and the same spending guardrails, once with the mortgage kept and once with it retired. What we are looking for is what each path lets the family spend and give, and how each holds up in the bad sequences, not which one ends with the larger balance.

A large part of our job on a question like this is showing both sides: what history and reasonable expectations say about the opportunity, adjusted for its risk, and the plain fact that no one knows which way things will go in one family’s situation and timeframe.

On funding, we lean toward taxable accounts first, especially recent cash or investments with little built-in gain. We usually lean away from a large IRA withdrawal because of the tax it sets off. When an IRA is the only source and the payoff still makes sense, we lean toward spreading the withdrawals over two to four tax years, sometimes as simply as November and January, and we price each version against the brackets, the senior deduction, and the Medicare thresholds before choosing. When the money has to come from pre-tax accounts, we lean toward looking first at the low-income years between the last paycheck and the start of Social Security and required distributions, and we size a payoff in the same projection as Roth conversions, since both draw on the same bracket room. Roth dollars go into the same comparison as every other source, with the tax-free growth they would give up counted as a cost.

Last comes what we call the pillow test: math aside, how does carrying the debt, or giving up the liquidity, affect your ability to sleep at night? How much weight that gets depends on how much the math matters. When the decision makes or breaks the plan, the math carries the most weight. When either path lets the family do what is important to them, how they sleep carries real weight. The test only works when it is honest about tradeoffs. “I don’t want a mortgage” is a fine preference, but if a payoff strains the plan, the conversation is no longer about the mortgage alone. It becomes a conversation about which other levers the family is willing to move to make it possible, such as working a little longer, spending a little less, a smaller payoff, or a recast.

The factors do pull in predictable directions. A payoff looks weaker in the numbers when it leaves a household short of accessible savings, or when it is funded at a much higher tax rate than the same dollars would otherwise face. It looks stronger when the loan’s rate is well above what safe money earns, when the funding is cheap, and when the payment is a large fixed draw early in retirement. Which of those carries the day differs from one household to the next, which is why we have no standing lean.

A candid note on our own interest: for the investments we manage, we charge a tiered asset-based fee, so advice to keep a mortgage and stay invested keeps our fee higher and advice to pay the loan off from those accounts lowers it, which is one more reason those decisions belong in numbers rather than impressions.

Common Questions

Is it smart to pay off your mortgage before you retire?

Whether paying off a mortgage before retirement is smart comes down to four things: the loan’s rate against what safe money earns after tax, where the payoff money comes from, how much accessible savings is left afterward, and what the invested dollars can reasonably be expected to earn. A payoff earns exactly the loan’s interest rate with no risk, which is a strong result at 6.75% and a weak one at 3.25% when safe bonds pay more. We have no standing lean. We lean toward modeling both paths in the household’s plan and then weighing how each one affects their peace of mind.

Is it better to pay off the mortgage or invest?

Paying off a mortgage is the better use of a dollar on the math when the loan’s rate is higher than what a safe investment earns after tax, and investing is better when the rate is lower, as long as the money really goes into something safe. Against a balanced portfolio, history gives a split answer: in our index data, before taxes and fees, keeping the loan and staying invested in a 60/40 mix came out ahead in about 94% of 15-year periods against a 3.25% loan and about 49% against a 6.75% loan. The extra return is payment for risk, and a mortgage with 10 or 15 years left does not give averages much time to work. We have no standing lean between the two. We lean toward comparing them inside the household’s own plan.

Should I use my IRA or 401(k) to pay off my mortgage?

A large withdrawal from an IRA or 401(k) is usually the most expensive way to pay off a mortgage, because every dollar is taxed as ordinary income in the year it comes out. In our example, netting $240,000 from an IRA in one year cost a retired couple about $78,300 in added federal tax and Medicare surcharges, compared with about $4,800 from a brokerage account. Some of that IRA tax would have come due eventually, but at lower rates and without the surcharges. When a retirement account is the only source, spreading the withdrawals over two to four tax years can lower the cost substantially. For a household already in the 22% bracket, the penalty for doing it at once is smaller and spreading helps less, so each schedule is worth pricing.

Does it make sense to pay off a mortgage with a 3% rate?

A mortgage near 3% is hard to justify paying off on the math alone when safe bonds yield more than the loan costs after tax. With the 10-year Treasury near 4.9% in early November 2026, a couple in the 12% bracket keeps about 4.31% on a safe bond, which beats a 3.25% loan by about $2,500 a year on a $240,000 balance. Money kept in a balanced portfolio has historically done better still: in our index data, before taxes and fees, keeping a 3.25% loan and staying invested in a 60/40 mix came out ahead in about 94% of 15-year periods. The math leans toward keeping a loan like that, so the reasons to pay it off are the ones beyond the math, such as a lower fixed draw in early retirement or peace of mind.

What is a mortgage recast, and how is it different from refinancing?

A mortgage recast keeps the existing loan and its interest rate and recalculates the payment after a lump-sum payment toward principal, while a refinance replaces the loan with a new one at a new rate. A recast usually costs a modest fee and typically requires no appraisal or new underwriting. In our example, a $100,000 prepayment on a $240,000 balance at 6.75% with 25 years left lowered the required payment from $1,658 to $967 a month. Not every loan can be recast, so it is a question for the loan servicer.

Do I lose a tax deduction if I pay off my mortgage?

Most retirees give up little or nothing in tax deductions by paying off a mortgage, because most no longer itemize. For 2026 a married couple who are both 65 or older has a standard deduction of $35,500, and mortgage interest helps only to the extent that total itemized deductions exceed that amount. A household with a large loan and high property taxes may still itemize, and for them the after-tax cost of the loan is somewhat lower than its stated rate.

Is a mortgage a good hedge against inflation?

A fixed-rate mortgage is not an inflation hedge by itself. The payment does become easier to carry when incomes rise with prices, but that protection comes from the income, or from what the borrowed money is invested in, and a retiree whose income does not rise with prices gets less of it. Keeping a mortgage in order to stay invested is a decision about investing with borrowed money, and it is best judged that way.
