Pros and Cons of Prepaying Mortgage

Whether paying off your mortgage early is a smart strategy depends on a lot of factors. Understand the pros and cons; then learn how to crunch the numbers.

You don’t have to wait out the remaining term of your mortgage to pay it off.

Instead, you can make accelerated payments on an occasional or regular basis, which could save you big money in interest charges overall.

This may be a good strategy if…

  • … your mortgage has a high interest rate and you have extra money in the bank, or…
  • … you want to worry less about debt.

But your mileage may vary.

Your best option may not be to prepay your mortgage. You might earn a higher rate of return by investing that extra cash. It could be wiser to simply refinance if rates drop. And you may regret prepaying if you need more money later for an emergency.

The best course of action is always to explore your options, crunch the numbers, and weigh the plusses and minuses. Making accelerated payments to pay off your mortgage might help you sleep better at night, but it could also leave you more vulnerable to other unforeseen expenses.

Pros & Cons: Should I Prepay My Mortgage?

Weighing the pros and cons of personal finance decisions naturally comes down to the value you place on each of your choices, and that’s why it’s difficult to make blanket statements about which course is better.

It’s a good idea to try different scenarios on a refinance calculator. You can model each option to help you visualize the impact on your finances over the long term – because it can add up to large amounts. Sometimes seeing actual numbers helps clarify things.

Pros of prepaying your mortgage

  • Financial freedom
  • Peace of mind
  • Reduction of overall interest expense
  • Receive better financial terms in the future

Robert Johnson, professor of finance in the Heider College of Business at Creighton University in Omaha, Nebraska, says prepaying your home loan may provide more financial freedom and peace of mind from debt.

“Once your mortgage is paid off, you have more flexibility to weather life’s setbacks like losing your job or needing extra funds for a health emergency,” he says.

Paying off your mortgage loan early can also give you the latitude to fund other needs and wants in life, like your child’s college savings, a new car, or future medical bills.

“One cannot understate the psychological benefits many people get from paying off a large debt. This is particularly true for individuals who have experienced financial hardships due to profound economic events like the Great Recession,” notes Johnson.

Real estate attorney Rajeh Saadeh agrees.

“If your interest rate is high, it’s a good idea to pay down the loan balance so that you’re not throwing as much money away in interest as you otherwise would be if you didn’t pay down the loan,” says Saadeh.

Plus, paying down your loan reduces your overall debt, which can make you more attractive to lenders if you need to take out another loan in the future, Saadeh adds.

Favorable math

Johnson provides a hypothetical example that illustrates how prepayment can yield large savings:

Say you just took out a 30-year, fixed-interest mortgage loan for $200,000 at 4%.

Your monthly payment on the principal and interest would be $955.

But if you upped the monthly payment to $1,479, you’d cut the loan’s term in half (to 15 years).

“In this example, over 30 years with no prepayments, you’d pay $343,800 in payments over the life of the loan – $200,000 of that would go toward your principal, and the remaining $143,800 represents interest paid on the loan.

“But if you prepay and cut the term down to 15 years, your total payments would be $266,200 ($66,220 of which would go toward interest) equating to a savings of $77,600,” Johnson explains.

Shea Adair, a full-time real estate investor and broker, puts it another way:

“Assume you have a 30-year fixed-rate mortgage of $150,000 at a 4.5% interest rate.

“You’ll pay $123,609 in interest over the life of that loan, assuming you make the minimum payment of $760,” says Adair.

“But if you increase the payment by $188 a month, to $948 total, you’ll pay off the mortgage in 20 years and save roughly $46,000 in interest.”

Cons of prepaying your mortgage

  • Diverts cash flow from other opportunities
  • Eventual loss of tax deduction

However, Alan Rosenbaum, CEO/founder of GuardHill Financial Corp, cautions that accelerating mortgage payments may not be a wise move.

“I would not recommend prepaying your mortgage while rates remain at historic lows. Prepaying your mortgage reduces the life of your loan, but that gives you less cash in your pocket that you could use to pay for other significant expenses or invest in the stock market,” he notes.

Also, once you no longer owe any interest, you’ll lose your tax deduction on mortgage interest you can claim, Rosenbaum says.

Brian Koss, executive vice president of Mortgage Network, seconds those thoughts.

“I don’t believe it’s wise to prepay unless you’ve paid off all other consumer debt, fully funded things like college and retirement savings, and built up six months of liquid reserves for times like we are going through now,” says Koss.

Calculating Investment Value

Johnson adds that many borrowers mistakenly view the purchase of their home as their chief investment when they should actually be valuing other investments higher. It’s as if they think buying a home is the same as a retirement plan.

“You should not simply compare the interest rate being paid on debt with the rate of return you believe you can earn on other investments,” notes Johnson. “Because mortgage interest is tax-deductible, the after-tax cost of debt can be computed by multiplying the interest rate times 1 minus the tax rate.”

Case in point:

If your mortgage rate is 5%, and you’re in the 30% marginal tax bracket, your after-tax mortgage debt is 5% x (1-0.30) = 3.5%.

Using this example, “if you can earn more than 3.5% on invested capital, you’d be better off investing the funds and not paying your mortgage down early,” Johnson recommends.

Comparing Alternatives to Prepaying Your Mortgage

Investing in the stock market: Alternative #1

Indeed, putting that extra money into stocks or retirement accounts instead could reap larger dividends.

“Nobel laureate economist Robert Shiller has made a compelling case that real estate, particularly residential homes, is a much inferior investment when compared to stocks. Shiller found that, on an inflation-adjusted basis, the average home price has increased only 0.6% annually over the past 100 years,” Johnson points out.

Contrast that with the stock market. Per data compiled by Ibbotson Associates, the average return on a large stock index (the S&P 500) has been approximately 10%, while inflation has been around 3%. That means the inflation-adjusted return of the stock market over the past 90 years has been approximately 7%.

“In addition, stocks don’t need a new furnace, the lawn mowed, or a new roof, and they don’t require annual property tax payments,” says Johnson. “The surest way to build wealth over long time horizons is to invest in a diversified portfolio of common stocks.”

Adair adds that, “A good rate of return on your money, in my opinion, is 7%. So if you took that extra $188 I talked about earlier and invested it in the stock market, over a 20-year period, it would likely equate to $51,000. That’s a bigger sum than the $46,000 you would have saved if you prepaid your mortgage over 20 years, although that doesn’t account for what you’d save in tax deductions as well.”

Problem is, no investment offers a guaranteed return. Stock values can fluctuate wildly – and, depending on the stocks you choose, you may lose money. By contrast, if you prepay your mortgage you are guaranteed a rate of return equal to your interest rate.

Refinancing your mortgage: Alternative #2

There’s possibly an even better choice: refinancing your mortgage.

“For those with good credit and who pay a higher rate currently, it’s an excellent time to refinance and take advantage of record low interest rates now,” suggests Saadeh.

Say you had a fixed-rate mortgage for $200,000 at 4.5% that has 30 years left. If you refinanced to a 3.375% interest rate for the same term and amount, you’d save $15,521 in interest over 30 years — without having to pay an extra dime (although you would incur closing costs when refinancing).

Best Candidate for Prepaying a Mortgage Loan

Saadeh says a good candidate for paying down their loan aggressively is anyone with an interest rate higher than the current prime rate:

“For example, say your mortgage rate is 5%. You may want to pay down your loan, as the prime rate is currently 3.25%. But if your mortgage rate is 3%, it wouldn’t make as much sense to pay it down.”

Johnson adds that individuals who lack the discipline to save money consistently may also benefit from prepaying their mortgage.

How To Make Accelerated Payments

Eager to start prepaying your mortgage?

Check first with your lender to confirm that your loan allows this (most do) and what steps are involved.

Typically, you need to write and mail a separate check to your lender. Specify in the memo field of the check that you want this money to go toward paying down your principal, or attach a separate note indicating this.

Also, contact your lender or log in to your mortgage account online a few days later to ensure that your extra payment has been received and properly applied toward the principal.

“Ask your lender about your options for making accelerated mortgage payments. They may suggest, for example, making a higher payment than what is due, making more frequent mortgage payments, paying by paper check, or paying over the phone,” Saadeh notes.

Be aware that, once you begin prepaying your mortgage, you can do so at your own pace by, for example, paying extra once a month, quarter, year, or at other frequencies you prefer.

Frequently Asked Questions

Q: My mobile home interest is 8% and feel I have been ripped off. I have been living here for 17 years and my home is not worth my balance. I think I was railroaded. Should I do a short sale or can they lower my interest rate?

A: The lack of equity in your mobile home after all this time makes it sound like there is a somewhat complicated history involved that may limit your options. Even so, it is worth exploring the possibilities to see which alternatives may be open to you.

Reviewing past and current mortgage rate history

For starters, while 8% sounds high by today’s standards, if your loan dates back to when you originally bought the mobile home 17 years ago, 8 percent does not seem so out of line. After all, current mortgage rates are about half what they were 17 years ago, and auto loan rates have experienced a similar drop over that time. Solid data on mobile home rates is not as easy to find. But since those loans can be thought of as combining some elements of both home mortgages and vehicle loans, it is reasonable to expect that they have dropped considerably in the past 17 years.

Of course, that assumes that you have had the same loan all that time, but the fact that your home is not worth your balance after all this time suggests that you have refinanced at least once. A combination of overly-aggressive refinancing and rapid depreciation of your property could well have left your loan under water. Unfortunately, that limits your options.

Options to deal with an underwater mortgage loan

Here are five possibilities at this point, depending on some of the details of your situation:

1. Refinance your mortgage

Unfortunately, your loan being under water probably eliminates most refinancing possibilities. However, it is possible that your current lender might be amenable to a rate reduction since they already own the risk of the underwater loan.

2. Use savings to retire part of the remaining loan

If you have savings accounts or other assets, you might pay the loan down to below the value of your property. This could open up more refinancing opportunities.

3. Put down savings to pay off all of the remaining loan balance

Given how low interest on savings accounts is these days, it might be worth using savings to retire the entire loan balance. Eliminating an 8 percent expense is better than earning 1 percent in deposit interest.

4. Initiate a short sale

You mention a short sale, but this would still require resources to retire the excess balance on the loan.

5. Stay in the home

If you can still afford your payments, your best option for the time being may be to stay put. After all, if you sell out, you are still going to have to pay for some other form of housing.

Your current loan rate and your lack of equity are certainly less the ideal. However, the important thing is to assess which of the above is your best option for the future, rather than trying to remake the past.

Q: My husband and I restructured our mortgage a few years ago when we were having trouble making the payments. The mortgage company agreed to reduce the payments for the first 10 years, but after that they are higher than ever. I’m starting to worry about it because things haven’t gotten any better for us financially. Our house still isn’t worth as much as we owe, so I’m wondering if we should just default on the loan now, rather than put another six years of payments into a property we’re likely to lose anyway. 

A: It’s a tough situation, but six years is a long time, and you may not want to give up just yet. Here are some variables you need to consider:

  1. How does your loan rate compare with current mortgage rates? Based on what you describe, you would have restructured your mortgage about four years ago, when mortgage rates were over half a point higher than today’s mortgage rates. There may be even greater potential to reduce your mortgage rate if you have since cleared up any black marks on your credit history, so this is one possibility to look into.
  2. How do your mortgage payments compare with rental costs? Never view any financial decision in isolation, but rather in comparison with alternatives. In this case, you have to compare your current mortgage costs with what it would cost you to rent. Unless you would save a lot by renting, it argues for staying in the home at least until the step-up in payments comes closer.
  3. How far is your home’s value from being above water? The home may not be worth what you owe now, but if it is getting closer there may be a realistic chance of it getting there within the next six years. That would give you a chance to sell before the higher payments hit, and walk away with some equity.
  4. How are your employment prospects? The job market is getting better, so depending on your health and your skills, there is a chance you could raise your income enough in six years to afford the higher payments.
  5. Is there room for any belt-tightening? You have probably already thought about this, but a ruthless round of budget cuts designed to make your mortgage a priority might allow you to build up enough of a reserve to cushion the impact of the increased payments.

You are right to be thinking ahead to when your payments expand, because you need a plan for dealing with that. However, there is still enough time for improving circumstances to put a viable plan more within your reach.

Q: My husband is 34. He is debating whether to use an old 401(k) from a previous employer to pay off the house. He has a new 401(k) that has about $15,000 in it and plans to leave it alone and continue to contribute to it. The 401(k) in question has about $130,000 in it. We owe $81,000 on the house and have 24 years left on the mortgage. So, after early withdrawal penalties and taxes, we’ll have enough to pay off the house, which will save us like $62,000 in interest over the life of the loan and free up about $600 a month. But is the cost of cashing that out worth it? 

A: Saving $62,000 in interest over the life of your mortgage sounds tempting. However, the other side of the equation is what you would have to give up to obtain those savings. When it comes to early withdrawals from a 401(k) plan, the price is generally not worth it. This may be especially true in your case because there may be alternatives to withdrawing from this fund that could save you a substantial amount of interest expense on your mortgage without causing you to take a hit to your 401(k) retirement savings.


Tax penalties vs. mortgage interest savings

Since your husband is younger than 59½, taking money out of his 401(k) to pay off your mortgage will mean first having to pay a 10% tax penalty for the early withdrawal, plus whatever tax rate you normally pay on income since the income tax was deferred when the money went into the plan.

Future investment earnings in danger

As a result, you are going to have to take out considerably more than $81,000 in order to have $81,000 left over after taxes to pay off your mortgage. Now think about the future investment earnings you will miss on the amount you take out. Even at a very modest rate of return, these earnings could very easily exceed the interest you would save on your mortgage. To find out how much your retirement fund will be worth in the future, use a retirement savings calculator to better inform your financial decisions.

Alternative to early withdrawals: Refinancing mortgage

Since you are six years into your mortgage, there is a good chance that the original loan was at a substantially higher interest rate than current mortgage rates. In this case, refinancing could save you a fair amount of interest, without you having to pay the tax penalty or give up future earnings on your current 401(k) balance.

Better yet, with six years of your loan paid off and refinance rates much lower these days, you could consider refinancing to a 15-year loan. In the long run, this would save you money in two ways. Rates on shorter mortgages are much lower than on 30-year home loans, plus you would save by paying interest over fewer years. In the near term, you would probably have to cope with a higher monthly payment, but you might find that the lower interest rate means this is affordable and well worth the long-term savings.
