What are the advantages of paying off a mortgage quickly?
The main reason for paying your mortgage off quickly is to reduce risk should a crisis happen.  If you don't have a house payment, you have much higher cash flow every month, and your day-to-day living expenses are much lower, so if an illness or job loss happens, you'll be in a much better position to handle it. You should have a good emergency fund in place before throwing extra money at the mortgage so that you can cover the bigger surprises that come along. There is the argument that paying off your mortgage ties up cash that could be used for other things, but you need to be honest with yourself: would you really invest that money at a high enough rate of return to make up your mortgage interest rate after taxes?  Or would you spend it on other things?  If you do invest it, how certain are you of that rate of return?  Paying off the mortgage saves you your mortgage interest rate guaranteed. Finally, there is the more intangible aspect of what it feels like to be completely debt free with no payments whatsoever.  That feeling can be a game-changer for people, and it can free you up to do things that you could never do when you're saddled with a mortgage payment every month. Considering that it's common for the monthly mortgage payment to be 25% of one's income, it's an obvious advantage for that monthly burden to be eliminated.  The issue, as I see it, is that this is the last thing one should do in the list of priorities: The idea of 'no mortgage' is great. But. You might pay early and have just a few years of payments left on the mortgage and if you are unemployed, those payments are still due. It's why I'd suggest loading up retirement accounts and other savings before paying the mortgage sooner. Your point, that rates are low, and your expected return is higher, is well presented. I feel no compulsion to prepay my 3.5% mortgage.  As the OP is in Canada, land of no mortgage interest deduction, I ignore that, till now. The deduction simply reduces the effective rate, based on the country tax code permitting it. It's not the 'reason' to have a loan. But it's ignorant to ignore the math. I used to think that paying off ahead of time made sense, but I no longer do, at least in most cases.  The upside is that you can get a return on your money equal to the mortgage interest rate (it's less than that in the US, where mortgage interest is deductible, so it's roughly the mortgage interest rate * 1 - your marginal income tax rate).  There are a few downsides. The biggest is that cash is the most liquid asset you can have; you can get at it with no restrictions. If you put that cash into your house, you are converting that into an asset with a lot of restrictions; you can't get at it without fees, nor can you get at it if you don't have a job, which is when you would need it most.  So, you are putting your money in a hard-to-get-at place for a small interest rate. I don't think it is worthwhile. (edit) One complication is PMI. If you are currently paying PMI, it may make sense to put money towards the mortgage until you get to 20% and can get rid of the PMI. It depends on where you are in life, and where you want to be at some point in the future, and the taxes, expenses and income at those points in your life. You don't get a mortgage to save on taxes, or keep a mortgage to save on taxes. But if somebody said they want to have the house paid off before they retire, that sounds to me like a great plan. They do need to balance it with saving for retirement, emergency fund, and college costs for themselves or their children.  Without having the whole picture it is impossible to say doing X is always a good idea. The financial reasons, beyond simply owning your home outright, are: You're no longer paying interest. Yes, the interest is tax-deductible in the U.S. (though not in Canada), but the tax savings is a percentage of a percentage; if you paid, say, $8000 in interest last year, at the 25% marginal rate you effectively save $2000 off your taxes. But, if you paid off your home and had that $8000 in your pocket, you'd pay the $2000 in taxes but you'd have $6000 left over. Which is the better deal? In Canada, the decision gets even easier; you pay taxes on the interest money either way, so you're either spending the $8000 in interest, lost forever as cost of capital, or on other things. Whatever you're earning is going into your own pocket, not the bank's. Similar to the interest, but also including principal, a home you own outright is a mortgage payment you don't have to make. You can now use that money, principal and interest, for other things. Whether these advantages outweigh those of anything else you could do with a few hundred grand depends primarily on the rate of return. If you got in at the bottom of the mortgage crisis (which is pretty much right now) and got a rate in the 3-4% range, with no MIP or other payment on top, then almost anything you can do with the amount you'd need to pay off a mortgage principal would get you a better rate of return. However, you'll need some market savvy to avoid risks.  In most cases when someone has pretty much any debt and a big wad of cash they're considering how to spend, I usually recommend paying off the debt, because that is, in effect, a risk-free way to increase the net rate of return on your total wealth and income. Balancing debt with investments always carries with it the risk that the investment will fail, leaving you stuck with the debt. Paying the debt on the other hand will guarantee that you don't have to pay interest on that outstanding amount anymore, so it's no longer offsetting whatever gains you are making in the market on your savings or future investments. From my experience and friends' experiences, I can say that there are advantages and disadvantages for paying off your mortgage quickly. Basically, it depends on these factors: the type of the mortgage, its interest rate, your financial stability, your skills in making investments and other outside factors, such as inflation, liquidity, oppurtunity cost, etc. Paying it off means you save on interest ratings, you decrease investment risks and your investment rates are taxable. Disadvantages are that you cannot use this money for investing, you cannot use this money for tax deductions and that in a state of inflation, not paying it off in advance could save you a lot of money.  However, I always recommend to read some more on websites that deal with mortgages, and speak with the mortgage expert in your bank.Just acquire enough information to make a good assessment. An interesting article on this topic - The Advantages and Disadvantages of Paying Off Your Mortgage
"that would deprive me of the rental income from the property. Yes, but you'd gain by not paying the interest on your other mortgage.  So your net loss (or gain) is the rental income minus the interest you're paying on your home.  From a cash flow perspective, you'd gain the difference between the rental income and your total payment. Any excess proceeds from selling the flat and paying off the mortgage could be saved and use later to buy another rental for ""retirement income"".  Or just invest in a retirement account and leave it alone.  Selling the flat also gets rid of any extra time spent managing the property. If you keep the flat, you'll need a mortgage of 105K to 150K plus closing costs depending on the cost of the house you buy, so your mortgage payment will increase by 25%-100%. My fist choice would be to sell the flat and buy your new house debt-free (or with a very small mortgage).  You're only making 6% on it, and your mortgage payment is going to be higher since you'll need to borrow about 160k if you want to keep the flat and buy a $450K house, so you're no longer cash-flow neutral. Then start saving like mad for a different rental property, or in non-real estate retirement investments." "The main disadvantage is that interest rates are higher for the interest-only loan. It's higher risk to the bank, since the principal outstanding is higher for longer.  According to the New York Times, ""Interest rates are usually an eighth- to a half-percentage point higher than on fully amortized jumbo loans."" They're also tougher to qualify for, and fewer lenders offer them, again due to the risk to the bank. Since you can always put extra towards the principal, strictly speaking, these are the only  downsides. The upside, of course, is that you can make a lower payment each month. The question is what are you doing with this? If this is the only way you can afford the payments, there's a good chance the house is too expensive for you. You're not building equity in the home, and you have the risk of being underwater if the house price goes down. If you're using the money for other things, or you have variable income, it might be a different story. For the former, reinvesting in a business you own might be a reason, if you're cognizant of the risks. For the latter, salespeople on commission, or financial industry types who get most of their income in bonuses, can benefit from the flexibility." Besides the reason in @rhaskett's answer, it is important to consider that paying off a 30-year mortgage as if it was a 15-year is much more inconvenient than just paying the regular payments of a 15-year mortgage.  When you pay extra on your mortgage, some lenders do not know what to do with the extra payment, and need to be told explicitly that the extra needs to be applied toward the principal.  You might need to do this every month with every payment.  In addition, some lenders won't allow you to set up an automatic payment for more than the mortgage payment, so you might need to explicitly submit your payment with instructions for the lender each month, and then follow up each month to make sure that your payment was credited properly.  Some lenders are better about this type of thing than others, and you won't really know how much of a hassle it will be with your lender until you start making payments. If you intend to pay it off in 15 years, then just get the 15-year mortgage. "I've heard that the bank may agree to a ""one time adjustment"" to lower the payments on Mortgage #2 because of paying a very large payment. Is this something that really happens? It's to the banks advantage to reduce the payments in that situation.  If they were willing to loan you money previously, they should still be willing.  If they keep the payments the same, then you'll pay off the loan faster.  Just playing with a spreadsheet, paying off a third of the mortgage amount would eliminate the back half of the payments or reduces payments by around two fifths (leaving off any escrow or insurance).   If you can afford the payments, I'd lean towards leaving them at the current level and paying off the loan early.  But you know your circumstances better than we do.   If you are underfunded elsewhere, shore things up.  Fully fund your 401k and IRA.  Fill out your emergency fund.  Buy that new appliance that you don't quite need yet but will soon.  If you are paying PMI, you should reduce the principal down to the point where you no longer have to do so.  That's usually more than 20% equity (or less than an 80% loan).   There is an argument for investing the remainder in securities (stocks and bonds).  If you itemize, you can deduct the interest on your mortgage.  And then you can deduct other things, like local and state taxes.  If you're getting a higher return from securities than you'd pay on the mortgage, it can be a good investment.  Five or ten years from now, when your interest drops closer to the itemization threshold, you can cash out and pay off more of the mortgage than you could now.   The problem is that this might not be the best time for that.  The Buffett Indicator is currently higher than it was before the 2007-9 market crash.  That suggests that stocks aren't the best place for a medium term investment right now.   I'd pay down the mortgage.  You know the return on that.  No matter what happens with the market, it will save you on interest.  I'd keep the payments where they are now unless they are straining your budget unduly.  Pay off your thirty year mortgage in fifteen years." "So, let's take a mortgage loan that allows prepayment without penalty. Say I have a 30 year mortgage and I have paid it for 15 years. By the 16th year almost all the interest on the 30 year loan has been paid to the bank This is incorrect thinking.  On a 30 year loan, at year 15 about 2/3's of the total interest to be paid has been paid, and the principal is about 1/3 lower than the original loan amount.  You may want to play with some amortization calculators that are freely available to see this in action.   If you were to pay off the balance, at that point, you would avoid paying the remaining 1/3 of interest.   Consider a 100K 30 year mortgage at 4.5% In month two the payment breaks down with $132 going to principal, and $374 going to interest.  If, in month one, you had an extra $132 and directed it to principal, you would save $374 in interest.  That is a great ROI and why it is wonderful to get out of debt as soon as possible.   The trouble with this is of course, is that most people can barely afford the mortgage payment when it is new so lets look at the same situation in year 15. Here, $271 would go to principal, and $235 to interest.  So you would have to come up with more money to save less interest.  It is still a great ROI, but less dramatic.   If you understand the ""magic"" of compounding interest, then you can understand loans.  It is just compounding interest in reverse.  It works against you." "I went through the process so I'll add my experience for posterity. On the morning of the day I was ready to pay, I went to my mortgage company's web site and got an instant payoff statement dated for the same day. This had the final payoff amount as well as addresses to send checks and information about wiring. I printed this statement out and took it to my bank the same day and told them that I wanted to wire money. They referred to the printout and sent the money to the mortgage company. The next day, the mortgage company web site indicated that the loan was paid in full. Although sending a check (and the payoff statement indicated that cashier's checks were ""preferred""), wiring the money was an easy process and helped me to overcome my concerns about  situations that  might arise if mail had been used (i.e. I did not want to deal with the complexity of day-late/day-early fees/credits, and I did not want to worry about the complexity of potentially losing a cashier's check in the mail)." Advantages of buying: With every mortgage payment you build equity, while with rent, once you sign the check the money is gone. Eventually you will own the house and can live there for free. You can redecorate or remodel to your own liking, rather than being stuck with what the landlord decides is attractive, cost-effective, etc. Here in the U.S. there are tax breaks for homeowners. I'm not sure if that's true in U.K. Advantages of renting: If you decide to move, you may be stuck paying out a lease, but the financial penalty is small. With a house, you may find it difficult to sell. You may be stuck accepting a big loss or having to pay a mortgage on the empty house while you are also paying for your new place. When there are maintenance issues, you call the landlord and it's up to him to fix it. You don't have to come up with the money to pay for repairs. You usually have less maintenance work to do: with a house you have to mow the lawn, clear snow from the driveway, etc. With a rental, usually the landlord does that for you. (Not always, depends on type of rental, but.) You can often buy a house for less than it would cost to rent an equivalent property, but this can be misleading. When you buy, you have to pay property taxes and pay for maintenance; when you rent, these things are included in the rent. How expensive a house you can afford to buy is not a question that can be answered objectively. Banks have formulas that limit how much they will loan you, but in my experience that's always been a rather high upper bound, much more than I would actually be comfortable borrowing. The biggest issue really is, How important is it to you to have a nice house? If your life-long dream is to have a big, luxurious, expensive house, then maybe it's worth it to you to pour every spare penny you have into the mortgage. Other people might prefer to spend less on their house so that they have spare cash for a nice car, concert tickets, video games, cocaine, whatever. Bear in mind that if you get a mortgage that you can just barely afford, what do you do if something goes wrong and you can't afford it any more? What if you lose your job and have to take a lower-paying job? What if some disaster strikes and you have some other huge expense? Etc. On the flip side, the burden of a mortgage usually goes down over time. Most people find that their incomes go up over time, between inflation and growing experience. But the amount of a mortgage is fixed, or if it varies it varies with interest rates, probably bouncing up and down rather than going steadily up like inflation. So it's likely -- not at all certain, but likely -- that if you can just barely afford the payment now, that in 5 or 10 years it won't be as big a burden. "Making extra principal payments will reduce the term of your loan. I wouldn't sign up for a biweekly schedule, just do it yourself so you have more flexibility. A simple spreadsheet will allow you to play ""What if?"" and make it clear that extra principal payments are most effective early in the term of the loan. My wife and I paid off our home in less than 10 years with this approach. Some will say that the opportunity costs of not using that money for something else outweighs the gains. I would say that not having a mortgage has a positive impact on your cash flow and your assets (you own the home), which combine to create more opportunity, not less. That being said, It should be obvious that paying off higher interest debt first is the priority, (Paying off a zero percent interest car loan early is just foolish)" Aggressively paying of Mortgage is better. If you have more cash available [assuming you have covered all other aspects i.e. emergency funds, retirement etc], the only question you need to ask is where will you invest and what returns would you get. So if your mortgage is say at 5%, if the spare money can get you more than this, its beneficial, if its in Bank CD with say near zero interest, its not worth it. However if you are sure you can make 10% returns on the investments, then go ahead and don't pay the mortgage aggressively. Use the $11k to pay down either car loan (your choice). You should be able to clear one loan very quickly after that lump sum. After that, continue to aggressively pay down the other car loan until it is clear. Lastly, pay off the mortgage while making sure you are financially stable in other areas (cash-on-hand, retirement, etc) Reasoning: The car loans are very close in value, making it a wash as far as payoff speed. The 2.54% interest is not a large factor here. As a percentage of all these numbers, the few bucks a month isn't going to change your financial situation. This is assuming you will pay off both loans well ahead of schedule, making the interest rate negligible in the answer. Paying off the mortgage last is due to the risk associated with the car loans. The cars are guaranteed to lose value at an alarming rate. While a house certainly may lose value, it is far from an expectation. It is likely that your house will maintain and/or increase in value, unless you have specific circumstances not disclosed here. This makes the mortgage a lower risk loan in your financial world. You can probably sell the house to clear the loan balance if necessary. The cars are far more likely to depreciate beyond the loan balance. Certainly, paying off the mortgage is better than doing nothing with the money. But it gets interesting when you consider keeping the mortgage and investing the money. If the mortgage rate is 5% and you expect >5% returns from stocks or some other investment, then it might make sense to seek those higher returns. If you expect the same 5% return from stocks, keeping the mortgage and investing the money can still be more tax-efficient. Assuming a marginal tax rate of 30%, the real cost of mortgage interest (in terms of post-tax money) is 3.5%*. If your investment results in long-term capital gains taxed at 15%, the real rate of growth of your post-tax money would be 4.25%. So in post-tax terms, your rate of gain is greater than your rate of loss. On the other hand, paying off the mortgage is safer than investing borrowed money, so doing so might be more appropriate for the risk-averse. * I'm oversimplifying a bit by assuming the deduction doesn't change your marginal tax rate. Sounds fishy - taking out more debt to pay the main mortgage down faster? There are a couple of issues I can see: I would think that a much more sensible strategy with a lot less risk is to save up extra cash and send your lender a check every quarter or six months. In the US, a surviving family member that inherits the entire property may also assume the mortgage.  If the new mortgagee fails to uphold the terms of the mortgage (i.e. make timely payments), the mortgagor can begin foreclosure proceedings.  There is generally no requirement to pay off the mortgage quickly. This is obviously the simple case where one person inherits the entire property. If the estate is split and no one person inherits the house, or if the house is left to a non-relative, things get more complicated.  Effectively in that case the house is either sold to pay off the mortgage or the inheritor needs to take out a new mortgage to pay off the old one. The answer depends entirely on your mortgage terms - is the interest rate low, how many years left? Questions like this are about Cost of Capital. If your mortgage has a low interest for a lot of years, you have a low cost of capital.  By paying it off early, you are dumping that low cost of capital. Use the extra money to start a business, invest in something or even buy another property (rental).  Whenever you have a low cost of capital, don't rush to get rid of it. Of course, if there are no other investment/business opportunities available and the extra money is going into a low return savings account, you might as well pay down your debt.  Or if you lack the self discipline to use the extra money properly - buying flat screens and meals out - then yeah just pay down your debt. But if you're disciplined with the extra money, use it to get access to more capital and make that new capital work for you. Answers to this your question break down along a few lines regarding opportunity costs of tying up a significant chunk of your salary and assets in one piece of property, as opposed to other things you'd like to do with your life.  The 30 year standard mortgage was invented in the 30's as part of FDR's new deal to make housing affordable to more people, while relieving the strain on the market of foreclosed homes from ~10 year interest only balloon mortgages (sound familiar?). The 30 year term tends to follow the career of the average American of that era, allowing them to pay the house off and live out the remainder of their lives there at a lower cost.  Houses are depreciating assets because they wear out over time. Their greatest investment value is a place to live. The appreciation on a home comes from the real estate it sits on and the community the property is located in. Value is determined by desirability of the house and community in their current state, and the supply of property in the area. This value can only be extracted when you sell the home. This partially answers your last question noting that you shouldn't buy a really expensive building for investment value. We've learned in recent years that there are no long term guarantees of property value either, because land and communities can decrease in value due to unemployment, over supply, crime, pollution, etc. Only buy as much home as you will need in the next decade or so, in a place that you will like living over that time period, and don't consider it much of an investment. I will tell you to get a fifteen year fixed rate mortgage since it's readily available at lower rates and has a significantly lower total purchase price than the standard 30 years. The monthly payment difference isn't that great, and anyone who looks at the monthly payment as opposed to the total costs, your priorities and the opportunity costs shouldn't be trusted for financial advice. I don't like debt. There are psychological benefits to being free from the bondage and drain of a long term mortgage on your finances.  The biggest argument for paying off your home quickly is freedom to pursue other desires with all of your salary and the assets you have available to you. Some financial advisers will tell you to keep your mortgage costs under 25% of your income, so that you can actually live off the money you make. I would also recommend paying at least enough into your 401k to get the company match and fully funding your Roth IRA. I'd also have an emergency fund to cover at least 6 months of expenses, including this mortgage in case you lose your job. A 15 or 20 year mortgage will give you breathing room to take care of these other priorities, and you can overpay on almost any mortgage to decrease the principal and finish in a shorter time period (make sure to get a mortgage that allows prepayment) . More financially savvy people may tell you to take the 30 year mortgage and invest the difference. Especially with mortgage rates around 4%, this is a very cheap way to increase your purchasing power and total assets. Most people lack the investment prowess and self discipline to make this plan pay off. There are even fewer guarantees regarding markets and investments than property. This also is a way of diversifying your total assets to protect against loss of value in your home. This approach has backfired for thousands of people who are underwater on their homes. This problem is often compounded by job loss forcing you to move, or increasing your commute, making your home less desirable for you. Some people will tell you to maintain the mortgage for the tax credit. This fails a basic math test since you only get about a quarter of the money (depending on your tax rate) that you are paying in interest back from the government. The rest of the money goes to bank at no gain to you. This approach is basically a taxpayer subsidized decrease of your 4% interest payment to a 3% interest payment (assuming you have ~ $5000 in other deductions), and only pays off if you can successfully invest the money at a rate somewhat greater than 3%.
