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
You would have to find someone in the other state who wanted to swap.  This is conceivable but difficult if you want the houses to be the same value.  How do you find the one person who lives in the right place now and wants to move to the right area?   The normal way this situation is handled is to simply put your house on the market.  At the same time, you find a new house in the new location.  You arrange for a new mortgage for the new house and make purchase contingent on selling the old house.  Your buyer pays off your mortgage and gives you a bit left over that you use as a downpayment on the new house.   Note that you take a loss on closing costs when you do this.  This is why if you are in the position where you move frequently, you may be better off renting.   Sometimes an employer will help with this, paying for a long term hotel or short term rental.  This can give you more room to sell and buy the houses.   If you have to move right now, immediately, not in a few months when your housing situation is fixed, consider double renting.  You rent out your mortgaged house to someone and pay rent on a new place.  You may put some of your stuff in storage until you get into your permanent place.   The downside is that it can be harder to sell a house with a tenant until you are close to the end of the lease.  And of course, you are probably not in the best position to get or pay good rent.  Your situation restricts your options.  You might get stuck in this situation for a year so as to get the time that you need to line up a buyer.   Of course, you may get lucky and find someone who wants your old house as an investment property.  Such a person won't be bothered by a tenant.  But they usually want a good price.  After all, they want to make money off it.   There are those operations that advertise that they buy ugly houses.  They want a good deal.  You'll probably take a bath.  But they can buy quickly, so you can move on quickly.  No waiting until they find a buyer.   And I'm not saying that you can't do a swap like you want.  I'm just saying that you may find it difficult to find a swapping partner.  Perhaps an investment person would be up for it.  They take your house in trade for their house, letting you stay in their house until they can fix up your old house and either rent it or sell it.  The problem is that it may be hard to find such an investor who can handle a house where you are and has a house where you need to be.   I don't have a good suggestion for finding a swapping partner other than calling a lot of realtors and asking for suggestions.  Maybe a bit of online checking for properties where the owner's business is managing the sale. This might vary from other answers but I generally prefer to use debt before touching an emergency fund.  But one of the reasons I have an emergency fund is to that I can make sure I can cover any debt payments.  Essentially, this give you leverage.  You might start off with a small emergency such as needing a new refrigerator.  If you pull the cash out of the fund to pay this off immediately, you've depleted your account and if something major comes along, you might be short.  By using debt, you can often cover the costs with cash-flow and leave your risk buffer in place. Often, retailers will offer really sweet financing deals.  0% for 12 months or whatever.  Often, though, if you don't pay it off in time, they can be costly.  I'm not sure if this is legal (in the US) anymore but if it wasn't fully paid off in time, you'd be retroactively charged interest on the whole amount.  But if you have an emergency fund, you pretty much guarantee that won't happen.  The only time it will is if something else happens that requires the emergency fund to be cashed in.  But if things are that dire, the debt is unsecured.  You're credit may suffer but they can't come after your assets. It's not an either-or situation.  You give yourself options by having the cash available.  It allows you to take advantage of opportunities that might be too risky otherwise.  Ultimately what you want to be able to weather the storm in a situation where you have, say, a mortgage on a house that is underwater, the stock market is down, and you have no income.  In that situation, you don't want to liquidate your stock when it's down and you (probably) don't want to lose your home equity in a foreclosure. "For the mortgage, you're confusing cause and effect. Loans like mortgages generally have a very simple principle behind them: at any given time, the interest charged at that time is the product of the amount still owing and the interest rate. So for example on a mortgage of $100,000, at an interest rate of 5%, the interest charged for the first year would be $5,000. If you pay the interest plus another $20,000 after the first year, then in the second year the interest charge would be $4,000. This view is a bit of an over-simplification, but it gets the basic point across. [In practice you would actually make payments through the year so the actual balance that interest is charged on would vary. Different mortgages would also treat compounding slightly differently, e.g. the interest might be added to the mortgage balance daily or monthly.] So, it's natural that the interest charged on a mortgage reduces year-by-year as you pay off some of the mortgage. Mortgages are typically setup to have constant payments over the life of the mortgage (an ""amortisation schedule""), calculated so that by the end of the planned mortgage term, you'll have paid off all of the principal. It's a straightforward effect of the way that interest works in general that these schedules incorporate higher interest payments early on in the mortgage, because that's the time when you owe more money. If you go for a 15-year mortgage, each payment will involve you paying off significantly more principal each time than with a 30-year mortgage for the same balance - because with a 15-year mortgage, you need to hit 0 after 15 years, not 30. So since you pay off the principal faster, you naturally pay less interest even when you just compare the first 15 years. In your case what you're talking about is paying off the mortgage using the 30-year payments for the first 15 years, and then suddenly paying off the remaining principal with a lump sum. But when you do that, overall you're still paying off principal later than if it had been a 15-year mortgage to begin with, so you should be charged more interest, because what you've done is not the same as having a 15-year mortgage. You still will save the rest of the interest on the remaining 15 years of the term, unless there are pre-payment penalties. For the car loan I'm not sure what is happening. Perhaps it's the same situation and you just misunderstood how it was explained. Or maybe it's setup with significant pre-payment penalties so you genuinely don't save anything by paying early." The advantage of interest only mortgages is that they can increase your cashflow as you are only paying the interest and not any part of the principle. We have most of our investment loans on interest only for 10 years. When we got the loans about 6 to 7 years ago our LVR was only 60% and the property prices have increased by about 40% in that time. We also place our excess cashflow into offset accounts linked to the investment loans, so there is extra cash available in case things go bad. The disadvantage of interest only mortgages is that you are not paying off any principal for the length of the interest only period. If you are over extended this could cause problems as you need to rely totally on the price of the property going up for your equity to increase. As you are currently paying mortgage insurance leads me to believe your LVR is above 80%, so you would not have much equity available in your home. With an interest only loan this could pose you some problems. You should never try to over extend yourself, the slightest thing that goes wrong could get you into financial troubles. Always try to have some buffer to help you stay on your feet if circumstances do change for the worst. what you aim to do is a great idea and it will work in your favor for a number of reasons. First, paying down your loan early will save you lots in interest, no brainer. Second, keeping the account open will improve your credit score by 1) increases the number of installment trade lines you have open, 2)adds to your positive payment history and 3) varies your credit mix. If your paid your car off you will see a DROP in your credit score because now you have one less trade line. To address other issues as far as credit scoring, it does not matter(much) for your score if you have a $1000 car loan or a $100,000 car loan. what matters is whether or not you pay on time, and what your balance is compared to the original loan amount. So the quicker you pay DOWN the loans or mortgages the better. Pay them down, not off! As far how the extra payments will report, one of two things will happen. Either they will report every month paid as agreed (most likely), or they wont report anything for a few years until your next payment is due(unlikely, this wont hurt you but wont help you either). Someone posted they would lower the amount you paid every month on your report and thus lower your score. This is not true. even if they reported you paid $1/ month the scoring calculations do not care. All they care is whether or not you're on time, and in your case you would be months AHEAD of time(even though your report cant reflect this fact either) HOWEVER, if you are applying for a mortgage the lower monthly payment WOULD affect you in the sense that now you qualify for a BIGGER loan because now your debt to income ratio has improved. People will argue to just pay it off and be debt free, however being debt free does NOT help your credit. And being that you own a home and a car you see the benefits of good credit. You can have a million dollars in the bank but you will be denied a loan if you have NO or bad credit.  Nothing wrong with living on cash, I've done it for years, but good luck trying to rent a car, or getting the best insurance rates, and ANYTHING in life with poor credit. Yeah it sucks but you have to play the game. I would not pay down do $1 though because like someone else said they may just close the account. Pay it down to 10 or 20 percent and you will see the most impact on your credit and invest the rest of your cash elsewhere. While, from a money-saving standpoint, the obviously-right course of action is to make only the minimum payment on the 0% loan, there are potentially legal reasons to try to pay off a car loan early. With a mortgage, you are the legal owner of the property and any action by the lender beyond imposing fees (e.g. foreclosure) requires going through the proper legal channels. On the other hand, in most jurisdictions, you are not the legal owner of a car purchased on a loan, and a missed or even lost payment can result in repossession without the lender even having to go to court. So from a risk-aversion standpoint, there's something to be said for getting rid of car loans as soon as you can. "I'm going to give a simpler answer than some of the others, although somewhat more limited: the complicated loan parameters you describe benefit the lender.  I'll focus on this part of your question: You should be able to pay back whenever; what's the point of an arbitrary timeline? Here ""you"" refers to the borrower.  Sure, yes, it would be great for the borrower to be able to do whatever they want whenever they want, increasing or decreasing the loan balance by paying or not paying arbitrary amounts at their whim.  But it doesn't benefit the lender to let the borrower do this.  Adding various kinds of restrictions and extra conditions to the loan reduces the lender's uncertainty about when they'll be receiving money, and also gives them a greater range of legal recourse to get it sooner (since they can pursue the borrower right away if they violate any of the conditions, rather than having the wait until they die without having paid their debt). Then you say: And if you want, you can set a legal deadline. But the mere deadline in the contract doesn't affect how much interest is paid—the interest is only affected by how much money is borrowed and how long has passed. I think in many cases that is in fact how it works, or at least it is more how it works than you seem to think.  For instance, you can take out a 30-year loan but pay it off in less than 30 years, and the amount you pay will be less if you pay it off sooner.  However, in some cases the lender will charge you a penalty for doing so.  The reason is the same as above: if you pay off the loan sooner, you are paying less interest, which is worse for the lender.  Again, it would be nice for the borrower if they could just pay it off sooner with no penalty, but the lender has no reason to let them do so. I think there are in fact other explanations for these more complicated loan terms that do benefit the borrower.  For instance, an amortization schedule with clearly defined monthly payments and proportions going to interest and principal also reduces the borrower's uncertainty, and makes them less likely to do risky things like skip lots of payments intending to make it up later.  It gives them a clear number to budget from.  But even aside from all that, I think the clearest answer to your question is what I said above: in general, it benefits the lender to attach conditions and parameters to loans in order to have many opportunities to penalize the borrower for making it hard for the lender to predict their cash flow." I use an offset mortgage. (No interest is paid, but the amount in the savings account is subtracted from the outstanding mortgage amount before interest is calculated, so the mortgage is paid off faster by the interest amount saved). The money is instantly accessible and there is no tax as the benefit is reduced/saved interest. However, the mortgage rate is slightly higher, so it works best if your emergency funds are a reasonably large proportion of the mortgage amount outstanding.
