Mortgages 101: Understanding the Differences Between ‘Open’ and ‘Closed’ Mortgages

Marci • July 28, 2014

If you’re planning to buy a home this year, you’re probably already investigating mortgages and the different options available to you. The reality is that for many families, home ownership is simply out of reach without taking on a mortgage. Mortgages come in a variety of forms, and it’s important to understand how they differ. ‘Open’ and ‘closed’ mortgages are two options you’ll often encounter when seeking funds to buy your home. Here’s what you need to know about these two different mortgage types, and what they mean for your financial future.

Open Versus Closed: Pay Periods and Penalties

The main difference between open and closed mortgages is that open mortgages allow early repayment, while closed mortgages do not. Every mortgage has a set repayment period that dictates what your payment schedule will be and when you will have paid your debt in full. A closed mortgage has a set repayment term, and full repayment of your mortgage prior to the end of this term will result in a penalty fee. In contrast, open mortgages offer repayment terms ranging from six months to several years, meaning you can repay your mortgage at your discretion without incurring penalties.
There is, though, one exception to the payment penalties for closed mortgages. Although you may not repay a closed mortgage in full prior to the end of the term, most of he time, you may remit up to 20 percent of the original mortgage amount per year by using a prepayment option. Talk to your mortgage advisor for a full explanation of how prepayment can expedite the mortgage repayment process.

Closed Mortgage Prepayment Penalties

If you decide to refinance or sell the property prior to the closed mortgage maturity date, you will incur a prepayment penalty equal to either three months’ interest or the Interest Rate Differential.
In the former case, three months’ interest is payable in one lump sum, while IRD applies only if current interest rates are below prevailing rates on the date of initial loan disbursement.
IRD is calculated by multiplying the difference between both percentage interest rates by outstanding balance and then by your remaining loan term. Thus, the earlier you repay the greater penalty you will incur in both the above scenarios.

That Pesky Interest: How Your Mortgage Type Changes Your Interest Rate

A typical mortgage will have an interest rate that is either fixed or variable. If your mortgage has a fixed interest rate, you pay a set percent of interest every month for the duration of your mortgage – and this amount never changes. If your mortgage has a variable interest rate, then the amount of interest you pay will fluctuate according to changes in the prime rate.
Regardless of whether your interest rate is fixed or variable, you will pay a different amount of interest for a closed mortgage than for an open mortgage. Open mortgages tend to have higher interest rates than closed mortgages, because in an open mortgage there is a lower probability that you will have the mortgage for the full term.

Open or Closed: Which is the Better Option?

Ultimately, deciding whether to opt for an open or closed mortgage will depend on your own personal needs and your plans for your financial future. If you have a limited income and require a set repayment schedule, a closed mortgage will give you the low interest rate and small monthly payment that you need. If, however, you have a higher amount of cash on hand and you expect to repay your mortgage very soon, an open mortgage will allow you to save a great deal of money in interest that you would have paid over the long term. Just be aware, however, that your interest rate may fluctuate over time – possibly making your monthly payments significantly higher than expected. The main consideration to make in deciding whether an open or closed mortgage is right for you is how long you plan to be paying off your mortgage. If you expect to pay off your mortgage extremely soon, an open mortgage is ideal. Otherwise, a closed mortgage is the safer option. Buying a home is a major purchase, and the mortgage you choose is one that will likely stay with you for most of your life. Open and closed mortgages offer vastly different terms that will appeal to different buyers, and it can be difficult to determine which option is your best bet.

Saving for a down payment is one of the biggest challenges first-time buyers face. What many don’t realize is that the Canadian government offers a program designed to make it easier—the Home Buyers’ Plan (HBP) . This program allows you to withdraw money from your RRSP to help purchase your first home, without immediate tax consequences. Here’s how it works: Who Qualifies? To be eligible, you generally need to be a first-time home buyer. In practical terms, this means you must not have owned a home in the past four years, nor lived in a property owned by your spouse or partner during that time. There are also special allowances if you’re living with a disability or helping a relative with a disability. In these cases, you can use the HBP even if you’ve owned a home more recently. How Much Can You Withdraw? Under the program, you can access up to $35,000 from your RRSP as an individual. Couples can combine their withdrawals for a total of $70,000 . These funds must have been in your RRSP for at least 90 days before you take them out. Paying It Back The HBP isn’t “free money”—it’s an interest-free loan from your own retirement savings. You’ll have 15 years to repay the full amount back into your RRSP, starting in the second year after withdrawal. Each year, the CRA will send you an HBP Statement of Account outlining how much needs to be repaid. If you don’t make your repayment in a given year, that amount will be added to your taxable income. Why It’s a Smart Strategy The HBP can give first-time buyers a powerful boost toward homeownership. It helps you put together a larger down payment, which can reduce your mortgage amount and monthly payments. Just remember: it’s important to balance the short-term benefit of homeownership with the long-term impact on your retirement savings. Next Steps Thinking about using the Home Buyers’ Plan? Let’s sit down and review whether it’s the right move for you. Together, we can create a strategy that gets you into your first home while keeping your future financial goals on track. 📞 Reach out anytime—it would be a pleasure to guide you through the process.

When it comes to selling your home, most people think the first call should be to a real estate agent. But the smartest first step often isn’t with your agent—it’s with an independent mortgage professional. Why? Because your mortgage plays a bigger role in your bottom line than most people realize. Planning to Buy After You Sell If selling means you’ll also be purchasing another property, you’ll want to know exactly where you stand financially before listing. Mortgage rules change regularly, and qualifying once doesn’t guarantee you’ll qualify again. Getting a pre-approval in place ensures you know what you can afford and eliminates surprises later. On top of that, reviewing the terms of your existing mortgage could uncover options you may not have considered. For example, porting your mortgage instead of arranging a brand-new one could save you thousands. Selling Without Buying Even if you aren’t planning to buy right away, there’s still an important step: understanding the cost of breaking your mortgage. Unless your mortgage is open, penalties apply—and they can be significant. By reviewing the numbers with a mortgage professional, you might find that simply adjusting your timeline could reduce or even avoid costly fees. Navigating Life Changes In situations like a marital breakdown, it can feel like selling the family home is the only path forward. But that’s not always the case. With the right guidance and a legal separation agreement, one spouse may be able to buy out the other, keeping the home and providing stability for everyone involved. The Bottom Line Selling your property is more than just putting a sign on the lawn—it’s about creating a financial plan that protects your equity and positions you for the best possible outcome. Before you take the leap, let’s sit down and review your options. 📞 If you’re ready to talk strategy and make sure you get top dollar for your property, I’d be happy to connect anytime.
