Should you refinance your mortgage to pay off debt?
Over the past few years, many Canadians have found themselves carrying more debt than they ever expected.
Higher interest rates, rising grocery bills, increased insurance premiums, and the overall cost of living have made it harder for many households to stay ahead. If you've built up equity in your home, it's only natural to wonder whether refinancing your mortgage could help.
For some homeowners, it can be one of the smartest financial decisions they ever make. For others, it can end up costing thousands of dollars more than necessary.
Like most financial decisions, the right answer depends on your situation.
Before using your home to pay off other debts, it's important to understand both the advantages and the trade-offs involved.
When Refinancing to Pay Off Debt Can Make Sense
Not all debt is created equal.
If you're carrying balances on high-interest credit cards or unsecured lines of credit, replacing those debts with a mortgage can significantly reduce the interest you're paying each month.
For example, it's not uncommon to see:
Credit cards charging 20% or more
Unsecured lines of credit around 8–12%
Mortgage rates that are often considerably lower
By consolidating those debts into your mortgage, many homeowners can simplify their finances by replacing several monthly payments with one. In many cases, it can also improve monthly cash flow, making it easier to get back on solid financial footing.
The Trade-Off
This is the part many people don't talk about. Just because refinancing can lower your monthly payments doesn't necessarily mean it's always the cheapest option.
Let's use a simple example.
Imagine you have $30,000 in credit card debt charging 20% interest. If you're able to aggressively pay that debt off over the next two years, you'd pay roughly $6,500 in interest.
That's a big "if," and it's where many people struggle.
Now compare that to rolling the same $30,000 into your mortgage at 5% over 20 years. Your monthly payment on that portion of the mortgage would drop dramatically (roughly $200 per month), which could provide some much-needed breathing room. However, over those 20 years, you'd end up paying roughly $17,500 in interest on that same $30,000.
So does that mean refinancing is a bad idea?
Not at all. The real question is this: Can you realistically eliminate the debt in a short period of time without putting yourself under financial strain?
If the answer is yes, you'll often pay far less interest by sticking to an aggressive repayment plan. But if you're already struggling to keep up with monthly payments, carrying balances from month to month, or watching your debt slowly grow despite your best efforts, refinancing may be exactly the tool that helps you break the cycle.
That's why I encourage clients to think of refinancing as a cash-flow solution, not simply an interest-rate solution. Done properly, the goal isn't to create more spending money. It's to create enough breathing room to regain control of your finances and move forward with a plan.
It's Not Just About the Interest Rate
Many people assume refinancing is simply a matter of comparing interest rates. In reality, there are several other factors to consider.
Questions I often discuss with clients include:
How much equity do you have available?
Will refinancing trigger a prepayment penalty on your existing mortgage? (Related: Should I break my mortgage early?)
Are there legal or appraisal costs involved?
Will extending your amortization help your cash flow?
Would another solution better accomplish your goal?
If all of that sounds a little overwhelming, don't worry. Many lenders offer incentives to help with things like appraisal costs, legal fees, or switching your mortgage. Every situation is different, but don't assume refinancing is off the table just because it looks complicated at first glance.
Are There Alternatives?
Refinancing isn't the only way to access your home's equity.
Depending on your situation, other options could include:
A HELOC (Home Equity Line of Credit) if you don't need all the funds immediately. Learn more about HELOCs.
A second mortgage if qualifying for a larger first mortgage is difficult. Learn more about second mortgages.
A reverse mortgage for eligible homeowners looking to access equity later in life. Learn more about reverse mortgages.
or simply creating a repayment plan if the debt can realistically be paid off within a relatively short period. The right solution depends on your financial goals, your income, and your long-term plans—not just your interest rate.
Before You Decide
Before refinancing to pay off debt, ask yourself:
Is this debt the result of a temporary situation or an ongoing spending pattern?
Will lowering my monthly payments actually improve my financial position?
Am I comfortable paying this debt over a longer period?
Is there another solution that better fits my goals?
There aren't always right or wrong answers, but there are usually better and worse options depending on your circumstances.
Final Thoughts
Using your home's equity to pay off debt can be a smart financial move.
It can lower monthly payments, reduce interest costs, and provide valuable breathing room during a difficult period.
At the same time, it's a decision that deserves careful thought. Your home is often your largest financial asset, so it's worth making sure the solution you're choosing not only solves today's problem but also supports your long-term financial goals.
Sometimes refinancing is exactly the right solution. Sometimes it isn't. The key is making sure the decision improves not only today's cash flow, but your long-term financial picture as well.
Common Questions
-
It can be. If you're paying high interest on unsecured debt, refinancing may reduce your monthly payments and total interest costs. However, it's important to consider how long you'll be repaying that debt and whether refinancing aligns with your long-term financial goals.
-
It often can, particularly if you're extending your amortization or consolidating higher-interest debt into your mortgage. Whether it makes sense depends on your overall financial situation.
-
Possibly. Most lenders allow homeowners to refinance up to 80% of their home's current value, assuming they meet the lender's qualification requirements.
