Rolling High-Interest Debt Into Your Mortgage

If you're carrying credit card balances, a line of credit, or a car loan at a steep interest rate, you may have wondered whether tapping into your home equity could simplify things. Rolling multiple debts into your mortgage can lower your monthly interest costs in some cases, but it also changes the shape of your debt in ways worth understanding before you sign anything.

How Debt Consolidation Through Refinancing Works

When you refinance to consolidate debt, you're essentially replacing your existing mortgage with a new, larger one and using the difference to pay off other debts. Most Canadian lenders allow you to borrow up to 80% of your home's appraised value through a refinance, which can open up a meaningful amount of equity depending on how long you've owned the property and how much it has appreciated.

For example, if a home is worth $650,000 and the remaining mortgage balance is $350,000, a homeowner could potentially access up to $170,000 in equity (bringing the total mortgage to 80% of value), assuming they qualify. That equity could then be used to pay off credit cards, a car loan, or other high-interest debt in one lump sum.

This type of refinance usually means breaking your current mortgage term, which can trigger a prepayment penalty if you're not yet at renewal. It also means requalifying for the new mortgage amount, including passing the federal mortgage stress test, even though you already own the home.

Why the Math Can Work in Your Favour

Credit card interest rates in Canada often sit in the 19% to 24% range, while unsecured personal loans and lines of credit tend to run lower but are still typically higher than mortgage rates. Mortgage rates, by comparison, are generally much lower because the loan is secured against your property, which represents less risk for the lender.

To illustrate, someone carrying $25,000 in credit card debt at 20% interest making minimum payments could be paying a substantial amount in interest alone each year, with very little going toward the principal. Rolling that same $25,000 into a mortgage at a considerably lower rate could reduce the interest cost significantly, though the actual savings depend on your specific rate, amortization, and how the lender structures the new mortgage.

The trade-off is time. Spreading that $25,000 over a 25-year amortization instead of paying it off over two or three years could mean paying more in total interest over the life of the loan, even at a lower rate, unless you make extra payments or adjust your amortization to pay it down faster.

Costs and Risks to Think Through

Refinancing isn't free. You may face a prepayment penalty for breaking your current term, legal fees, an appraisal fee, and potentially a mortgage discharge fee. If your new mortgage amount pushes you above 80% loan-to-value, you won't qualify for this type of refinance at all, since Canadian rules generally cap conventional refinances at that threshold and CMHC insurance isn't available for debt consolidation refinances.

There's also a more personal risk. Converting unsecured debt, like credit card balances, into secured debt against your home means that if you were ever unable to make payments, the consequences are more serious since your home is now tied to that debt. Unsecured creditors generally can't seize your home directly, but a mortgage default puts your property at risk.

It's also worth being honest about spending habits. If the credit card debt gets paid off but the underlying spending patterns don't change, it's possible to end up back in debt on those cards while now also carrying a larger mortgage.

Alternatives Worth Comparing

A full mortgage refinance isn't the only way to access home equity for debt consolidation. A home equity line of credit (HELOC) allows you to borrow against your equity without necessarily breaking your existing mortgage term, though HELOC rates are typically variable and tend to be somewhat higher than fixed mortgage rates. Some homeowners also consider a second mortgage, which can be useful if breaking the first mortgage isn't financially sensible, though second mortgages often carry higher interest rates and fees.

For those who are close to their mortgage renewal date, waiting until renewal to consolidate debt could help avoid a prepayment penalty entirely, since you'd be setting new terms anyway. A mortgage professional can run the numbers on penalty costs versus interest savings to help determine whether refinancing now or waiting makes more sense for your specific situation.

Key Takeaways

• Refinancing to consolidate debt means increasing your mortgage balance, typically up to 80% of your home's value, to pay off higher-interest debts.
• Lower mortgage rates compared to credit cards can reduce monthly interest costs, but spreading debt over a longer amortization may increase total interest paid.
• Breaking your current mortgage term to refinance often triggers a prepayment penalty, plus appraisal and legal fees.
• Converting unsecured debt into mortgage debt puts your home at greater risk if you're unable to keep up with payments.
• HELOCs, second mortgages, or waiting until renewal are alternatives worth comparing before committing to a full refinance.
