Refinancing to Consolidate Debt in BC: The Math and the Risk
Key Takeaways: Rolling high-interest consumer debt into a mortgage cuts interest cost by 70–80% — but extending amortization can wipe out those savings over the full loan life. You’re converting unsecured debt to secured (your home is now collateral for the credit card balance). The scenario that works: consolidate, keep same amortization, pay aggressively. The scenario that doesn’t: consolidate, reset to 25 years, run up the cards again.
The Monthly Savings Are Real
$45,000 at 19.99% = $9,000/year in interest. Same amount at 4.5% = $2,025/year. Difference: $6,975/year, $581/month. These numbers are not misleading. The question is what happens to total interest paid over the full amortization.
The Amortization Problem
Keep your 20-year remaining amortization: $45,000 at 4.5% over 20 years = ~$24,000 total interest. Reset to 25 years: ~$30,000 total interest. Aggressive credit card payoff ($1,200/month at 19.99%): paid off in ~4.5 years, ~$16,000 total interest. The credit card is more expensive per month — but may be cheaper total if you actually pay it down. Most people don’t.
The Two Scenarios
Scenario A (works): Consolidate + keep amortization + redirect savings to prepayments → total interest stays low, mortgage gone on schedule.
Scenario B (destroys wealth): Consolidate + reset to 25 years + run up cards again → six months later cards carry $20K again, alongside a larger mortgage.
Unsecured to Secured: What Changes
Before: credit card company can sue and damage credit. After: that debt is secured against your home. Default has direct property consequences. Consolidation only makes sense with a genuine plan to change the spending behaviour that created the debt.
Stress Test and Qualification
Debt consolidation refinancing triggers the full stress test (contract rate + 2%, min 5.25%). At June 2026 uninsured rates (~4.09–4.29%), operative qualifying rate is ~6.09–6.29%. High consumer debt raises your TDS ratio — consolidating reduces it, but you must still qualify on the new, larger mortgage balance.
The HELOC Alternative
HELOC rates (June 2026): prime + 0.50–1.0% = ~5.45–5.95%. Lower than credit cards (19.99%), higher than a refinanced mortgage (4.09–4.29%). Makes sense when you want to avoid a refinance penalty or preserve a locked-in low rate. See: HELOC vs. refinance BC.
Who This Works For
Works well with: $30K+ high-interest debt, sufficient equity (max 80% LTV refinance), a plan for freed-up cash flow, and changed spending patterns that created the debt.
The Numbers to Run
1) Current monthly interest cost. 2) Penalty to break current mortgage. 3) New monthly payment after consolidation. 4) Break-even months (penalty ÷ savings). 5) Total interest on consolidated amount over 5 years vs. direct paydown.

FAQ
Good idea to consolidate credit card debt into a mortgage in BC?
Depends on how you manage it. Rate reduction from 19.99% to ~4.09–4.29% is real. But amortization extension or returning to high-interest spending can erase the savings.
How much equity do I need?
Enough to refinance within 80% LTV after adding consolidated debt. Example: $900K home, $550K mortgage → $720K max refinance = $170K capacity.
Does this require a new appraisal?
Yes. Kelowna appraisals: $400–$600, 5–10 business days.
What is the risk?
Primary: unsecured debt becomes secured (home at risk). Secondary: amortization extension may cost more total interest. Third: behavioural — only works if cards stay near zero.
