Should I Refinance My Mortgage? How to Decide

Refinancing means replacing your current mortgage with a new one — often to access equity, lower your rate, or consolidate debt. Done for the right reasons, it can save you real money or fund a smart move. Done for the wrong ones, it can cost you in penalties and added interest. This guide helps you decide whether refinancing is worth it for your situation, and how to run the numbers before you commit.

Key takeaways

• Refinancing replaces your existing mortgage with a new one, often to access equity, lower your rate, or consolidate debt.
• It usually requires re-qualifying under the stress test at the greater of your contract rate + 2% or 5.25%.
• Breaking your current mortgage early can trigger a penalty — factor it into the math.
• You can typically refinance up to 80% of your home's value; refinanced mortgages can't be insured.
• HOMEH offers a free refinance calculator and the industry's highest Cashback Rebate to eligible buyers. Sellers list for 1%, or free when they also buy with HOMEH within 6 months, or $395 + HST with a Mere Posting.

What refinancing actually means

Refinancing is taking out a new mortgage to replace your existing one — usually before your term is up. Because you're breaking the current contract, it's different from a renewal, where you simply continue at term-end. If your term is ending soon, compare the two paths in our mortgage renewal guide.

People refinance to access home equity in cash, lower their interest rate, change their amortization, or roll high-interest debts into one lower-rate payment. In Canada you can typically refinance up to 80% of your home's value, and refinanced mortgages cannot be insured.

It helps to think of refinancing as a deliberate financial reset rather than a routine step. Because you're opening a brand-new mortgage, you'll go through underwriting again, pay closing costs such as legal and appraisal fees, and possibly a penalty to exit your current deal. Those costs are exactly why refinancing should always be backed by clear numbers, not just the appeal of a lower advertised rate.

Good reasons to refinance

Refinancing can make strong financial sense when:

• Rates have dropped enough that your interest savings outweigh any penalty to break early.
• You're carrying high-interest debt (credit cards, loans) that could be consolidated at a much lower mortgage rate.
• You need funds for a major goal — renovations, education, or an investment — and your home equity is the cheapest source.
• You want to change your mortgage structure, such as a shorter amortization to pay off faster.

When refinancing may not be worth it

Refinancing isn't always the answer. The penalty to break your current mortgage can be large — especially on a fixed-rate mortgage, where the interest rate differential (IRD) applies. If you're close to renewal, it's often better to wait. And consolidating debt only helps if you avoid running the balances back up.

Mind the penalty

Breaking a closed mortgage early usually triggers a penalty — roughly three months' interest on a variable mortgage, or the larger IRD on a fixed one. Always weigh the penalty against your projected savings. See mortgage penalties explained.

The stress test still applies

Refinancing means re-qualifying. At a federally regulated lender you must again pass the stress test, proving you can afford payments at the greater of your contract rate plus 2% or 5.25%. Your debt-service ratios apply too:

If your income has dropped or your debts have grown, re-qualifying can be the hardest part. Ironically, the borrowers who most want to consolidate debt through refinancing are sometimes the ones who struggle to pass the stress test, because their existing debt load pushes their TDS above the guideline. Brush up in what is the mortgage stress test.

Run the math before you decide

The decision comes down to a simple comparison: do your savings (lower interest, consolidated debt) exceed your costs (penalty, legal and appraisal fees) over the time you'll keep the new mortgage? Work it out with the HOMEH refinance calculator, and ground your decision in how mortgages work in Canada and fixed vs variable mortgage rate.
