What Happens To My Mortgage When I Sell My Home?

When you sell your Toronto home, your existing mortgage must be paid off at closing, with possible penalties or options to transfer it to a new property.

Most homeowners in Toronto carry a mortgage, so it is natural to ask what happens when you sell. At closing, your lawyer uses the proceeds of the sale to pay off your remaining balance in full. Any outstanding property taxes, realtor commissions, and legal fees are also deducted before you receive your net proceeds. What happens next depends on your mortgage type and lender policies.

Key Scenarios Sellers Should Know

1. Mortgage Discharge
– If your term has ended or you have an open mortgage, the balance is paid out without penalty (other than a small discharge fee).
– For fixed-term mortgages, selling before the maturity date may trigger penalties. These can be the greater of three months’ interest or the interest rate differential (IRD). On a large loan, this can amount to thousands of dollars.

2. Mortgage Portability
– Many lenders allow you to “port” your mortgage to a new property. This means you can transfer the existing rate and terms to your next home.
– Porting can be attractive if your current rate is lower than today’s rates. However, you must typically buy your new property within a set time frame and meet the lender’s approval criteria.

3. Mortgage Blending
– If your new home is more expensive and you need a larger loan, some lenders offer a “blend and extend” option. This combines your existing mortgage rate with the new one, creating a blended rate for the higher balance.

4. Prepayment Penalties
– Sellers in Toronto often underestimate the significance of penalties. For example, on a $1.3 million east-end detached home with a $700,000 mortgage balance, breaking a fixed rate early could cost $10,000 to $20,000, depending on your lender and the term. Always confirm the numbers with your mortgage broker before listing.

Why This Matters In Toronto

With average condo prices around $700,000 and detached homes exceeding $1.5M (TRREB, 2025), your mortgage decisions directly impact your net proceeds. At Fox Marin Real Estate Team, we recommend that every seller review their mortgage terms early in the process. Understanding your options for discharging, porting, or blending helps you plan strategically for your next purchase or maximize take-home equity if you are downsizing.

Key takeaway: Your mortgage does not transfer automatically when you sell. It must be discharged, ported, or blended, and penalties may apply. Review your terms with a mortgage professional before listing your property to ensure you understand the details.
