How do I handle mortgage penalties when selling?
“Selling my Georgetown home — do I have to pay a huge mortgage penalty?” — Don’t panic. Read this first.
Quick, cut-to-the-chase answer
If you break a closed mortgage when you sell, your lender will charge a prepayment penalty. In Canada that penalty is usually the greater of three months’ interest or the Interest Rate Differential (IRD). For open mortgages there’s usually no penalty. The real cost shows up on your mortgage payout statement and comes out of your sale proceeds at closing unless you port the mortgage, get the buyer to assume it, or negotiate another solution.
This post shows exactly how to calculate the real cost, how penalties affect your net proceeds, what tax rules apply, and the practical moves Georgetown, Ontario home sellers should use to avoid surprises.
Why this matters in Georgetown, ON
Georgetown is a commuter town with strong buyer demand and rising prices. Sellers often want a fast close to capture market momentum. But speed costs: breaking a mortgage without planning can eat thousands off your sale proceeds and ruin your net return. Know your penalty options before you list. That knowledge puts you in control of pricing, negotiations, and closing dates.

What mortgage penalties actually are (short and clear)
- Closed mortgage: lender charges either three months’ interest or IRD — whichever is higher.
- Open mortgage: usually no penalty for early repayment.
- Variable-rate mortgages: penalties vary by lender; some use three months’ interest, others apply different calculations.
- Assumable mortgages: sometimes a buyer can take over your mortgage and avoid the penalty if the lender approves.
IRD (Interest Rate Differential) is the math lenders use when market rates are lower than your mortgage rate. It compensates the lender for lost interest over the remaining term.
Step-by-step playbook for Georgetown home sellers (do this now)
- Pull your mortgage contract and note: term end date, interest type (fixed/variable), current rate, remaining balance, and whether mortgage is closed or open.
- Call your lender and ask for a mortgage payout statement and a written breakdown of the prepayment penalty. Ask specifically: “How do you calculate the penalty if I sell on [planned closing date]?”
- Run the numbers: compare the penalty to the equity you expect to free up. If the penalty is small relative to your profit, proceed. If it’s large, don’t list until you have a plan.
- Explore alternatives:
- Port the mortgage to your next home (if the lender allows and you qualify). That keeps your rate and avoids penalty.
- Have the buyer assume the mortgage—only possible if the lender approves and the mortgage is assumable.
- Refinance to an open mortgage or break the mortgage early to minimize future penalties—but refinancing often carries costs too.
- Negotiate a price credit or seller-paid closing adjustment to cover the penalty.
- Add the penalty into your net proceeds worksheet and adjust your asking price or closing costs accordingly.
- Work with a realtor experienced in Georgetown (this is where local market timing and negotiation matter). They can advise on whether to price higher to cover a penalty or to structure buyer credits.
Real numbers example (practical)
Scenario: You owe $400,000 on a closed fixed-rate mortgage at 4.5% with 2.5 years left. Market mortgage rates dropped to 2.5%.
- Three months’ interest: 3 months × (4.5% / 12) × $400,000 ≈ $4,500.
- IRD: lender calculates the present value difference between your rate and current posted rate across remaining term — IRD in this case could be $8,000–$12,000 depending on lender formulas.
Result: You’ll likely pay the IRD (~$10k) because it’s higher than three months’ interest. That reduces your sale proceeds by that amount at closing unless you port or the buyer assumes your mortgage.
Tax and financial considerations (what your accountant will check)
- Personal residence: mortgage penalties are generally not tax-deductible for your primary home. The CRA does not allow deducting mortgage prepayment penalties against personal-use capital gains because most primary residences are capital-exempt anyway.
- Rental or investment property: mortgage penalties may be deductible as an expense against rental income or as an acquisition cost on sale — consult a tax accountant for proper treatment and documentation.
- Record everything: keep the payout statement and lender correspondence. If you claim any deduction related to a penalty (investment property), you’ll need clear records.

How mortgage penalties affect the sale process and timing
- Lenders produce a payout statement that’s valid for a short window (usually 30 days). If your deal slips past that date, the penalty can change.
- Closing funds need to cover outstanding principal + penalty + interest to the closing date. Your lawyer/notary will require proof of payout instructions.
- If you don’t plan for the penalty, the sale can stall at closing when funds are short. That’s a worst-case scenario — plan ahead.
Georgetown-specific negotiation moves and local market tips
- Use local demand to your advantage: in a seller’s market, build a penalty buffer into your asking price instead of taking a hit in closing costs.
- Porting is valuable here: many buyers in Georgetown are moving within Halton Hills or nearby GTA towns. If your next purchase is local, porting may be viable and simple to arrange.
- Assumable mortgages are rare, but if your mortgage is assumable it’s a bargaining chip. Some buyers will pay extra to inherit a below-market rate — use that in negotiations.
- Pick a realtor who knows local lenders and lawyers. Local agents understand how lenders in the Halton region calculate penalties and which lenders are flexible.
Who pays the penalty — seller or buyer?
Generally the seller pays the mortgage penalty because the mortgage is tied to the seller’s current loan. However, parties can negotiate otherwise:
- Buyer assumes mortgage (with lender approval) — buyer may take on mortgage and no penalty paid.
- Seller credits buyer at closing to cover the penalty — useful if buyer wants a lower monthly payment.
- Negotiated split — rare, but possible in tight deals.
What to ask your lender (script)
Be direct. Call and say:
- “I’m selling my home with a planned closing date of [date]. Please send a payout statement and a written breakdown of any prepayment charges and how they’re calculated for that date.”
- “Is this mortgage portable or assumable? If assumable, what’s the lender approval process and timeline?”
Keep written proof.

Quick checklist before you list (don’t skip these)
- Order your mortgage contract and recent statements.
- Request a payout statement with penalty breakdown dated for your expected closing.
- Confirm porting or assumption options.
- Run net proceeds with the penalty included.
- Discuss pricing and buyer credit strategies with your realtor.
- Confirm closing funds and lawyer instructions.
Final, practical advice — a direct roadmap
- Don’t list blind. Know your penalty cost first.
- If the penalty is small, list and sell. If it’s large, explore porting, assumption, or negotiating buyer credits.
- Get paperwork from your lender early. Use local experts — a Georgetown real estate agent and your accountant.
- Put the penalty on your net-proceeds worksheet and plan your next move accordingly.
