Can I port my mortgage to another home?
Can I port my mortgage to another home? Here’s a blunt, step-by-step answer that will save you money and time.
Quick answer up front
Yes — you can often port your mortgage to another home in Milton, ON, but only if your mortgage contract allows portability and your lender approves the new purchase. Porting protects your interest rate and avoids some early-break penalties. It’s not automatic. You must qualify on the new property, clear title issues, and coordinate closing dates. If you don’t plan this, you could face penalties, higher rates, or cash shortfalls.
Why this matters in Milton’s market
Milton is a commuter hub with strong demand, limited inventory, and fast closings. Buyers and sellers here need every advantage. Porting your mortgage means you keep a low locked-in rate when rates are rising. For sellers in Milton, porting can remove the headache of timing the sale and purchase while protecting mortgage costs.

Portable mortgage vs. assumable mortgage — know the difference
- Portable mortgage: You keep your mortgage terms (rate, remaining amortization) and transfer them to a new property. Your lender must approve and you must qualify on the new property.
- Assumable mortgage: A buyer takes over the seller’s mortgage under the same contract. This is rare and depends on contract language and lender approval.
Most people mean porting when they ask, “Can I port my mortgage to another home?” This blog explains how porting works in Ontario and exactly what Milton homeowners need to do.
Step-by-step: How to port your mortgage in Milton (the practical playbook)
- Read your mortgage contract immediately
- Look for the word “portable” or “portability clause.” If you have a mortgage broker, call them now.
- Call your lender and get a portability pre-approval
- Lenders require proof you can qualify on the new property. Ask for a conditional portability approval in writing.
- Order a current mortgage statement and payout figures
- You’ll need the outstanding balance, maturity date, and any special instructions. This shows what stays and what must be paid down.
- Run the numbers for difference in property value
- If your new home costs more, you can: 1) add funds from the sale, 2) top up the mortgage at a (likely) new rate, or 3) use a short-term second mortgage. Ask the lender about a blended rate or top-up options.
- Check for liens and second mortgages on the property being sold
- Any liens must be resolved before closing. A local title search is mandatory. Sellers in Milton often carry second mortgages or HELOCs; these complicate porting.
- Align closing dates or arrange temporary bridging
- Lenders often require the sale and purchase to close within a specific window. If dates don’t match, arrange bridge financing or a temporary mortgage solution.
- Get legal advice and coordinate your lawyer
- Your real estate lawyer will need mortgage documents, lien searches, and payout figures. They’ll register the appropriate discharge and charge on title at closing.
- Confirm final approval and sign documents
- Porting requires final underwriting. Expect a property appraisal and documentation. Don’t assume verbal approvals are final.
Common roadblocks Milton homeowners face — and how to fix them
-
No portability clause: If your mortgage isn’t portable, you can either: 1) pay out early and face a penalty, or 2) arrange a new mortgage for the new home and use sale proceeds to discharge the old mortgage. Shop several lenders and brokers.
-
Qualification failure: If you don’t qualify on the new property (income, credit, debt service ratios), you need a co-signer, larger down payment, or a different financing structure.
-
Liens and second mortgages: Resolve these early. Sellers often carry home equity lines or private second mortgages. These require discharge or negotiated payoffs at closing.
-
Timing mismatch: Use bridge financing or negotiate closing date flexibility in your sell/buy agreements. A short-term mortgage can buy time.
Penalties and costs to watch for in Ontario
-
Prepayment penalty: If you break a non-portable mortgage, Ontario lenders commonly charge the greater of three months’ interest or the interest rate differential (IRD). IRD can be substantial if your rate is well below today’s.
-
Appraisal fees, legal fees, and portability administration fees: Expect costs for appraisal, legal registration, and admin fees. Add these to your cash flow plan.
-
Top-up rates: If you increase the mortgage amount when porting, the new portion may be at a different rate. Confirm blended rate calculations.

Practical examples — realistic Milton scenarios
Scenario A — You’re upgrading in Milton
You have a portable mortgage at 2.99% with five years left. You’re buying a larger Milton home. If the mortgage is portable, you can move the remaining balance to the new house and add funds for the difference. The lender will underwrite the new property and may require a small top-up at today’s rate.
Scenario B — You’re downsizing and buying cheaper
You can port the mortgage to the cheaper home and use surplus sale proceeds to pay down principal or close the mortgage. Check for penalties if you shorten amortization or change mortgage structure.
Scenario C — Mortgage not portable
You’ll likely face an IRD or three-month interest penalty. Compare penalty cost vs. benefit of current rate to determine whether to break or retain. In many Milton cases, buyers choose a short-term mortgage on the new home and refinance later.
Local tips for Milton sellers and buyers
-
Use local mortgage brokers. Milton lenders know local appraisal values and commute-driven demand. Brokers can often negotiate better top-up blends and bridge products.
-
Time your sale for seasonal peaks. Milton inventory moves fast; list in times when demand is high to reduce your time carrying two homes.
-
Communicate with your real estate lawyer early. Clearing liens and coordinating discharges avoids day-of-closing surprises.
-
Get a second opinion on penalties. Some lenders miscalculate IRD. Have your broker or lawyer review the payoff statement.
-
Consider assumable features. If your mortgage allows assumption, it can be a selling point — but it’s different from porting and requires lender sign-off.

FAQ — The focused answers Milton homeowners need
Q: Can every mortgage be ported to a new home in Milton?
A: No. Only mortgages with a portability clause can be ported. Lender approval and qualification on the new property are required.
Q: Do I keep the same interest rate when I port my mortgage?
A: Yes, the existing rate and terms transfer, but if you top up the mortgage you may pay a different rate on the additional amount. Ask about a blended rate.
Q: What happens to second mortgages or HELOCs when I port?
A: These must be cleared or renegotiated. Second charges can prevent a smooth port unless the secondary lender agrees.
Q: How long before closing do I start the porting process?
A: Start as soon as you list or accept an offer — ideally 30–60 days before closing. Early action prevents appraisal and legal delays.
Q: What’s the typical penalty if I can’t port and must break my mortgage?
A: In Ontario, lenders usually charge the higher of three months’ interest or the IRD. IRD can be large if your rate is below current market rates.
Q: Can a buyer assume my mortgage instead of me porting it?
A: Possibly, but assumption is different and requires lender permission and buyer qualification. Assumptions are less common than porting.
Q: Who pays the appraisal and legal fees for porting?
A: The borrower typically pays appraisal and legal fees. Some lenders charge portability administration fees.
Q: How do I check for liens on my Milton property?
A: Your lawyer will run a title search. Resolve any liens, tax arrears, or builder holds well before closing.
