Can I transfer a mortgage to a new property?
Can I transfer a mortgage to a new property? Read this first — Milton sellers are using mortgage portability to move faster and cut penalty costs.
Why this matters if you’re selling a home in Milton, ON
Moving in Milton? Your mortgage is not a chain — it can be a tool. Many sellers assume they must pay a giant penalty or requalify for a new mortgage when they buy a new home. That’s false. In Ontario, and especially for Milton homeowners, mortgage portability, assumable mortgages, and smart strategies let you keep your rate, reduce costs, and close faster.
This guide tells you exactly when you can transfer a mortgage, when you can’t, how to do it, and how to pick the best path given Milton’s market and local lenders.
Short answer
Yes — sometimes. You can transfer a mortgage to a new property if your mortgage contract allows portability or if your lender approves an assumption. If neither is possible, you’ll need to refinance or negotiate a deal. The difference between saving thousands and paying a penalty often comes down to timing, product features, and lender rules.

Key terms — quick and useful
- Mortgage portability: Move your existing mortgage rate and terms to a new property.
- Assumable mortgage: A buyer takes over your mortgage and its terms.
- Break penalty: Fee for ending a fixed-rate mortgage early.
- Refinancing: Replacing an existing mortgage with a new one.
- Bridge loan: Short-term financing that covers the gap between buying and selling.
Who in Milton can port a mortgage?
Portability tends to be available for conventional mortgages with major banks and many credit unions. It’s most common when:
- You sell your current property and buy another within the portability window allowed by your lender. (Often 30–120 days; check your contract.)
- The new mortgage amount is equal to or less than your current mortgage. If you need more funds, you may be able to port and blend-and-extend or add a second mortgage.
- You meet the lender’s valuation and qualification requirements for the new property.
If you don’t meet these, an assumption or refinancing becomes the fallback.
Why portability often wins for Milton sellers
- Rate preservation: Interest rates have been volatile. Porting keeps your existing rate and avoids higher new-market rates.
- Lower penalties: Porting avoids break penalties tied to fixed-rate mortgage early discharge.
- Faster closing: No underwriting for a brand-new mortgage can speed the transaction.
In Milton, where competition for move-in ready family homes is high, speed and certainty win offers. Portability gives buyers and sellers a competitive edge.
When porting is NOT available
- Contract excludes portability. Some closed or specialized products disallow it.
- Time window is missed. Many lenders require you to buy within a set time.
- New property needs higher mortgage size beyond lender’s rules (may require blending or second mortgage).
- Lender refuses due to poor credit or change in borrower circumstances.
If porting is denied, you MUST compare the cost of breaking the mortgage (penalties + legal) vs refinancing at a new rate.

How to port a mortgage — step-by-step for Milton sellers
- Read your mortgage contract now. Look for the portability clause and the allowed window. Don’t wait.
- Call your lender and ask: Can I port? What’s the portability window? What documents are required for the new property? Ask for timelines in writing.
- Talk to your mortgage broker or local lender in Milton about blend-and-extend options if you need extra funds. This mixes your old rate with a new top-up rate.
- Arrange valuation for the new property quickly. Lenders often require appraisal or inspection for the new property.
- Coordinate closing dates. Porting typically requires aligned closings (sell and buy close within the portability period).
- If you can’t port, get penalty estimates and compare with current market rates. Include legal fees and discharge costs.
- Consider bridge financing if the buy closes before the sale. Milton’s local lenders offer short-term solutions.
Numbers matter: example scenarios
Example A — Port vs Break
- Existing mortgage: $400,000 at 2.49% fixed, term remaining 3 years.
- New mortgage needed: $380,000.
- Porting: Keep 2.49%, no break penalty. Minimal admin costs.
- Breaking: Penalty could be 3 months’ interest or an IRD (interest rate differential). Could cost $6,000–$12,000 depending on lender.
Example B — Port + Top-Up
- Existing mortgage: $300,000. New home needs $360,000.
- Lender allows porting $300,000 and a top-up $60,000 at market rates. You keep majority of your rate and only pay current market on the top-up. Often cheaper than breaking the full mortgage.
Local lender behaviour in Milton, ON
- Big banks: Usually offer portability but with strict valuation and timing rules.
- Credit unions and monoline lenders: May be flexible on blending and second mortgages.
- Mortgage brokers in Milton: Can find lenders who allow assumptions and creative port-and-top-up structures.
Pro tip: Use a mortgage broker local to Milton. They know which lenders approve porting quickly and who will value your new property favourably.
Assumable mortgages — a buyer-focused strategy for sellers
If you’re selling a home in Milton with an assumable mortgage, you can market that as a benefit. Buyers may get a lower rate by assuming your mortgage — a major selling point in a rising-rate market.
As a seller, making your mortgage assumable can increase buyer interest and shorten time on market. But lenders won’t allow assumption without buyer qualification.

Avoid common mistakes Milton sellers make
- Waiting until after listing to check portability. Do it before you list.
- Assuming all lenders allow portability — they don’t.
- Ignoring timing. Closing dates must be coordinated.
- Forgetting additional costs: legal fees, appraisal, discharge statements, and possibly a top-up at a higher rate.
Tactical checklist for Milton sellers — what to do this week
- Pull your mortgage agreement and find the portability clause.
- Call your lender for written confirmation of portability rules.
- Book a meeting with a Milton-based mortgage broker.
- Line up valuations for any properties you’re considering.
- Plan closing dates to fit the portability window.
Do these five things and you’ll avoid the most expensive mistakes.
When to choose refinancing instead
- Your mortgage has a huge penalty but current market rates are lower than your existing rate.
- You want to change lenders for better terms, cashback, or features.
- You need to borrow significantly more and lender won’t allow a top-up.
