Moving to a New Home? Here's What Happens to Your Existing Mortgage

Jen & Cory • November 11, 2026

Selling your home and buying another can be an exciting step, whether you're relocating for work, accommodating a growing family, or moving into a different stage of life.


But what happens if you still have several years remaining on your mortgage?


Many homeowners assume they must automatically break their existing mortgage and pay a penalty when they sell.

That isn't always the case.


Depending on your mortgage agreement, you may be able to transfer your existing mortgage to your new property through a process called mortgage porting.


What Does It Mean to Port a Mortgage?

Mortgage porting allows eligible borrowers to transfer an existing mortgage agreement from one property to another.

In some cases, you may be able to retain your current interest rate and remaining mortgage term.


This can be particularly valuable if your existing mortgage rate is lower than the rates currently available.


However, portability is not guaranteed. Your lender must approve the transaction, the new property, and your continued eligibility.


When Can Porting Your Mortgage Make Sense?

Consider a homeowner in Surrey who purchased a property three years ago and has two years remaining on a five-year fixed mortgage.


They now want to purchase a larger home in Langley.


If their mortgage is portable, they may be able to transfer the existing loan to the new property rather than automatically paying a penalty to break it.


Whether this is financially beneficial depends on the remaining mortgage balance, the rate available on new financing, and the lender's porting conditions.


What If You Need to Borrow More Money?

Moving to a more expensive property may require additional financing.


Some lenders offer blended mortgage arrangements that combine the existing balance at the original rate with new borrowing at a different rate.


The resulting rate and term depend on the lender's specific product.


It's important to compare this arrangement against other mortgage options rather than assuming that porting is always the least expensive solution.


What Could Prevent You From Porting?

Potential obstacles include:

  • Your existing mortgage does not include portability.
  • Your income or credit situation has changed.
  • The new property does not meet lender requirements.
  • Your sale and purchase dates fall outside the lender's permitted timeframe.
  • You need a financing structure the existing lender cannot provide.


Porting a mortgage also normally requires a new qualification review, even when you're staying with the same lender.


Should You Port or Break Your Mortgage?

The decision comes down to the total financial impact.


Before choosing, review the mortgage penalty for ending your current agreement, the interest cost of the available alternatives, and any fees associated with the transaction.


A lower interest rate on paper does not always produce the lowest overall borrowing cost.


Frequently Asked Questions

Can I port a fixed-rate mortgage?

Many fixed-rate mortgage products offer portability, but the specific terms vary by lender.


Can I port a variable-rate mortgage?

Some lenders permit it, while others impose different conditions or require an alternative arrangement.


Can I port my mortgage to a cheaper home?

Possibly. Reducing the mortgage balance may trigger additional conditions or partial prepayment penalties.


Final Thoughts

Moving homes doesn't necessarily mean starting your mortgage from scratch.


Before listing your existing property or committing to a new purchase, it's worth reviewing your mortgage contract and understanding your options.
