Your Mortgage With You When You Move?
Mortgage Portability Explained: Can You Take Your Mortgage With You When You Move?
Selling one home and buying another can create many financial decisions, especially when you still have time remaining on your current mortgage term.
Many homeowners assume they must completely break their existing mortgage when they move. In some cases, however, the mortgage may be portable.
Mortgage portability may allow you to transfer your current mortgage from your existing property to a new one. Depending on the lender and the mortgage terms, this could help you keep part or all of your existing rate and avoid some of the costs associated with breaking the mortgage early.
Porting a mortgage can be valuable, but it is not automatic. The lender must still approve both the borrower and the new property.
What Does Mortgage Portability Mean?
Mortgage portability is a feature that may allow you to transfer your existing mortgage to a new property when you move.
The mortgage itself is not simply moved without review. The lender will usually need to approve:
• Your current income
• Your employment
• Your credit
• Your debts
• The new property
• The purchase price
• The amount of financing required
• The timing of the sale and purchase
If approved, you may be able to carry over the remaining mortgage balance, interest rate and term to the new home.
The exact process depends on the lender and the terms of your mortgage contract.
Are All Mortgages Portable?
No. Not every mortgage includes a portability feature.
Some mortgages are fully portable, while others may have restrictions. Certain low-rate or limited-feature products may not allow portability at all.
Before assuming your mortgage can be transferred, review:
• Your mortgage commitment
• Your mortgage contract
• The lender’s portability policy
• Any time limits
• Minimum or maximum transfer amounts
• Whether the new property is eligible
• Whether the mortgage can be increased
• Whether the current term must remain unchanged
A mortgage broker can help review these details before you list your home or make an offer on another property.
Why Might Porting a Mortgage Be Beneficial?
Porting may be useful when your current mortgage terms are more favourable than the options available today.
Potential advantages may include:
• Keeping your existing mortgage rate
• Avoiding or reducing a prepayment penalty
• Preserving the remaining term
• Reducing the cost of arranging new financing
• Maintaining a mortgage product that continues to suit your needs
This can be especially valuable when your current rate is lower than the rates available when you move.
Portability is not always the best choice, but it should be reviewed before the mortgage is broken.
What Happens If the New Home Costs More?
If the new property costs more than your current home, you may need a larger mortgage.
In that situation, the lender may allow you to port your existing mortgage and add new funds.
This is sometimes referred to as a blend and increase.
The lender may combine:
• Your existing mortgage balance at the current rate
• The additional mortgage amount at the lender’s current rate
The result may be a blended interest rate.
The exact calculation and available options will depend on the lender.
For example, if you have $250,000 remaining on your mortgage and need a total mortgage of $350,000 for the new home, the lender may port the original $250,000 and add $100,000 at current rates.
The final payment and interest rate would be based on the lender’s calculations and the remaining term.
What Happens If the New Home Costs Less?
If you are downsizing or purchasing a less expensive property, you may need a smaller mortgage.
Some lenders may allow a partial port, but the portion of the mortgage that is not transferred could be treated as an early repayment.
That may result in:
• A prepayment penalty
• Restrictions on how much can be reduced
• Changes to the mortgage structure
• Additional legal or discharge costs
The lender’s policy is important.
A portable mortgage does not always mean the entire mortgage can be reduced without cost.
Does Porting Eliminate the Prepayment Penalty?
Not always.
Some lenders may waive or refund the prepayment penalty if the mortgage is successfully ported within the required timeframe.
Others may require the penalty to be paid when the original property is sold and then reimburse some or all of it after the new mortgage closes.
There may also be conditions attached to the refund.
These may include:
• The new mortgage must close within a certain number of days
• The same borrower must remain on the mortgage
• The new mortgage must meet a minimum amount
• The new property must be acceptable to the lender
• The mortgage must remain with the same lender
• All documentation must be completed on time
It is important to understand the process before the sale closes.
Timing Is Critical
Portability usually comes with strict timing requirements.
The sale of your current home and the purchase of the new home may need to occur:
• On the same day
• Within a specific number of days
• Within a limited period set by the lender
If there is too much time between the sale and the purchase, you may lose the ability to port the mortgage.
This can become especially important when:
• You sell before finding another home
• You need temporary accommodations
• Construction of the new home is delayed
• The closing date changes
• The purchase transaction falls through
Before agreeing to closing dates, confirm the lender’s portability window.
You Still Need to Qualify
Having a portable mortgage does not guarantee approval on the new property.
The lender must still confirm that you qualify based on current information.
Your financial situation may have changed since the original mortgage was approved.
The lender may review:
• Employment and income
• Credit history
• Monthly debts
• Property taxes
• Heating costs
• Condo fees, if applicable
• Down payment
• Closing costs
• The value and condition of the new property
A homeowner who qualified several years ago may not automatically qualify for the same or a larger mortgage today.
The New Property Must Also Qualify
Mortgage approval involves both the borrower and the property.
Even if your current mortgage is portable, the lender may decline the transfer if the new property does not meet its guidelines.
Potential concerns may include:
• A low appraisal
• Major repairs
• Uninsurable conditions
• Unusual construction
• Rural or remote location
• Seasonal use
• Commercial activity
• Environmental concerns
• Condo corporation issues
• Limited marketability
Buyers should avoid removing financing conditions until the lender has reviewed the new property.
What Is a Blend and Extend?
Some lenders may offer a blend and extend option.
This may combine your existing mortgage rate with a new rate while extending the mortgage into a new term.
For example, the lender may:
• Keep part of the existing rate
• Blend it with the current rate
• Extend the mortgage into a new term
• Adjust the payment based on the new balance and amortization
This option may help borrowers avoid a full penalty, but it can also create a longer commitment.
Before accepting a blend and extend offer, review:
• The new blended rate
• The length of the new term
• Prepayment privileges
• Future penalty calculations
• Portability rules
• Total borrowing cost
• Whether better alternatives are available elsewhere
A blended rate should be evaluated as part of the complete mortgage structure, not simply compared with the current advertised rate.
Porting Versus Breaking the Mortgage
Porting is not always the best financial choice.
In some cases, breaking the existing mortgage and arranging new financing may provide better terms or greater flexibility.
A proper comparison should consider:
• The prepayment penalty
• The existing mortgage rate
• The available new mortgage rates
• Legal fees
• Appraisal costs
• Discharge fees
• Cashback repayment
• Mortgage features
• Prepayment privileges
• Portability
• The remaining mortgage term
• The total interest cost
A lower interest rate does not automatically mean the new mortgage will save money.
The full cost of changing the mortgage must be compared with the cost of porting it.
What If You Buy Before You Sell?
Buying a new home before your current home sells can create additional financing needs.
You may require:
• Bridge financing
• A larger temporary down payment
• Access to savings or investments
• A firm sale agreement on the existing property
• Careful coordination between the lender, lawyer and mortgage broker
Bridge financing may help cover the down payment on the new property until the sale of the existing home is completed.
It is generally intended for a short period and must be properly arranged in advance.
Portability and bridge financing are separate issues, but they may need to work together as part of the same transaction.
What If You Sell Before You Buy?
Selling first can reduce the risk of carrying two properties, but it may create timing challenges.
If you do not purchase another home within the lender’s portability period, you may lose the ability to transfer the mortgage.
You may also need:
• Temporary housing
• Storage
• A flexible closing date
• Short-term financing
• A larger deposit for the next purchase
Before selling, confirm how long your lender allows between transactions.
Can You Port a Mortgage to Another Province?
Some lenders may allow a mortgage to be ported to a property in another province, while others may have geographic restrictions.
The lender must be able and willing to lend in the province where the new property is located.
The transaction may also involve:
• Different legal processes
• Different property registration systems
• Different provincial taxes or fees
• Additional documentation
• Changes in insurance requirements
Borrowers planning an interprovincial move should confirm portability early.
Can You Change Lenders When Porting?
A mortgage can generally only be ported with the existing lender.
Moving the mortgage to a different lender would usually mean paying out the current mortgage and arranging new financing.
That may involve:
• A prepayment penalty
• Discharge fees
• New legal fees
• A new appraisal
• A new mortgage application
Even when the current lender allows portability, it may still be worthwhile to compare the porting option with other available mortgages.
Questions to Ask Before You Move
Before listing your home or making an offer, ask:
• Is my mortgage portable?
• How long is the portability window?
• Can I increase the mortgage?
• Can I reduce the mortgage?
• Will a penalty apply?
• Will the penalty be refunded?
• Can I keep my current rate?
• How will the blended rate be calculated?
• Does the new property qualify?
• Will I need an appraisal?
• Can I port to another province?
• What happens if the closing dates do not align?
• Is bridge financing available?
• Would breaking the mortgage provide a better overall result?
These answers can affect how you structure both the sale and the purchase.
Plan Before You List or Make an Offer
Mortgage portability should be reviewed before major decisions are made.
Waiting until the sale is firm or the new offer has been accepted may limit your options.
Before moving forward:
• Review the current mortgage contract
• Request a penalty estimate
• Confirm the lender’s portability rules
• Determine the mortgage amount needed for the new property
• Review your current income and debts
• Discuss possible closing dates
• Consider whether bridge financing may be required
• Compare porting with arranging a new mortgage
Early planning can help prevent unnecessary penalties, missed deadlines and financing complications.
