If you’re thinking about buying a new home but already have a mortgage with a great interest rate, you may have heard the term “porting your mortgage.” It’s one of the most overlooked options available to homeowners, yet it can potentially save you thousands of dollars.
Here’s what you need to know.
What Does It Mean to Port a Mortgage?
Porting a mortgage means transferring your existing mortgage—including your current interest rate and remaining term—from your current home to a new property.
Instead of breaking your mortgage and starting over, you may be able to take your existing mortgage with you.
For homeowners with rates that are lower than today’s market rates, this can be a significant financial advantage.
Why Would You Port Your Mortgage?
There are several reasons why porting may make sense:
Keep Your Existing Interest Rate
If your current mortgage rate is lower than what’s available today, porting allows you to continue benefiting from that lower rate for the remainder of your mortgage term.
Avoid Prepayment Penalties
Breaking a mortgage before the end of the term can result in substantial penalties—sometimes thousands of dollars. Porting your mortgage may allow you to avoid or significantly reduce these costs.
Simplify Your Move
Keeping the same mortgage can make your financing more straightforward, especially if you’re happy with your current lender.
What Happens If You Need More Money?
Many homeowners purchase a more expensive home than the one they’re selling.
In this case, your lender may allow you to blend and extend your mortgage.
This means:
- Your existing mortgage balance keeps its current rate.
- The additional funds are borrowed at today’s interest rate.
- The lender blends the two rates together to create one new mortgage payment.
Every lender calculates blended rates differently, so it’s important to compare your options.
What If You’re Buying a Less Expensive Home?
If your new mortgage amount is smaller than your current mortgage balance, porting may still be possible. However, depending on your lender, you may need to pay a penalty on the portion of the mortgage that isn’t being transferred.
This is why it’s important to review the numbers before making a decision.
Not Every Mortgage Can Be Ported
Although many mortgages are portable, not all of them are.
Some common conditions include:
- You must qualify for the new mortgage based on your current income, debt, and credit.
- The new property must meet the lender’s guidelines.
- There are usually timelines that require the sale of your existing home and purchase of your new home to occur within a specified period.
- Certain mortgage products may not be portable.
Each lender has its own rules, so it’s worth checking before you list your home.
Should You Port or Start Fresh?
Porting isn’t always the best option.
Sometimes current mortgage products offer features or rates that make starting with a new mortgage the better financial choice—even if it means paying a penalty.
That’s why it’s important to compare:
- The cost of breaking your current mortgage.
- The savings from keeping your existing rate.
- Available rates from other lenders.
- Your long-term financial goals.
A complete mortgage analysis can help determine which option saves you the most money.
The Bottom Line
Every homeowner’s situation is different, and there’s no one-size-fits-all answer.
If you’re planning to move, don’t assume you need to break your mortgage. Porting may allow you to keep your existing rate, avoid costly penalties, and make your transition much more affordable.
