What is Porting a Mortgage?
Porting a mortgage is the process of transferring an existing mortgage, including its interest rate and terms, from one property to another when a homeowner moves.
Why Porting a Mortgage Matters in Real Estate
In Canada, many mortgages are portable, meaning they can be moved from one property to another without incurring early prepayment penalties. This is particularly beneficial when interest rates are lower on the original mortgage than current market rates.To port a mortgage, the homeowner must:
- Sell their existing property
- Purchase a new property within a specified timeframe
- Meet lender approval for the new home and mortgage amount
Not all mortgages are portable, and rules vary by lender. Buyers should confirm porting eligibility before making relocation decisions. Timing is crucial, as porting typically must be completed within 30 to 120 days of the original home’s sale.
Understanding mortgage portability allows homeowners to retain favourable rates, reduce penalties, and maintain continuity when upgrading or relocating.
Example of Porting a Mortgage in Action
A homeowner sells their condo in Calgary and buys a detached home. They port their 2.9% mortgage rate to the new property, avoiding higher market rates and penalty fees.
Key Takeaways
- Allows mortgage transfer between properties.
- Helps avoid prepayment penalties.
