Porting lets you transfer your existing mortgage rate, balance and remaining term to a new home, which can avoid a prepayment penalty when you sell. Rules vary by lender: you usually must requalify, buy within a set window after selling, and if you need more money the extra is often blended at a current rate. Check your mortgage contract and speak to your lender before you list.
When porting helps
- You have a low fixed rate you want to keep.
- Breaking the mortgage would trigger a large penalty.
- You are buying and selling close together.
What to ask your lender
| Question | Why it matters |
|---|---|
| Is my mortgage portable? | Not all are, especially some low-rate or restricted products |
| How long between sale and purchase? | Windows vary by lender; missing it can mean paying the penalty |
| Do I pay the penalty first and get it refunded? | Some lenders charge then refund once the port completes |
| What if I need a bigger mortgage? | Extra is often blended at current rates (blend-and-extend or blend-to-term) |
| What if the new home is cheaper? | Paying down part of the balance may trigger a partial penalty |
You still have to qualify
Porting is treated like a new application for the new property: income, credit and the new home’s appraisal are reviewed, and the stress test applies to any new borrowing.
Know your sale price first
Your equity and new mortgage size depend on what your home sells for.

Market context
Recent local averages for comparison.
—
A range is a starting point.
A strategy is what sells.
This model doesn’t know that your neighbour’s identical semi went $80,000 over asking last month, or which two upgrades actually pay back in your area. That conversation is free and takes twenty minutes.
Alternatives to porting
If porting does not fit, compare paying the penalty against a better rate elsewhere, or bridge financing if buying first. See prepayment penalties and buying before you sell.

The takeaway
Porting can save a prepayment penalty by moving your existing mortgage to your next home, but you must requalify, meet your lender’s timing window and understand how extra borrowing is blended. Read your contract and align both closing dates before listing.
