Can You Port Your Mortgage When Downsizing? A Guide for Greater Victoria Homeowners

If you are selling your family home and buying a smaller one in Greater Victoria, one of the smartest questions you can ask is whether you can port your mortgage. Porting lets you move your existing mortgage to your new home instead of breaking it early, which can save you thousands in prepayment penalties and help you keep a rate you may no longer be able to match. This guide explains how mortgage porting works in British Columbia, when it is worth doing, and the questions to ask before you decide.

A note before we begin: mortgage rules vary by lender and by your specific contract. Treat this as a plain-language starting point, and confirm the details with your mortgage professional or lender before making any decision.

What does it mean to port a mortgage?

Porting means transferring your existing mortgage to a new property rather than paying it off and taking out a brand-new loan. The idea is straightforward: if you stay with the same lender and buy your next home around the same time you sell, the lender can carry over your current interest rate, your remaining balance, and the rest of your existing term to the new property.

The main benefit is avoiding the prepayment penalty you would otherwise owe for breaking your mortgage early. Because the mortgage is transferred rather than cancelled, the lender does not treat it as a payout, so the penalty is typically waived. For a fixed-rate mortgage with years left on the term, that penalty can amount to tens of thousands of dollars, so porting is often worth serious consideration.

Why porting matters for downsizers

Downsizing in Greater Victoria often means selling a long-held family home and buying a condo, townhome, or smaller house, sometimes at a lower price than what you sold for. That difference is exactly where porting can help. When you are borrowing less and moving within a short window, porting lets you keep your existing rate and term instead of locking into whatever rate is available on the day you buy.

• You keep your current rate. If today's rates are higher than the one you locked in years ago, porting preserves that lower rate.
• You avoid the early-break penalty. The amount that transfers to the new home typically does not trigger a penalty.
• You keep your amortization and term moving forward. You do not start the clock over as a brand-new borrower.

Port and increase vs. port and decrease

The size of your new mortgage relative to the old one changes how porting works.

Port and increase. If your next home costs more and you borrow more, the lender may let you add funds on top of the ported balance. The added amount is often priced at a blended rate, a weighted average of your old rate and today's rate, or at the new market rate. Some lenders require a minimum amount of time left on your term before they will blend.

Port and decrease. If, like most downsizers, you are borrowing less, only the amount that actually transfers avoids the penalty. The portion you pay down is treated as a prepayment, so you may owe a penalty on that difference. In practice this means the lower your new mortgage, the more of your old balance counts as a prepayment, which is a key detail to run the numbers on.

When porting does not make sense

• Your current rate is worse than today's market. If rates have dropped since you locked in, breaking and re-financing at a lower rate may beat keeping the old one, even after the penalty.
• Your mortgage is not portable. Some variable-rate and discounted fixed products exclude portability. Check your contract.
• Your timeline is too long. Lenders allow a limited window between selling and buying (commonly 30 to 120 days, depending on the lender). If your next home is far off, porting may not fit.
• You need a different lender. Porting requires staying with the same lender. If you want to switch for a better product, porting is off the table.

What porting requires of you

Porting is not automatic. It is a new agreement, so you will generally need to re-qualify, meaning income, credit, and a new appraisal of the property you are buying. If your situation has changed since you first got the mortgage, this step matters. A larger new purchase may also require a higher down payment, so your overall plan and your porting conversation should happen together.

Questions to ask your lender before you decide

• Is my current mortgage portable, and is portability written into my contract?
• What is the exact window of time I have between selling and buying to qualify?
• If I borrow less, how much of my balance counts as a prepayment, and what would the penalty be?
• If I borrow more, what rate applies to the added amount, and will it be blended?
• Do I need to re-qualify, and what documents will that take?
• Can you show me the porting option side by side with breaking and re-borrowing, including all penalties and costs?

Running these questions before you list your home means you will know exactly what your next purchase can look like. For many downsizers, that clarity is as valuable as the savings themselves.
