When you’re upsizing, downsizing, or chasing a new school catchment, the hardest part often isn’t finding the next place — it’s lining up the finances between selling your current home and buying the new one. In British Columbia, two tools can make that transition smoother: mortgage portability and bridge financing. They solve different problems, and the one that fits you best depends on timing, equity, and lender rules.

Below is a practical guide — written for BC homeowners — to help you compare both options confidently.

What Is Mortgage Portability?

Mortgage portability lets you move (port) your existing mortgage — same lender, remaining term, and (often) most contract features — from your current home to your new one. Think of it as taking your existing mortgage “with you,” instead of breaking it and starting over.

How portability typically works

• Apply to re-qualify. Portability isn’t automatic; lenders reassess income, debt, and credit under current underwriting guidelines.

• Match timelines. Your sale and purchase usually need to close within a lender-defined window (often within 30–120 days).

• Port and increase (or decrease).
  • If your new home costs more, you may port the existing balance and add new funds. Lenders often use a blend-and-extend approach, combining your existing rate with a rate on the top-up amount and setting a new (or extended) term.

  • If your new home costs less, some lenders allow a port and decrease; others may charge a partial prepayment penalty on the amount you’re paying down.

• Fees and penalties. If everything lines up within the portability window, you can often avoid or reduce a full mortgage prepayment penalty.

Pros of portability

• Penalty relief. Keep much (or all) of your existing term without paying a full breakage cost.

• Rate advantage. If your existing rate/term is favourable, portability preserves it.

• Continuity. You stay with the same lender and product features you already know.

Cons of portability

• Rules vary by lender. Not all mortgages are portable, and policies differ (including timelines and “decrease” rules).

• Re-qualification required. You must meet current lending standards — which can be tougher than when you first qualified.

• Tight scheduling. If closing dates don’t align, portability may fall through, triggering penalties anyway.

When portability shines

• You’re moving within your term and want to avoid penalties.

• Your existing rate and features are attractive.

• Your sale and purchase close within the lender’s timeframe.

• You’re qualifying comfortably under current guidelines.

What Is Bridge Financing?

Bridge financing is a short-term, interest-only loan that covers the gap between buying your next home and receiving sale proceeds from your current one. It’s about timing, not replacing your mortgage.

How bridge loans typically work

• Firm sale required. Most lenders require an unconditional (firm) sale on your current home to approve the bridge.

• Short term. Commonly a few days to a few months (enough to “bridge” between closings).

• Interest-only cost. You pay interest on the borrowed bridge amount until your sale completes and the bridge is repaid from proceeds.

• Secured against equity. The bridge uses the equity in your existing home that will be realized on sale.

Pros of bridge financing

• Schedule freedom. Buy first (when the right property appears) and sell after, without forcing same-day closings.

• Stronger offers. You can write a clean offer without a “subject to sale” clause, which can be decisive in competitive BC markets.

• No change to main mortgage (yet). Your existing mortgage can remain intact until everything settles.

Cons of bridge financing

• You pay interest and fees. Short-term rates are typically higher than standard mortgage rates, plus set-up or legal fees may apply.

• Not always available. Some lenders don’t offer bridge loans, or they cap amounts and durations.

• Requires a firm sale. Without one, options are more limited and may involve alternative lenders or different strategies.

When bridge financing shines

• You’ve found your next home before your sale completes.

• You have sufficient equity in your current home.

• You need flexible timing to avoid rushed closings.

• Market conditions favour strong, non-contingent offers.

Portability vs. Bridge: A Simple Decision Framework

Ask yourself:

1. Do my sale and purchase close within the lender’s porting window?
   • Yes: Portability may reduce/avoid penalties and keep your rate.

   • No: Consider bridge financing or a different sequencing plan.

2. Is my current rate worth keeping?
   • Yes: Portability (or blend-and-extend) can preserve it.

   • No or unsure: Compare the total cost of breaking now (penalty + new rate) to porting.

3. Do I have a firm sale on my current home?
   • Yes: Bridge financing becomes more accessible.

   • No: Portability still might work if dates match — otherwise, consider conditions or timing changes.

4. Am I qualifying easily under today’s rules?
   • Yes: Porting and topping up is more straightforward.

   • Tighter file: Explore lender options, alternative structures, or timing that supports approval.

5. Is my new home more expensive or less?
   • More: Expect port and increase with a blended rate on the top-up.

   • Less: Confirm whether your lender allows port and decrease without harsh penalties.

Real-World BC Scenarios

Scenario A: The clean port
You sell a condo in Langford and buy a townhome in Saanich closing two weeks later. Your lender’s portability window is 30–90 days. You re-qualify, dates align, and you port the mortgage, avoid a big penalty, and blend for the small top-up you need. Win.

Scenario B: Buy first, sell later
You spot the perfect family home in North Saanich and write a successful offer before selling your current place in Victoria. You secure a bridge loan against the equity you’ll realize on sale, cover the down payment and closing funds, and repay the bridge once the condo sale completes.

Scenario C: Downsizing with a gap
You’re moving from a detached home in Oak Bay to a smaller condo in James Bay. The purchase completes 45 days after the sale. Your lender allows port and decrease. You port the mortgage and pay a small partial penalty on the difference — but it’s still cheaper than breaking the entire mortgage.

Costs to Watch (and How to Compare)

• Prepayment penalties: If portability fails or you choose to break, penalties can be significant; compare them against the savings of a better new rate.

• Bridge interest and fees: Short-term interest accrues only on the bridge amount; add any lender or legal fees to your cost comparison.

• Legal and appraisal fees: Porting, bridging, or switching lenders can each trigger different third-party costs.

• Insurance considerations: If your mortgage is insured, confirm how portability impacts the premium or rules.

• Property Transfer Tax & closing timelines (BC-specific): Coordinate dates carefully; bridge loans can reduce stress around same-day funds.

Tip: Don’t just compare rates — compare total cost of ownership over your remaining term, including penalties, interest, and fees. A slightly higher rate that avoids a huge penalty can still be the cheaper move.

How GLM Mortgage Group Helps

• We map your dates. Aligning sale/purchase timelines is half the battle. We structure closings to fit lender portability windows or to make a bridge feasible.

• We shop lender policies. Portability and bridge rules vary widely. We compare multiple lenders to match your scenario (including port-and-decrease, blend-and-extend, or larger bridge limits).

• We stress-test scenarios. Port vs. break, bridge vs. subject-to-sale — we model the total dollars so you can decide with confidence.

• We quarterback the team. We coordinate with your realtor and lawyer/notary to minimize last-minute surprises.

Quick Takeaways

• Portability is best when dates line up and you want to preserve your current rate/term while avoiding large penalties.

• Bridge financing is best when you buy before you sell and need flexibility — assuming you have a firm sale and enough equity.

• Policies differ by lender, and both options require careful timing and re-qualification.

• The right choice depends on dates, equity, and total cost, not just rate.
