Remember when you snagged that sweet 2.49 % five‑year fixed back in 2023? Now you’ve found a new place, but today’s rates start with a “4.” Porting lets you bring yesterday’s bargain rate along for the ride—and avoid the dreaded break‑fee detour. Here’s how to cross the finish line with your wallet (and sanity) intact.
1. What “porting” really means
Think of a portable mortgage like a suitcase: you pick it up from House A and set it down at House B. In practice, your lender lets you transfer the existing rate, term, and balance to the new property, so long as you close both deals within a set window (usually 30‑120 days). rocketmortgage.caSpring Financial
2. The three flavours of porting
| Option | Best for | How it works |
|---|---|---|
| Straight port | Buying a similar‑priced home | You keep the same balance and term—no changes, no fuss. |
| Port + increase | Upsizing | Need a bigger mortgage? Your lender “tops up” the difference at today’s rate, then blends the two into one payment. |
| Port + decrease | Downsizing | Paying down the balance is allowed, but many lenders cap the pre‑payment (often 10 %). Check the fine print. |
3. Timing pitfalls to dodge
- Bridge gaps carefully. Your lender may insist both closings happen within that short window, so line up movers, lawyers, and bridge financing (if needed) early.
- Mind the appraisal. The new place still has to meet your lender’s value criteria—especially if you’re borrowing more.
- Stay credit‑clean. Any big new loans (hello, pickup truck) between sale and purchase can derail approval.
4. Rate outlook: worth the hassle?
Economists still expect two BoC cuts before year‑end, but the July 30 decision was another hold. If you already have a rate in the low‑three‑per‑cent range, porting usually beats starting fresh—especially if you’re only halfway through your term.
5. Step‑by‑step port checklist
- Call your lender first—confirm porting rules, fees, and timelines.
- Get the numbers. Ask for a written breakdown of any top‑up blend rate or penalties if timing slips.
- Pre‑approve the difference. If you’re upsizing, secure underwriting on the top‑up amount.
- Coordinate closings. Your lawyer handles the paperwork, but you control the calendar.
- Final sign‑off. On possession day, your old mortgage balance shifts to the new title—no break fee, no new stress test.
Bottom line: Porting isn’t always smooth, but it can save thousands in penalties and higher interest. If you’re eyeing a move, let’s chat early and map the cleanest route.
