The renewal letter is a starting point, not the answer
Every few years your mortgage term ends and your lender sends a renewal offer. Most people sign it. That's understandable, but it means skipping the one moment when you can move lenders, change your structure and rethink your mortgage without paying a penalty.
What the renewal letter leaves out
A renewal offer is your current lender's opening position. It rarely shows what other lenders would offer, whether a different term would suit you better, or whether your mortgage could be set up to do more for you. Lenders know most borrowers renew without shopping, and the offer often reflects that.
Signing isn't wrong. Signing without comparing usually is.
Renewal, switch or refinance
These three get mixed up, but they're different. A renewal keeps your mortgage with the same lender for a new term. A switch moves the same balance and amortization to a new lender when your term ends, usually with no penalty. A refinance changes the mortgage itself, most often to borrow more against your home, consolidate debt or change the amortization, and it means qualifying again.
A refinance is generally limited to 80% of your home's value, including your current mortgage and anything you're consolidating.
Switching lenders got easier
Since November 21, 2024, borrowers who switch to a new federally regulated lender at renewal, keeping the same loan amount and amortization, no longer have to pass the mortgage stress test again. Before that, many uninsured borrowers felt stuck with their current lender simply because they couldn't requalify at a higher rate.
That change gives you real bargaining power at renewal. If another lender offers a better rate or a better structure, moving is now far more realistic.
When breaking early makes sense
You don't have to wait for renewal, but leaving early usually costs a penalty. On a variable-rate mortgage it's typically three months' interest. On a fixed rate, it's usually the greater of three months' interest or the interest rate differential, which depends on how rates have moved and on your lender's formula. Some lenders calculate it using posted rates, which can make it much larger.
Breaking early can still come out ahead, for example when it lets you clear high-interest debt, lock in a meaningfully lower rate, or set up a strategy that pays you back over many years. The only way to know is to work out the real penalty and compare it with what you'd save. Mitch can do that for you. The refinance calculator lays that out side by side.
The restructure opportunity
Renewal and refinancing are the cheapest times to change how your mortgage is built, not just its rate. That's when a regular mortgage can become a readvanceable one, which is the foundation for the Smith Manoeuvre, Rental Cash Damming and portfolio scaling. It's also the moment to choose a term length, prepayment privileges and portability that fit where your life is heading.
