Two clients called me last week about their renewals.

The first — her mortgage was coming up in a few months, and her bank had sent the standard renewal letter. She looked at the rate on it and almost panicked. It was noticeably higher than what she was paying.

She was about to sign it anyway — just to get it over with.

What she didn’t know is that the rate on that letter isn’t the bank’s real offer. It’s their opening number. If she’d called or gone online, she would’ve found a significantly better rate waiting for her — one the bank was always willing to give, but wasn’t going to volunteer.

A huge percentage of homeowners sign that first letter without ever discovering the second offer exists. That’s the trap.

The second client called the same day. He did know to push back, and his bank came down to a competitive number. After I ran the comparison, switching lenders wouldn’t have made sense for him — the savings didn’t justify the time. I told him to stay put.

Two homeowners. Same week. Same question. Completely different answers.

Your Bank Is Counting on Convenience

Here’s what most homeowners don’t think about: your existing lender has a built-in advantage at renewal. They have zero cost to retain you as a client. No underwriting staff reviewing a new application. No legal department processing a new file. No appraisal to order. They just keep collecting your payments.

A new lender picking you up has real costs — staff to review your file, lawyers to register the mortgage, systems to set up. They’re spending money to earn your business.

So logically, your existing lender should always have the best offer. They don’t have those acquisition costs to cover. They should be able to beat — or at least match — anything else on the table.

And sometimes they do — but only after you push past that first letter. The initial renewal offer is almost never their best. Banks know that a large chunk of homeowners will sign and return it without questioning it. If you call, if you mention you’re shopping around, a better rate appears. It was always there. They just weren’t going to lead with it.

What Switching Actually Involves

Let’s talk about what “switching” means, because the paperwork is what scares most people off.

If you move your mortgage to a new lender at renewal, you’ll need to go through income and employment verification, pass the mortgage stress test, potentially get an appraisal, and have a lawyer handle the discharge and registration.

It’s not nothing. It takes a few weeks and some coordination. But here’s what a lot of homeowners don’t realize: if you’re keeping the same loan amount and amortization — a straight transfer — the new lender often covers the legal and transfer costs. They want your business badly enough to absorb those fees.

And the penalty? There is no penalty at renewal. Penalties only apply when you break your mortgage mid-term. At maturity, you’re free to go wherever the best deal is. That’s your window — and it’s the one time your bank has no leverage over you.

When Staying Makes Sense

I’m a mortgage broker, so you’d think I’d always push for the switch. I don’t.

The rate gap is small. If your bank’s retention rate is close to what’s available elsewhere — say a difference of 0.10% or 0.15% — that’s a few hundred dollars a year. Real money, but it might not be worth the time if your situation is straightforward.

Your current product has features you’d lose. Some lenders offer generous prepayment privileges, portability, or flexible payment increases. Switching to a cheaper rate on a rigid product might cost you down the line if your plans change.

Your situation has changed. If your income has dropped, you’ve gone self-employed, or your credit has taken a hit since you first qualified, requalifying with a new lender might not go smoothly. Your existing lender doesn’t re-underwrite you at renewal — they just roll you over. That’s a real advantage when your file isn’t as clean as it was five years ago.

When Switching Is Worth It

Switching isn’t always about chasing a lower rate. Sometimes it’s about getting a mortgage that actually fits your life.

The rate gap is real. On a $500,000 mortgage, a 0.40% difference saves you roughly $2,000 a year — $10,000 over a five-year term. And if the new lender covers the transfer costs on a straight switch, there’s almost nothing coming out of your pocket on day one.

You need a different product. Your current lender might not offer the prepayment flexibility you need, or portability if you’re planning to move. Some lenders cap prepayment privileges at 10%; others allow 20%. That difference matters when you come into extra money and want to put it toward your mortgage.

You want to restructure. Renewal is the one penalty-free window to change your mortgage — adjust your amortization, add a HELOC, consolidate debt, or switch from fixed to variable. A new lender might offer a structure your current one can’t or won’t.

Your lender just isn’t the right fit anymore. Maybe their service has been poor. Maybe their digital tools don’t work for you. Maybe their policies have changed since you first signed up. A lender change at renewal is friction-free compared to breaking mid-term — this is the time to make that move.

The Broker Play

Here’s something I tell every client approaching renewal, whether they end up switching or not:

Get a competing offer before you do anything.

Even if you want to stay with your bank — even if their retention rate is decent — having an alternative changes the conversation. Your bank has a retention team that can go lower than what’s on that renewal letter. But they won’t volunteer their best number. That’s not how it works.

A broker’s job isn’t to convince you to switch. It’s to make sure you know what your options are — rate, product, structure, lender — so you’re negotiating from a position of strength. Sometimes I run the comparison and tell a client to stay put. Sometimes the switch makes sense for reasons that have nothing to do with rate. But in both cases, they made the decision with full information — not because they defaulted to convenience.

The Bottom Line

Your renewal is a financial reset. It’s the one moment in your mortgage cycle where you have full leverage — no penalty, no lock-in, total freedom to move. Don’t waste it by signing the first letter your bank sends you.

At minimum, start the conversation 120 days before your maturity date. That gives you enough time to get a rate hold, compare offers, and let your bank’s retention team respond — without feeling rushed.

If your renewal is coming up in the next four to six months, reach out. I’ll run the comparison — no obligation, no pressure. Just the numbers, side by side, so you can decide what’s actually worth it.
