Why banks count on you not shopping
Banks know that most renewal-era borrowers are busy, mortgage-fatigued, and inertia-driven. The renewal letter looks like an administrative form rather than a sales decision. The rate offered is usually within sight of competitive — close enough to feel reasonable, far enough that switching elsewhere would save you real money.
This dynamic is well-known in the industry and reflected in retention metrics. Banks earn substantial margin on renewal portfolios specifically because shopping rates are low.
The cure is simple: get a competitive quote from a broker, decide whether to switch or stay, and treat your renewal as a financial decision rather than a paperwork task.
How the renewal process works
Your lender is required by federal regulation to send you a renewal notice 21+ days before maturity. That notice will state your current balance, the renewal rate they're offering, and the term options available.
Once the term ends, your mortgage moves to whatever option you've signed (or to an open mortgage at posted rates if you don't sign anything, which is the worst outcome).
Best practice: start shopping 60-120 days before maturity. Rate holds from competing lenders typically protect you for 90-120 days, which gives you negotiating leverage with your existing bank and a fallback if they don't move.
Switching at renewal
Renewals are the cheapest time to switch lenders. Your current mortgage is maturing, so there's no break penalty. The new lender will absorb most or all of the switch costs (appraisal, legal, discharge fees) as part of their effort to win your business.
The process is straightforward. You apply with the new lender, they approve you, your lawyer (or theirs, paid by them) handles the discharge from your old lender and registration with the new one. The whole thing happens in 2-4 weeks and you experience zero out-of-pocket cost in most cases.
What you give up by switching: any relationship benefits with your existing bank (rare in mortgage), any rate discounts tied to bundled banking products (sometimes meaningful), and the convenience of staying with one institution.
Negotiating with your existing bank
If you bring in a competing offer, your existing bank will often match or get close. Their first offer is rarely their best — it's an opening position, expecting a counter.
The most effective approach: get a real written quote from a broker, then call your bank's mortgage retention specialist (not just the branch). Mention the competing offer. They'll usually come back with a better rate within 24 hours.
Be willing to actually switch. If your bank knows you'll never leave, their leverage is unlimited. The quote from the broker has to be a real backup option, and you have to be psychologically ready to accept it.
When refinancing makes sense at renewal
Renewal time is the cleanest moment to also refinance — pull out equity, consolidate debt, change the amortization, or remove a co-signer. There's no break penalty, and the legal/admin work is happening anyway.
Common refinance-at-renewal moves: consolidating $30,000-$80,000 of credit card and consumer debt into the mortgage at a much lower rate, pulling $50,000-$150,000 of equity for a renovation, removing an ex-spouse from title following a divorce, or extending the amortization to free up cash flow.
If any of these apply, mention them when you get your renewal quote — the broker can structure the deal to combine renewal and refinance into one transaction.
