Renewing a 2021 mortgage in 2026: the payment jump and four ways to soften it

Updated November 13, 2026 · 780 words

Thousands of British Columbia homeowners locked in five-year fixed mortgages in 2021, when rates were under 2%. Many of them are renewing now at rates more than twice as high. The balance is lower than when they started, but the payment still jumps.

This guide follows one typical 2021 mortgage through its renewal, shows how much the payment changes at four renewal rates, and compares the main ways to soften it: stretching the amortization, prepaying, choosing a term, and switching lenders.

Desk Office — A renewal letter usually arrives about four months before the term ends. That's the time to shop.

The example mortgage

In 2021 a buyer took a $600,000 mortgage at 1.89% fixed for five years, amortized over 25 years. The monthly payment was about $2,509. After five years of payments, about $501,000 is left, with 20 years of amortization remaining.

Bar chart of a 2021 payment of $2,509 at 1.89% compared with renewal payments on the remaining $501,000 over 20 years: $2,899 at 3.49%, $3,027 at 3.99%, $3,159 at 4.49% and $3,292 at 4.99% — Even at 3.49%, the payment rises by $390 a month. At 4.99% it rises by almost $800.

Renewal rate	New monthly payment	Change from 2021
3.49%	$2,899	+$390 (+16%)
3.99%	$3,027	+$518 (+21%)
4.49%	$3,159	+$650 (+26%)
4.99%	$3,292	+$783 (+31%)

The payment rises less than the rate alone would suggest because the balance is $99,000 smaller. But on a household budget, a $500 to $800 monthly increase is real money.

Option 1: reset the amortization

Some lenders will let you renew over a longer amortization, bringing the remaining term back to 25 years, or 30 for some uninsured mortgages. That lowers the payment, but you pay interest for longer.

Bars comparing the monthly payment and total remaining interest at 4.49% on a $501,000 balance: $3,159 a month and $257,000 of interest over 20 years, $2,773 and $330,000 over 25 years, and $2,525 and $408,000 over 30 years — Resetting to 25 years brings the payment almost back to 2021 levels, at a cost of about $74,000 more interest over the life of the mortgage.

Remaining amortization	Payment at 4.49%	Total interest from here
20 years	$3,159	about $257,000
25 years	$2,773	about $330,000
30 years	$2,525	about $408,000

Stretching is a reasonable bridge if money is tight for a few years. It's an expensive habit if you keep doing it. Whether you can extend depends on the lender, whether the mortgage was insured, and your current income.

Option 2: prepay before and during the term

Most fixed-rate mortgages let you prepay 10% to 20% of the original balance each year without penalty, and increase the regular payment by a similar percentage. A lump sum just before renewal reduces the balance the new rate applies to.

Line chart of the balance over a new five-year term at 4.49%: about $414,000 at the next renewal with regular payments only, and about $360,000 with an extra $10,000 lump sum each year — $50,000 of prepayments over five years leaves the balance about $55,000 lower, because the prepaid money stops collecting interest right away.

Option 3: pick the term on purpose

At renewal you choose again between fixed and variable, and between terms from one to five years.

A five-year fixed rate gives certainty and suits a tight budget.
A shorter fixed term (two or three years) costs a little more today but lets you renew sooner if rates fall.
A variable rate moves with the Bank of Canada's policy rate. Most variable mortgages can be locked into a fixed rate later, and their prepayment penalty is usually just three months' interest.

Read the Bank of Canada's recent decisions before you choose. EstateBlock's Bank of Canada rate announcement page explains each decision and what it means for variable payments and BC home prices.

Notebook Desk — Write down your current balance, rate, prepayment privileges, and maturity date before you call around.

Option 4: switch lenders

Your current lender's renewal offer is rarely its best rate. Since November 2024, borrowers with uninsured mortgages who switch lenders at renewal, without increasing the loan or the amortization, no longer have to pass the stress test again. Insured mortgages already had that exemption. That makes a switch much easier for households whose incomes haven't kept up with rates.

Switching usually costs little or nothing: many lenders cover the legal and discharge fees. Start comparing about 120 days before maturity, when most lenders will hold a rate.

A renewal checklist

Note your maturity date. Lenders send the renewal letter about 21 days to four months before it.
Get two or three quotes from a broker and other lenders, not just the renewal offer.
Make any prepayment you can afford before the term ends.
Decide on the amortization deliberately, knowing the interest cost.
Don't let it auto-renew. If you do nothing, some lenders renew you into a term and rate you didn't choose.

Quick answers

Will I have to requalify at renewal? Not with your current lender. If you switch lenders and keep the same loan and amortization, you no longer have to pass the stress test.

Can I break my mortgage early to lock a rate? You can, but the penalty on a fixed mortgage can be large. Most lenders let you lock a renewal rate up to 120 days early without breaking anything.

Should I use savings to pay down the balance? If you have an emergency fund and no higher-interest debt, a prepayment at a 4% to 5% mortgage rate is a guaranteed, tax-free return.
