30-Year Mortgages on Brand-New Homes: What Multiplex Buyers Should Know

Since December 15, 2024, buyers of brand new homes in Canada can stretch an insured mortgage over 30 years instead of 25. If you are shopping for a new multiplex unit in Greater Vancouver, this rule was written for a buyer exactly like you, and most people we talk to still do not know the details. Some do not know it exists at all.

The change matters because it lowers the monthly payment on the same loan. It also costs you real money over time, and anyone who tells you about the first part without the second is selling something. This post covers both, with the math shown.

To be clear about scope: everything here is about buying a single strata unit in a new multiplex with an insured mortgage, meaning a down payment under 20%. We have covered down payment rules and whole-building purchases separately; this post is about amortization length only.

What changed, exactly

In September 2024 the federal government announced what it called its biggest mortgage reforms in decades, effective December 15, 2024. The Department of Finance announcement and the regulations later published in the Canada Gazette made two changes that matter to multiplex buyers:

• 30-year amortizations on insured mortgages became available to two groups: all first-time home buyers (buying any home, new or resale), and all buyers of newly built homes, first-time or not.
• The insured price cap rose from $1 million to $1.5 million. Homes priced under $1.5 million can now be bought with less than 20% down, which covers the large majority of new multiplex units in Greater Vancouver.

Read that first point again, because it is the part buyers miss. You do not need to be a first-time buyer. If the home is brand new, you qualify for the 30-year option. A couple selling their condo to buy a new fourplex unit, or parents who have owned for twenty years buying into a multigenerational setup, are all eligible through the new-build door.

Who counts, in plain English

A new build

The regulation says the home must never have been occupied for residential purposes. For strata homes there is one sensible exception: a buyer living in the unit during the interim period before the strata paperwork completes does not spoil its new status. Every unit in a newly finished multiplex, and every pre-sale unit, fits this definition. A one-year-old unit being resold by its first owner does not.

A first-time buyer

You qualify if any of these is true: you have never bought a home in Canada; neither you nor your current spouse or partner owned a home you lived in during the past four calendar years; or your marriage or common-law relationship broke down and you have been living apart for at least 90 days. The definition is more generous than people expect. Someone who sold years ago and has been renting since may count as first-time again.

For readers of this site the distinction is mostly academic: buying a brand new multiplex unit qualifies you through the new-build route regardless of your ownership history. But if you are also weighing a resale home, only the first-time route gets you 30 years there.

The worked example: 25 versus 30 years

Here is the whole decision in one example. Our assumptions, stated up front: a $1,000,000 brand new multiplex unit, the minimum insured down payment of $75,000 (5% of the first $500,000 plus 10% of the rest), a 5-year fixed rate of 4.04%, which was the best advertised insured rate on August 14, 2026 according to Ratehub, and standard Canadian semi-annual compounding. Principal and interest only.

The base mortgage is $925,000. Mortgage insurance is added on top: 4.00% of the loan at this down payment level for a 25-year amortization, and 4.20% for 30 years, because insurers charge a 0.20 percentage point surcharge for the longer amortization, per CMHC's premium notice. So the loan is $962,000 over 25 years, or $963,850 over 30.

• 25-year amortization: about $5,081 per month.
• 30-year amortization: about $4,605 per month.
• Difference: about $476 per month, or roughly $5,700 per year.

We computed those payments ourselves from the inputs above. As a rule of thumb at this rate, every $100,000 borrowed costs about $528 per month over 25 years and about $478 over 30.

The trade-off, with the number attached

Nothing about the 30-year option is free. You are borrowing the same money for five more years, so you pay interest for five more years, plus the extra insurance premium, and you build ownership in your home more slowly.

To size it, run the same example to the end of the amortization. This is an illustration, not a prediction: it assumes the 4.04% rate holds for the entire life of the loan, and in reality you will renew at different rates every term. On that assumption, total interest comes to about $562,000 over 25 years versus about $694,000 over 30. The lower payment costs roughly $131,000 in extra interest over the life of the loan, plus the $1,850 larger premium financed at the start.

That number sounds brutal, and taken alone it argues for 25 years. But the comparison is not really 25 versus 30. It is 30 years versus not buying, or 30 years versus a smaller home, or 30 years now with faster payments later. Most lenders let you prepay 10% to 20% of the balance each year and raise your regular payment, so a 30-year mortgage can quietly become a 25-year one whenever your income allows. The reverse is not true: you cannot stretch a 25-year mortgage in a tight month without renegotiating.

Our honest position: take the 30-year option for the flexibility, then behave like you have the 25. Set the payment you can genuinely sustain, use prepayments in good years, and keep the lower required payment as the safety margin for bad ones. The buyers who get hurt are the ones who use the lower payment to buy more house than they can carry.

A few second-order effects worth knowing

• It can raise your maximum purchase. Lenders test your finances against the payment, and a 30-year payment is smaller, so some buyers qualify for a somewhat larger loan. Useful, but treat it as breathing room, not spending room.
• Pre-sales fit naturally. A pre-sale multiplex unit is by definition a new build, so the 30-year option will be on the table when your mortgage funds at completion, under whatever rates exist then.
• With 20% or more down, none of this applies. Uninsured mortgages could already run 30 years or longer at many lenders. The December 2024 change opened the long amortization to insured buyers, the ones putting down 5% to 19.99%.
• The $1.5 million cap is about the price, not the loan. The home's purchase price must be under $1.5 million for an insured mortgage. Above that, you need 20% down, full stop.

What this comes down to

• Since December 15, 2024, insured mortgages can run 30 years for all first-time buyers and for all buyers of new builds, per the Department of Finance and the Canada Gazette regulations.
• Buying any brand new multiplex unit qualifies you through the new-build route, whether or not you have owned before.
• The insured price cap is now $1.5 million, which covers most new multiplex units in Greater Vancouver.
• On a $1,000,000 unit with minimum down at 4.04%, the 30-year option lowers the payment by about $476 a month.
• The cost: a 0.20 point insurance surcharge and, if rates averaged 4.04% for the whole loan, roughly $131,000 more interest over the full amortization.
• Our advice: take the 30 for flexibility, prepay toward a 25, and never use the lower payment to justify a bigger price.

Frequently asked questions

What changed on December 15, 2024?

Two things, per the Department of Finance: insured mortgages can now amortize over 30 years for all first-time buyers and all buyers of newly built homes, and the maximum price for an insured mortgage rose from $1 million to $1.5 million. Both apply to insurance applications received on or after that date.

Do I need to be a first-time buyer to get a 30-year mortgage on a new multiplex unit?

No. The regulations open 30-year insured amortizations to any buyer of a newly built home, regardless of ownership history. A brand new multiplex unit, including a pre-sale, is a new build. First-time status only matters if you want 30 years on a resale home.

Who counts as a first-time home buyer under these rules?

Per the Canada Gazette regulations: someone who has never bought a home in Canada, or who has not lived in a home they or their spouse owned in the past four calendar years, or who has been separated from a spouse or partner for at least 90 days after a relationship breakdown.

What counts as a newly built home?

A home never occupied for residential purposes. For strata units there is one exception: living in the unit during interim occupancy, before the strata transfer completes, does not remove its new status. Every unit in a new multiplex qualifies. A resale of a one-year-old unit does not.

Does the $1.5 million cap cover multiplex units?

In most cases, yes. The cap applies to the purchase price of the home, and the majority of new duplex, triplex, and fourplex units in Greater Vancouver price below $1.5 million. A unit at or above the cap requires a conventional mortgage with at least 20% down.

How much lower is the monthly payment with 30 years?

In our worked example ($1,000,000 unit, $75,000 down, 4.04% fixed), about $476 per month: roughly $4,605 versus $5,081. As a rule of thumb at that rate, each $100,000 borrowed costs about $50 less per month over 30 years than over 25.

What is the downside of the 30-year option?

More interest and slower equity. If the rate averaged 4.04% for the whole loan, our example pays roughly $131,000 more interest over 30 years than over 25. There is also a 0.20 percentage point insurance surcharge. The lower payment is a tool, not a discount.

How much is the insurance surcharge for 30 years?

Insurers add 0.20 percentage points to the mortgage insurance premium when the amortization runs past 25 years, per CMHC's premium notice. At the minimum down payment that means 4.20% of the loan instead of 4.00%, about $1,850 more on a $925,000 mortgage, usually added to the loan.

Does a 30-year amortization help me qualify for a bigger mortgage?

Somewhat. Lenders test whether you can carry the payment, and the 30-year payment is smaller, so the same income can support a somewhat larger loan. How much larger depends on your full file and the qualifying rules, which are a separate topic. Use any extra room cautiously.

Can I pay a 30-year mortgage off faster?

Yes. Most lenders allow annual prepayments of 10% to 20% of the original balance and let you increase your regular payment. Used consistently, those privileges shrink a 30-year amortization toward 25 or less, while the lower required payment stays available as a cushion in expensive years.

I am buying pre-sale. Does the 30-year option apply to me?

Yes. A pre-sale unit has never been occupied, so it is a new build under the regulation. Your mortgage funds near completion, and the 30-year insured option will be available then, priced at whatever rates exist at that time. Confirm eligibility with your lender as completion approaches.

Does any of this matter if I have 20% down?

Not really. With 20% or more down your mortgage is uninsured, and lenders were already free to offer 30-year amortizations on those loans. The December 2024 change matters for insured buyers, those putting down between 5% and 19.99% on a home under $1.5 million.

The 30-year option makes brand new homes reachable for families the old rules priced out, and new multiplex units are exactly the homes it points at.
