Yes. A 30-year insured mortgage may be available in Alberta when at least one borrower is a first-time homebuyer or the property is a newly built home that has not previously been occupied.
That second part is important: you do not necessarily have to be a first-time buyer if you are purchasing a qualifying new build.
A 30-year amortization can reduce the required monthly mortgage payment, but it normally means paying more interest and building equity more slowly. Buyers should compare both options before deciding that the lower payment is the better long-term choice.
Who Can Qualify for a 30-Year Insured Mortgage?
Under CMHC Home Start, a borrower may qualify through either of these routes:
At least one borrower is considered a first-time homebuyer; or
The property is newly built and has not previously been occupied as a residence.
The property must also:
Be intended for owner occupancy
Be located in Canada
Be suitable for year-round occupancy
Have a purchase price or lending value below $1.5 million
Be financed with a high-ratio mortgage, meaning the mortgage exceeds 80% of the property’s lending value
The maximum amortization available through CMHC Home Start is 30 years.
What Is a First-Time Homebuyer?
For this mortgage-insurance program, you may be considered a first-time homebuyer if you meet at least one of the following conditions:
You have never purchased a home in Canada.
During the current calendar year and previous four calendar years, you did not occupy a Canadian home owned by you or your current spouse or common-law partner.
You have lived separately from your spouse or common-law partner for at least 90 days because of a relationship breakdown and meet the applicable timing requirements.
These definitions are specific to the mortgage-insurance program. Other programs—including the FHSA, Home Buyers’ Plan and First-Time Home Buyers’ GST/HST Rebate—have their own eligibility rules.
Can a Repeat Buyer Get a 30-Year Mortgage on a New Build?
Potentially, yes.
A repeat buyer may qualify when purchasing a home that is newly built and has not previously been occupied for residential purposes. That could include a newly completed detached home, duplex, townhouse or condominium that meets the insurer and lender requirements.
For a new condominium, CMHC makes an exception for certain periods of interim occupancy before the condominium declaration is registered or before the buyer formally takes possession.
This makes the program relevant not only to first-time buyers but also to existing homeowners moving into new construction.
How Much Down Payment Is Required?
For an owner-occupied property containing one or two units, the minimum equity requirements are generally:
5% of the first $500,000
10% of the portion above $500,000
For example, the minimum down payment on a $700,000 home would be:
5% of the first $500,000: $25,000
10% of the remaining $200,000: $20,000
Total minimum down payment: $45,000
Homes priced at $1.5 million or more are not eligible for CMHC mortgage insurance and generally require at least 20% down.
Mortgage default insurance is normally required when the down payment is less than 20%. The insurance protects the lender—not the homebuyer—and its premium is typically added to the mortgage.
How Much Can a 30-Year Mortgage Lower the Payment?
Here is a simplified illustration using a $450,000 mortgage and a 4.5% interest rate:
In this example, the 30-year amortization lowers the payment by approximately $222 per month, but adds approximately $69,641 in interest if the same interest rate continued for the entire amortization.
This illustration excludes mortgage-insurance premiums, property taxes, utilities and other ownership costs. Canadian mortgages are renewed periodically, so the actual interest paid will depend on future rates, payment changes and how quickly the mortgage is repaid.
Does Mortgage Insurance Cost More With a 30-Year Amortization?
It can.
CMHC’s published Home Start premiums are slightly higher than its standard 25-year CMHC Purchase premiums at comparable loan-to-value levels.
For example:
The premium is a one-time mortgage-insurance charge that can generally be added to the insured mortgage amount.
Other mortgage insurers and lenders may have different products, requirements and premiums. Ask your mortgage professional to compare the complete cost—not just the monthly payment.
Will a 30-Year Amortization Help Me Qualify?
A longer amortization produces a lower scheduled mortgage payment, which may improve affordability calculations. It does not eliminate the mortgage stress test or guarantee approval.
For CMHC Home Start, the published maximum debt-service ratios are:
Gross Debt Service ratio: 39%
Total Debt Service ratio: 44%
The qualifying calculation uses the greater of:
The contract mortgage rate plus 2%; or
5.25%
At least one borrower or guarantor must generally have a minimum credit score of 600, although the lender and insurer will consider the entire application.
Income, existing debts, property taxes, heating costs, condominium fees, down payment and credit history can all affect approval.
Is a 30-Year Mortgage Better Than a 25-Year Mortgage?
It depends on the buyer’s priorities.
A 30-year amortization may be helpful when:
A lower required payment creates needed monthly flexibility.
The buyer is purchasing a new build and expects additional expenses after possession.
The buyer plans to make extra payments when their budget permits.
The lower payment helps keep total housing costs manageable.
A 25-year amortization may be better when:
The buyer can comfortably afford the higher payment.
Paying less total interest is the priority.
The buyer wants to build equity faster.
The slightly lower mortgage-insurance premium is meaningful.
The safest approach is to compare the payment, insurance premium and long-term interest under both options.
Can You Combine a 30-Year Mortgage With the New GST Rebate?
Potentially, yes.
The 30-year insured-mortgage rules and the First-Time Home Buyers’ GST/HST Rebate are separate programs. A qualifying first-time buyer purchasing a qualifying new home may be eligible for both.
Under the GST rebate, eligible first-time buyers may recover up to 100% of the federal GST paid on a qualifying new home valued at $1 million or less, to a maximum rebate of $50,000. A partial rebate may be available between $1 million and $1.5 million.

Questions to Ask Before Choosing a 30-Year Mortgage
Ask your mortgage professional:
Do I qualify because I am a first-time buyer, because the home is newly built, or both?
What will my mortgage-insurance premium be?
How much will the 30-year option reduce my monthly payment?
How much additional interest could I pay?
Can I make lump-sum or increased payments without penalties?
What rate and payment should I prepare for at renewal?
How will property taxes, condominium fees and heating costs affect qualification?
Can I combine this financing with the new-home GST rebate, FHSA or Home Buyers’ Plan?
Buying a New-Construction Home in the Edmonton Area?
Financing is only one part of a new-build purchase. Buyers should also understand the builder’s specifications, upgrade pricing, deposits, construction timeline, GST treatment, closing adjustments, inspection rights and warranty coverage.
With more than 20 years of residential construction experience, I help buyers compare these details when purchasing new homes in Edmonton, Sherwood Park, Fort Saskatchewan, Devon, Spruce Grove and Stony Plain.
