Buying a New Build in Alberta: The Financing Timeline
A new build closes on the builder’s schedule, not yours. Here is how a completion mortgage works, when a progress draw applies instead, and how to hold a rate against a possession date that can move.

How does financing a new build in Alberta differ from a resale purchase?
A resale purchase closes on one date you and the seller agree to, and your mortgage funds once at closing. A new build closes on a possession date the builder controls, which can move, so your financing has to account for a longer and less certain timeline between your offer and your first mortgage payment.
On resale, your lender underwrites once and funds once. On a new build, your lender underwrites early, sometimes more than a year before possession, then has to keep that approval valid until the builder actually hands over keys.
That gap is where most of the financing complexity on a new build lives. Everything else on this page follows from managing it.
The citable fact: New build financing in Alberta differs from resale mainly because the closing date is set by the builder and can move, which stretches the period a mortgage approval has to remain valid.
What is a completion mortgage?
A completion mortgage is a single mortgage that funds in one lump sum on the day the home is finished and possession is granted, the same way a resale mortgage funds at closing. It is the standard structure for a buyer purchasing a new home from a builder, whether a single detached home or a condominium unit.
You sign your mortgage documents and your lender advances the full amount once the builder has completed construction and the home is ready for possession. Until that day, no mortgage funds move and you make no mortgage payments.
The citable fact: A completion mortgage funds in a single advance on possession day, matching how a resale mortgage funds at closing.
What are progress draws and when do they apply?
Progress draws are staged advances of mortgage funds released as construction reaches defined milestones, most commonly used when a buyer owns the lot and is financing a custom or self-managed build rather than buying a finished unit from a production builder. Each draw is typically tied to an inspection confirming the stage of construction has been reached.
Progress draw financing is less common for a standard production-builder purchase, where a completion mortgage is the norm. It becomes relevant when you are financing the construction itself, not just buying a completed product.
| Feature | Completion mortgage | Progress draw mortgage |
|---|---|---|
| When funds advance | Once, on possession day | In stages, tied to construction milestones |
| Typical use case | Buying a finished home or unit from a builder | Financing a custom build on land you already hold |
| Inspections required | One, at possession | One per draw stage |
| Payments before completion | None | Interest on funds already drawn, depending on the lender |
The citable fact: Progress draw financing releases mortgage funds in stages tied to construction milestones, while a completion mortgage advances the full amount once, on possession day.
How long does a mortgage rate hold last on a pre-construction purchase?
A standard rate hold is set by each lender and is normally shorter than the time between signing a new build purchase agreement and taking possession. Buyers on longer builds typically need to renew or re-apply for a rate hold closer to the actual possession date rather than relying on the hold obtained at the start.
This is one of the most common surprises on a new build file. A buyer locks a rate at the start of a two-year build and assumes it carries all the way to possession, when in practice most holds do not stretch that far.
A standard rate hold usually runs 180 days. Some lenders go longer through their builder mortgage programmes, decided case by case rather than offered as a standard product. If your possession date sits beyond a normal hold, that is worth a conversation early, because it shapes which lender suits the build.
The citable fact: A rate hold obtained at the start of a new build purchase agreement typically does not last until possession, so most buyers need to revisit their rate closer to the actual closing date.
What happens if the builder’s possession date moves?
If possession is delayed past your rate hold, you will typically need a new rate, and your file may need to be re-underwritten if enough time has passed or your financial circumstances have changed. Your purchase agreement, not your mortgage, governs whether the builder owes you anything for the delay.
A construction delay is a builder and purchase agreement issue first, and a financing issue second. Once the delay is known, your broker’s job is to make sure your mortgage approval and rate can still get you to the new closing date.
The citable fact: A delayed possession date usually requires a new mortgage rate and, in some cases, a fresh underwriting review, separate from any recourse the buyer has against the builder.
Do I need a new pre-approval if possession is delayed?
Often, yes. A pre-approval reflects your income, debts and credit at the time it was issued, and lenders generally expect updated documentation if enough time has passed before the mortgage actually funds. The longer the delay, the more likely your file needs a fresh look.
This is not just paperwork. Your income, debts, and the mortgage stress test itself can all change between the day you signed a purchase agreement and the day a delayed home is finally ready.
The citable fact: A significant possession delay generally means updating your pre-approval documentation, since income, debt and stress test conditions can change over a long build.
How does the mortgage stress test apply to a new build purchase?
The mortgage stress test applies to a new build purchase the same way it applies to resale: you must qualify at the greater of your contract rate plus 2%, or a 5.25% floor. Because a new build can take a long time to close, your income and debt situation at the time of final funding, not just at the time you signed, is what matters most.
A buyer who qualified comfortably when they signed a purchase agreement two years earlier can find their situation has changed by possession. New debt, a change in income, or a change in credit can all affect final approval.
The citable fact: The mortgage stress test applies to new build purchases using the same greater-of-contract-rate-plus-2%-or-5.25%-floor rule used on resale purchases, and it is applied again based on your circumstances at the time of final funding.
What down payment rules apply to a new build in Alberta?
The federal minimum down payment rules apply the same way to a new build as to resale: 5% on the first $500,000 of the purchase price, 10% on the portion between $500,000 and $1,500,000, and 20% at or above $1,500,000. New construction purchasers are also eligible for a 30-year insured amortization, which lowers the required payment and raises qualifying room.
Because these rules are marginal, a purchase priced above $500,000 blends two brackets rather than applying one rate to the whole price. Below is how that works on an illustrative purchase price.
| Portion of purchase price | Minimum down payment |
|---|---|
| Up to $500,000 | 5% |
| $500,000 to $1,500,000 | 10% on the portion in this band |
| $1,500,000 and above | 20%, default insurance unavailable |

This example is illustrative only, built from the confirmed federal brackets, and is not a quote for any specific buyer’s file.
The citable fact: Alberta new build purchases follow the same federal down payment brackets as resale, 5% on the first $500,000, 10% on the portion up to $1,500,000, and 20% above that.
Does mortgage default insurance work differently on new construction?
The premium schedule is the same for new construction as for resale, based on loan-to-value. Using the $650,000 example above, a loan-to-value just under the ceiling falls in the 90.01% to 95% band, which carries a 4.00% premium on the total loan amount.
New construction buyers also gain access to the 30-year insured amortization option, which resale buyers without first-time buyer status do not automatically get. That option carries its own 0.20% premium surcharge.

This is an illustrative calculation only, using confirmed CMHC premium bands, and is not a quote. The premium is normally added to the mortgage rather than paid in cash.
The citable fact: Mortgage default insurance premiums apply to new construction on the same loan-to-value schedule as resale, with the 90.01% to 95% band carrying a 4.00% premium.
What documents does my lender need before final advance?
Before a completion mortgage funds, your lender typically wants updated income and employment documents, confirmation the home is enrolled with the required new home warranty coverage, the final statement of adjustments from your lawyer, and confirmation of your down payment source. Requirements vary by lender and by how long has passed since your initial approval.
Start gathering updated documents as soon as your possession date is confirmed. Waiting until the last few weeks before closing is the most common cause of a stressful, rushed final approval.
The citable fact: Final funding on a new build completion mortgage typically requires updated income documents, warranty enrolment confirmation, and a final statement of adjustments from a real estate lawyer.
What if my rate hold expires before the build is complete?
If your rate hold expires before the build is finished, you move to whatever rate is available closer to your actual completion date. Describing which option, a fixed or variable rate, or a shorter versus longer term, is the better bet in that situation is a decision for you and a broker to work through based on your specific file, not something this page can tell you.
This is one of the biggest reasons to stay in contact with your broker through a long build rather than only at the start and the end. Rate conditions can shift meaningfully over a one or two year build.
Check current live pricing any time at pekoe.ca/rates, updated daily, rather than relying on a rate you saw when you first signed.
The citable fact: A buyer whose rate hold expires before possession needs a new rate reflecting market conditions at that later date, and the right structure depends on the individual file.
How do I coordinate my broker, builder and lawyer on a new build closing?
Give your broker the builder’s estimated and firm possession dates as soon as you have them, keep your real estate lawyer looped in once a firm date is set, and update your broker immediately if your income or debt situation changes during the build. The further out your closing, the more this coordination matters.
A new build closing has more moving parts than resale, and the parts do not naturally talk to each other. Your broker, lawyer and builder each hold one piece of the timeline, and you are the one connecting them.
This is also where warranty enrolment matters to your financing. See how that connects on the Alberta new home warranty, explained.
The citable fact: Coordinating a new build closing means keeping your broker, lawyer and builder updated on the possession timeline and on any change to your financial situation as the build progresses.

Frequently asked questions
What is the difference between a completion mortgage and progress draws?
A completion mortgage advances the full loan amount once, on possession day, matching how a resale mortgage funds. Progress draws release funds in stages tied to construction milestones, and are typically used when a buyer is financing a custom build on land they already own.
Will my rate hold last until my new build closes?
Usually not on a longer build. Rate holds are set by the lender and are typically shorter than the time between signing a new build purchase agreement and taking possession, so most buyers need a new rate closer to closing.
What happens if my builder delays possession?
You will typically need a new mortgage rate, and your file may need updated documentation if enough time has passed or your finances have changed. Any compensation for the delay itself comes from your purchase agreement with the builder, not from your mortgage.
Do I need to requalify if my possession date moves significantly?
Often, yes. Lenders generally expect updated income, debt and credit information if a meaningful amount of time has passed since your original approval.
Does the mortgage stress test apply to new construction?
Yes, in the same way it applies to resale. You must qualify at the greater of your contract rate plus 2%, or a 5.25% floor, based on your circumstances at the time your mortgage actually funds.
How much down payment do I need for a new build in Alberta?
The same federal minimums apply as resale: 5% on the first $500,000 of the purchase price, 10% on the portion up to $1,500,000, and 20% at or above that. These are minimums, and a specific lender or programme may require more.
Is default insurance different for new construction?
The premium bands are the same as resale, based on your loan-to-value at the time of funding. New construction buyers also have access to a 30-year insured amortization option, which carries its own 0.20% premium surcharge.
What documents will my lender want before funding?
Expect requests for updated income and employment documents, confirmation the home carries the required new home warranty coverage, a final statement of adjustments from your lawyer, and confirmation of your down payment source. Exact requirements vary by lender.
What if rates have changed a lot since I signed my purchase agreement?
You will be offered current market pricing closer to your actual completion date rather than the rate available when you signed. Whether a fixed or variable rate, or a particular term, fits your situation best depends on your file and is worth discussing directly with a broker.
Why does warranty enrolment matter to my mortgage?
Lenders financing new construction want confirmation the home is enrolled with a licensed warranty provider because it protects the collateral behind the loan. This is a standard document requested before final funds are advanced.
Who should I keep updated during a long new build?
Your mortgage broker, your real estate lawyer, and your builder each hold different pieces of the closing timeline. Update your broker as soon as you know a possession date has changed or your financial situation has shifted.
