Construction Financing · BC & Alberta · Institutional, alternative and private
A build is financed in stages. So is the mortgage.
Construction lending works nothing like a purchase. Money advances against progress rather than at closing, the appraisal is of something that does not exist yet, and cash flow between draws is the thing that sinks projects. This is how the structure actually works.

The mechanics
How a progress-draw mortgage actually advances.
The single most useful thing to understand before you start: you fund the work, then the lender reimburses against verified progress. Not the other way around.
Stage 01
Land and equity position
Owned land with clear title is normally the strongest starting position, and equity already in the lot can count toward the borrower contribution. Land bought subject to financing, or held with existing debt against it, changes the structure and the lender list.
Stage 02
Budget, plans and permits
A lender is underwriting a project, not just a borrower. Stamped plans, a line-item budget, the building permit and a realistic schedule are what turn an idea into something financeable. Incomplete packages are the most common reason a construction file stalls.
Stage 03
Appraisal on an as-complete basis
The appraiser values what the finished building will be worth given the plans and budget. That as-complete figure, not today’s land value, is what most of the structure is built on.
Stage 04
The draw schedule
Advances are released at defined milestones, commonly tied to stages such as foundation, framing and lock-up, completion. Each draw is triggered by an inspection confirming the work is actually in place. Lenders differ on the number of draws and what each requires.
Stage 05
Holdbacks and lien legislation
Provincial construction lien legislation requires a portion of each advance to be held back for a statutory period, and lenders apply their own holdbacks on top. This is the part borrowers underestimate most, because it means you never receive the full value of the work at the moment you complete it.
Stage 06
Completion and take-out
On completion the construction facility is repaid, usually by converting to or refinancing into a conventional mortgage. That take-out should be planned at the start rather than arranged in a hurry at the end.
Requirements vary by lender, property, project, borrower and financing structure. Nothing here is a commitment to lend or a statement of any lender's current criteria.

The thing that goes wrong
Projects fail on cash flow between draws, not on the total.
Almost every construction file that gets into trouble does so for the same reason. The overall numbers worked. What did not work was the gap between paying trades for completed work and receiving the advance that reimburses it, compounded by holdbacks that keep part of each draw out of reach until the statutory period expires.
So the question that matters is not whether the project pencils out. It is whether you can carry each stage from your own resources until the lender catches up, and what happens if a draw inspection comes back short or a trade misses a date.
Cost overruns are the other half. Budgets set before ground breaks meet a real world of material prices, trade availability and municipal timelines. Lenders expect a contingency for that reason, and the borrowers who finish comfortably are the ones who treated it as real money rather than a formality on a spreadsheet.
- Your ability to carry each stage before the draw is advanced
- Statutory lien holdbacks, plus any lender holdback on top
- A contingency that reflects your actual project, not a token line item
- Interest carried during construction, which is a live cost from the first advance
- The builder or general contractor: track record, insurance, warranty enrolment where required
- Municipal timelines for permits and inspections, which you do not control
Requirements vary by lender, property, project, borrower and financing structure. Nothing here is a commitment to lend or a statement of any lender's current criteria.
Not all builds are the same file
Residential construction and commercial construction diverge early.
People use “construction financing” for both, but they are different products with different lenders, different underwriting and different documentation. Knowing which one your project is saves a great deal of wasted time.
Residential construction
A custom home you intend to live in, or a single-family rebuild
Underwritten mainly on you: income, credit, equity in the land
As-complete appraisal against comparable finished homes
New home warranty enrolment where provincial rules require it
Take-out is normally a conventional residential mortgage on completion
Commercial and development construction
Multi-unit, mixed-use, industrial, or land servicing into buildable lots
Underwritten mainly on the project: budget, pro forma, exit and sponsor experience
Pre-sales, pre-leasing or absorption assumptions often form part of the case
Environmental, geotechnical and municipal approvals carry real weight
Take-out is a sale, a lease-up and refinance, or a move to institutional debt
Commercial construction is covered further on the commercial mortgages page. Requirements vary by lender, property, project, borrower and financing structure. Nothing here is a commitment to lend or a statement of any lender's current criteria.

Construction questions
What builders and owner-builders ask.
General information for British Columbia and Alberta. Requirements vary by lender, project and structure; nothing here states any lender’s current criteria.
How much of my own money do I need in the project?
Lenders express this as a required borrower contribution and they set it differently depending on the project, the as-complete value, your experience and whether the land is already owned free and clear. Equity in land you already hold frequently counts toward it. Rather than quote a percentage that may not apply to your file, send the budget and the land position and I will tell you where it realistically sits.
Do I get the money up front?
No, and this surprises people. Construction financing advances in stages against verified progress, so you fund the work first and the lender reimburses after an inspection confirms it is in place. Planning for that gap is the most important part of the exercise.
What is a holdback and why does it matter?
Provincial construction lien legislation requires a portion of each payment to be held back for a statutory period so unpaid trades and suppliers have recourse. Lenders may apply further holdbacks of their own. It matters because it means you do not receive the full value of completed work at the moment you complete it, and that has to be funded from somewhere.
Can I be my own general contractor?
Some lenders permit an owner-builder and many do not, and those that do usually apply additional conditions and may require relevant experience. Provincial new home warranty rules also apply and can restrict it further. If this is your plan, raise it in the first conversation, because it materially narrows the lender list.
What documents do I need to start?
A realistic line-item budget, the plans, the land details including title and any existing debt, your own financial position, and the builder’s information including their track record and insurance. If the permit is issued, that too. The completeness of this package is the single biggest factor in how quickly a construction file moves.
What happens if the build goes over budget?
It depends how far over and whether you have contingency left. Lenders generally will not simply increase the facility mid-build, so an overrun usually has to come from your own resources or from a secondary facility, which is expensive and arranged under pressure. This is exactly why the contingency is not a formality.
Do you finance land purchase and servicing as well?
Yes, though raw land and servicing sit at a different point on the risk curve than vertical construction and are financed accordingly, often with alternative or private capital before a project is shovel-ready. The exit matters more than anything else on these files.
What happens to the mortgage when the build is finished?
The construction facility is repaid, normally by converting to or refinancing into a conventional mortgage on the completed property. Some lenders offer a single facility that converts automatically. Either way, the take-out should be planned at the start, because arranging it at the end under time pressure is where costs appear.
