Construction Mortgage BC: How Progress Draw Financing Works
Financing a construction project works fundamentally differently than financing a completed home purchase. Instead of receiving the full mortgage amount at once, funds are released in stages as the build progresses. Understanding this process before you start building can save significant cash flow stress and prevent surprises partway through your project.
I have spent 25 years focused specifically on private lending, construction, and commercial financing. Here is exactly how construction mortgages and progress draws work in BC.
Why Construction Financing Is Structured Differently
A completed home has a known, appraisable value. A construction project does not exist yet in its final form, which means the lender's risk profile changes throughout the build. Releasing the full mortgage amount upfront would expose the lender to significant risk if the project stalled or the build did not proceed as planned.
Progress draw financing solves this by tying fund releases to verified construction milestones. The lender only releases capital as work is actually completed and inspected, which protects both the lender and, in most cases, the borrower from overextending before the project is far enough along.
Typical Draw Schedules
While specific draw structures vary by lender and project size, a common schedule for a residential construction mortgage in BC includes draws at: foundation completion, framing and roof completion (lock-up stage), drywall and interior systems completion, and final completion ready for occupancy.
Each draw typically requires a site inspection confirming the stated stage has genuinely been completed before funds are released. Some lenders use third-party inspection services; others rely on their own appraisers or inspectors. I coordinate this process with clients so there are no surprises about timing or requirements at each stage.
How Interest Is Calculated During Construction
One of the most important features of construction financing is that interest is typically calculated only on the funds actually drawn, not on the full approved mortgage amount. This keeps carrying costs significantly lower during the early stages of a build when only a portion of the total financing has been released.
As each draw is taken, the interest calculation adjusts to reflect the increasing balance. By the time the project reaches completion and the full amount has been drawn, the mortgage typically converts to a standard amortizing mortgage or is paid out through a separate permanent financing arrangement.
Land and Construction Combined Financing
Many clients need financing for both the land purchase and the subsequent construction. Structuring these together as a combined land and construction facility avoids the complexity of managing two completely separate financing approvals and allows the overall project to be assessed as a whole rather than piecemeal.
This is particularly relevant on Vancouver Island where raw land purchases for custom builds are common and where coordinating land acquisition with construction timing requires careful planning.
The Builder and Contractor Question
Lenders want to understand who is building the project and their track record. Owner-builders — those managing their own construction without a licensed general contractor — face additional scrutiny and a narrower lender pool, since the risk profile is different from a project managed by an experienced licensed builder.
If you are planning to owner-build, it is worth having this conversation with your broker before you finalize your plans, since it affects which lenders will consider the project and what additional conditions may apply.
Spec Builds and Development Projects
For builders constructing speculative homes for resale, or for larger multi-unit development projects, the financing requirements become considerably more complex. Lenders assess the project's marketability, the builder's track record with similar projects, and the broader market conditions for the finished product.
Institutional lenders are often less comfortable with spec and development financing than they are with owner-occupied construction. This is frequently where private capital and specialized institutional lenders become the right solution, providing the flexibility that a conservative bank underwriting model cannot accommodate.
Planning Your Construction Financing
The biggest mistake I see is people finalizing their building plans and budget before confirming their financing structure. The right time to talk to a broker who understands construction financing is before you have committed to a builder, a land purchase, or a specific build timeline — not after.
I work with builders, owner-builders, and developers across Vancouver Island and BC. If you are planning a construction project, book a free call early in the process and I will walk you through exactly what financing structure makes sense for your specific build.
