How a Construction Mortgage Works in BC
Building your own home is one of the most rewarding things you can do—and financing it works very differently from buying an existing house. If you're planning a build anywhere in BC, understanding how a construction mortgage is structured will save you a lot of stress before you break ground.
I'm Joel Olson, and I help clients finance new builds across BC, including plenty of rural and acreage builds. Here's the plain-English version.
The Big Difference: Money Comes in Stages
With a regular mortgage, the full amount is paid to the seller at closing. A construction mortgage works on a draw system instead: the lender releases money in stages as your build hits certain milestones. You're not handed a lump sum—you receive funds as the work gets done and gets inspected.
How the Draws Typically Flow
Most construction mortgages release funds across several draws tied to completion stages. A typical structure looks something like this:
- Draw 1 — Foundation stage: released once the foundation is complete.
- Draw 2 — Lock-up stage: when the home is framed, roofed, and can be locked (windows and doors in).
- Draw 3 — Drywall/finishing stage: as interior work progresses.
- Final draw — Completion: once the home is finished and often after an occupancy permit is issued.
Before each draw is released, the lender usually sends an appraiser or inspector to confirm the work is actually done. This protects both you and the lender—you only borrow against real, completed value.
What This Means for Your Cash Flow
Because money arrives in stages, you (or your builder) often need to fund each stage first and get reimbursed at the draw. That's a critical planning point: you need enough working capital, or a builder whose contract accounts for draw timing, to keep the project moving between draws. Interest during construction is typically charged only on the funds drawn so far, not the full mortgage amount.
What Lenders Want to See Before They Approve
- Detailed plans and a fixed-price building contract from a licensed builder.
- A realistic budget with a contingency for overruns—lenders like to see you've planned for surprises.
- Your qualifying income and credit, just like any mortgage.
- The land—whether you already own the lot or are buying it as part of the project.
Building Rural? There's an Extra Layer
A large share of new builds in the BC Interior and North are on acreage or rural land. That combines two specialties—construction financing and rural lending—and not every lender is comfortable with both. Well and septic, zoning, and the 10-acre lending value cap all come into play. This overlap is exactly where I spend a lot of my time; see my rural and acreage financing page for more on that side.
Plan the Financing Before You Plan the Build
The smoothest builds are the ones where the financing is locked in and understood before the first shovel goes in the ground. If you're thinking about building in BC, reach out early and I'll walk you through the construction mortgage structure, what you'll qualify for, and how to line up your draws so the project never stalls waiting on money.
