Financing a custom build, without the mystery.

How construction mortgages actually work in BC: qualifying, draw schedules tied to build milestones, the 10% builders lien holdback, and how fixed-price contracts make lenders comfortable.

Costs & BudgetingFebruary 20267 min read

A construction mortgage is not a normal mortgage — the bank pays for the house as it's built, in stages, against inspections. Once you understand the draw machine, the whole process stops being intimidating.

How the money actually flows

You qualify for the full amount up front, but funds are advanced in draws tied to completed milestones. After each stage, the lender's inspector or appraiser confirms progress and releases the next tranche:

The three things lenders actually check

A real budget from a real builder

Lenders lend against a detailed, line-item construction contract — a fixed-price design-build contract is the cleanest package you can hand them.

Qualified borrower at completion

You're underwritten on the finished home's value and your ability to carry the final mortgage, not just the land.

BC lenders require a Licensed Residential Builder and third-party home warranty enrolment before first draw.

The holdback everyone forgets

BC's Builders Lien Act requires 10% of each payment to be held back for 55 days after substantial completion. It protects you from trade liens — but it means your cash-flow plan must carry that 10% gap. We structure our draw schedules around it so nobody discovers the holdback at the worst moment.

Interest-only during construction: you pay interest only on funds drawn to date — early months are cheap, the final months carry the full balance. Budget the carry cost like any other line item; we include it in feasibility.
