Private Construction Mortgages in BC: How They Work and Who Qualifies

Mei owned a 1970s bungalow in Richmond with excellent lot value but an outdated layout. Her plan: add a legal secondary suite, renovate the main floor, and modernize the entire property. The bank's response was predictable — they needed finalized permits, a fixed-price contract with a licensed builder, and a six-week underwriting timeline. Mei had a reliable contractor ready to start in two weeks and permits still in review with the city. A private lender funded her project with a draw mortgage, releasing funds as construction milestones were completed.

Private construction mortgages solve a specific problem that traditional lenders struggle with: funding projects where the value doesn't exist yet. In BC's renovation-heavy market, these loans fill a critical gap for homeowners and developers who need flexible capital tied to building progress rather than current property condition.

What Is a Private Construction Mortgage?

A private construction mortgage is a short-term loan secured against property that funds building or renovation work. The answer is: unlike standard mortgages that advance the full amount at closing, construction mortgages release funds in stages called "draws" as work progresses.

The key structural differences from conventional mortgages:

• Draw-based funding: Money releases in 3-5 installments tied to construction milestones, not as a single lump sum
• Interest-only payments: You pay interest only on the amount drawn, not the total approved loan
• As-complete valuation: Lenders underwrite based on what the property will be worth after construction, not its current condition
• Short terms: Typically 6-18 months, designed to bridge the construction period until you refinance with a conventional lender

This structure protects both borrower and lender. The borrower doesn't pay interest on money sitting unused. The lender confirms work is progressing before releasing additional funds.

How Draws Work in BC Private Construction Loans

In BC, draw mortgage structures typically follow a 3-5 draw schedule tied to inspection milestones. The lender or their representative inspects the property before each draw to verify completed work matches the construction plan.

A typical four-draw schedule for a major renovation might look like:

Most BC private lenders charge a draw inspection fee of $150-300 per inspection. Some lenders hold back 10-15% of the final draw until a completion certificate or final inspection sign-off from the municipality.

For Mei's Richmond project, her lender structured a four-draw schedule with the first draw covering demolition and suite prep work, allowing her contractor to start immediately while permits for the upper-floor work were still being processed.

Who Uses Private Construction Mortgages in BC?

Private construction financing serves several distinct borrower profiles in BC's market:

Major Renovations

Homeowners undertaking significant renovations — kitchen/bath overhauls, additions, basement developments — who need capital before the improved value exists. Banks typically won't lend against projected value.

Secondary Suite Additions

With BC's housing legislation encouraging laneway homes and secondary suites, many homeowners are adding rental units. These projects often cost $150,000-400,000 and generate immediate rental income once complete, making them ideal candidates for short-term construction financing that refinances into a conventional mortgage.

New Builds on Owned Land

Owners who purchased vacant land or demolished an existing structure and need construction financing. Private lenders can move faster than institutional construction loan programs and have more flexibility on builder requirements.

Teardown-Rebuilds

In Metro Vancouver markets like Vancouver West, Burnaby, and North Vancouver, teardown-rebuilds are common. The existing home has minimal value, but the lot supports a $2-4M new build. Private construction mortgages fund the build period before permanent financing.

What Private Lenders Evaluate for Construction Loans

Private construction lenders in BC focus on different criteria than standard mortgage underwriters:

As-Complete Value

The projected value after construction is the primary metric. Lenders typically advance up to 65-75% of the as-complete appraised value. This appraisal requires detailed construction plans, permits, and sometimes a cost breakdown.

Builder Experience

Lenders want confidence the project will actually finish. They evaluate the contractor's track record, licensing status, and sometimes require a fixed-price contract. For owner-builders, expect more scrutiny and potentially lower advance rates.

Permit Status

While some private lenders will fund before permits are fully approved, most require at least a permit application in process. Lending against unpermitted work creates title and insurance complications that add risk.

Exit Strategy

How will this loan be repaid? Lenders want to see a clear path to either refinancing with a conventional lender post-construction or selling the completed property. Strong exit strategies get better terms.

Borrower Equity

Even with as-complete valuation, lenders want borrowers to have meaningful equity at risk. Expect to demonstrate 25-35% equity in the completed project value.

Typical Terms for BC Private Construction Mortgages

In BC, private construction mortgage terms typically fall within these ranges as of May 2026:

• Interest rates: 8.99-12.99% for most construction loans, with rates varying based on project complexity and borrower profile
• Loan term: 6-18 months, with 12 months being most common for major renovations
• Lender fee: 1-3% of the loan amount, charged upfront
• Maximum LTV: 65-75% of as-complete value
• Interest calculation: Interest-only on drawn amounts, calculated monthly
• Draw inspection fees: $150-300 per inspection

A $400,000 construction loan at 10.99% with a 2% lender fee would cost approximately $8,000 in fees upfront, plus roughly $3,660 in monthly interest once fully drawn.

Construction Mortgage Risks and How to Mitigate Them

Private construction loans carry specific risks that borrowers should plan for:

Cost Overruns

Construction projects routinely exceed initial budgets by 10-20%. Mitigation: Build a 15-20% contingency into your budget and loan request. Lenders respect borrowers who plan for reality.

Permit Delays

BC municipalities vary widely in permit processing times. Vancouver can take 6+ months for complex permits. Mitigation: Factor permit timelines into your construction schedule and loan term. Consider a longer initial term rather than paying for extensions.

Incomplete Builds

If construction stalls, you're paying interest on a half-finished property that can't be refinanced or sold. Mitigation: Vet your contractor thoroughly, use a draw schedule that keeps them motivated, and maintain reserves to handle disruptions.

Interest Rate Risk

If your exit strategy is refinancing and rates rise significantly, your debt service ratios may not qualify for conventional financing. Mitigation: Stress-test your refinance at rates 1-2% higher than current.
