The client
A homeowner in Courtenay, a market whose renovation activity runs alongside, not instead of, Canada's housing starts, planning a kitchen and bathroom renovation — new cabinetry, fixtures, flooring, no structural changes, no permit for a new structure. The first call to their broker asked specifically about “a construction mortgage,” because that was the only mortgage product name they had heard associated with renovation work, and they were bracing for inspections and a multi-stage funding process.

The problem
The word “renovation” covers two very different underwriting problems, and the homeowner had assumed the wrong one applied. A construction (draw) mortgage exists to manage the risk of work that has not happened yet — staged inspections confirm progress before each advance releases. A cosmetic renovation with a fixed contractor quote and no structural changes carries none of that risk: the scope is defined, the price is fixed, and there is nothing mid-build for an inspector to verify stage by stage.
Treated as a construction file anyway, this renovation would have meant unnecessary inspection fees, a slower closing, and interest calculated on funds released in pieces the contractor did not actually need staged.
The numbers
A single equity take-out refinance paid off the existing mortgage and advanced the full renovation amount in one payment to the contractor at closing.
| The renovation refinance | Amount |
|---|---|
| Existing mortgage balance | $310,000 |
| Renovation budget | $65,000 |
| New mortgage | $375,000 |
At $375,000 against a $560,000 value, this refinance sits at 67.0% loan-to-value — well under the 80% ceiling that keeps it uninsured. Being uninsured, this refinance carries no first-time-buyer or new-build condition, so a 30-year amortization was available outright, unlike the eligibility rule that applies to an insured purchase.
| Rate & payments (30-year amortization) | Figure |
|---|---|
| Contract rate — 5-year fixed (illustrative, not a quote) | 4.99% |
| Minimum qualifying rate — contract + 2% | 6.99% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,467 |
| Monthly P&I at the contract rate — what is actually paid | $1,999 |
| Amortization comparison, at the qualifying rate | Monthly P&I |
|---|---|
| 30-year amortization | $2,467 |
| 25-year amortization | $2,624 |
| Difference | $157 |
| TDS on the refinance | Monthly |

| P&I at the qualifying rate (30-year) | $2,467 |
| Property tax | $295 |
| Heat (lender-standard estimate) | $150 |
| Personal loan payment | $350 |
| Total $3,262 ÷ income $12,000 → TDS 27.2% | ✓ |
The solution
A BCFSA-licensed submortgage broker corrected the product assumption before it cost the client anything.
First, confirmed the scope was cosmetic, not structural. New cabinetry, fixtures and flooring, with a fixed contractor quote in hand, is a defined renovation — not the open-ended, unfinished work a construction-draw mortgage is built to manage.
Second, structured a single equity take-out refinance that paid the contractor in one advance at closing, with no inspections, no holdback schedule, and no construction-mortgage interest mechanics.
Third, took the amortization decision on its own merits once the file was confirmed uninsured — a 30-year amortization was simply available, the choice covered generally in 25 years or 30: the longer amortization isn't open to everyone.
The outcome & the closing math
One closing, one advance to the contractor, and no staged inspections at any point — the renovation proceeded on the contractor's own timeline once the funds were in hand.
As a refinance of an already-owned property, no land transfer tax applied here at any point.
What to take from this file
- 01The word “renovation” does not automatically mean a construction-draw mortgage. Whether draws are needed depends on whether the work is structural and unfinished, not on the word used to describe it.
- 02A fixed contractor quote is what makes a single advance possible. An open-ended, unquoted renovation is a different underwriting problem entirely.
- 03Being uninsured opens amortization choices an insured purchase does not have. The 30-year insured-amortization eligibility condition simply does not apply to this file.
- 04A longer amortization is a real trade-off, not a free lunch. $157 a month lower here comes with a longer payoff timeline — walk the client through both sides.
- 05Confirm what the client actually needs before naming a product. This call started with the wrong product name; the underwriting need was much simpler than the client expected.
