The client
A couple self-building in Moncton, New Brunswick, on land they purchased for the project. Four staged draws funded the build against a fixed budget, and the home passed its final inspection on schedule. The construction mortgage's last draw still didn't land in their account for weeks.

The problem
The couple assumed the final draw would release the moment the inspector signed off on substantial completion — the same as every earlier draw in the schedule. New Brunswick's construction-lien law works differently at the last stage.
Why the last $31,200 didn't move on schedule
- ▸Substantial completion passed inspection with no deficiencies noted
- ▸The lender's lawyer still held back 10% of the construction budget — $31,200 — from the final draw
- ▸The holdback exists to protect against subcontractor liens filed after the fact, and it isn't released until the statutory lien-filing period lapses with nothing registered
Nothing about the build itself was in question. The holdback is a feature of how construction-lien law protects unpaid subcontractors, not a sign that anything had gone wrong — but it meant a multi-week gap between "the house is done" and "the mortgage says so."
The numbers
The math on this file was straightforward once completion happened. The timing of the very last piece of it was the entire story.
| The completed self-build | Amount |
|---|---|
| Land purchase | $68,000 |
| Construction hard costs | $312,000 |
| Total project cost | $380,000 |
| Equity contribution (15%) | −$57,000 |
| Base mortgage at 85% LTV | $323,000 |
| CMHC premium (2.80% band) | +$9,044 |
| Total insured mortgage | $332,044 |
Holdbacks like this one are standard practice under construction-lien statutes across Canada, sized and timed by the specific statute and the lawyer's own risk assessment — not a fixed national rule, and not evidence of a problem with the build itself.
The ratio math, at the qualifying rate
| Ratio check | Figure |
|---|---|
| Minimum qualifying rate on a 4.95% contract rate | 6.95% |
| Qualifying payment, 25 years | $2,315/mo |
| GDS (payment + $280 tax + $130 heat) ÷ $8,100 income | 33.6% |
| TDS (GDS numerator + $300 car loan) ÷ $8,100 income | 37.3% |
New Brunswick's flat 1% transfer tax on the $68,000 land purchase came to $680, paid at the land closing rather than at project completion.
The solution
An FCNB-licensed New Brunswick mortgage broker built the holdback into the couple's cash-flow plan from the start of the project, not as a surprise at the end.
First, flagged the lien holdback at the very first draw meeting. Knowing in month one that 10% of the budget would sit back for weeks after completion meant the couple never expected to see it land the day the inspector signed off.
Second, arranged a short-term bridge sized exactly to the $31,200 holdback to cover move-in costs and final trades' invoices during the lien-filing window, rather than delaying occupancy.
Third, confirmed with the lender's lawyer the exact date the lien period lapsed, so the bridge could be repaid the moment the final draw actually released, not carried longer than necessary.
The outcome & the closing math
The build funded at $332,044 insured, with GDS at 33.6% and TDS at 37.3%. The $31,200 holdback released to the couple the day the lawyer confirmed no lien had been filed, and the bridge was repaid the same week.
No deficiency, no dispute with a trade — the entire delay was the statutory lien-filing period running its course, exactly as construction-lien law intends.
What to take from this file
- 01A holdback at completion is not a red flag. It's how lien law protects subcontractors, and it applies whether the build went perfectly or not.
- 02Flag the holdback before the build starts, not at the final draw meeting. A client who knows to expect a gap doesn't panic when the money doesn't move on inspection day.
- 03A short bridge, sized to the exact holdback, is cheaper than an unplanned scramble. Knowing the dollar figure in advance made the bridge a formality, not an emergency.
- 04Confirm the lien-period expiry date directly with the lender's lawyer. That date, not the completion date, is what actually triggers the final release.
