Construction mortgages in Nova Scotia: how draws actually work
The first result for this search is a credit union brochure; the next two are a developer’s blog. Nobody arranging construction financing has written down how the draws, the holdback and the conversion work in this province. This is that page.
How does a construction mortgage work in Nova Scotia?
The lender approves a total based on your land plus the build cost, then advances it in three or four draws as an appraiser confirms each stage — foundation, lock-up, drywall, completion. You pay interest only on what has been advanced, the last draw waits for the 10% builders’ lien holdback period, and the loan converts to a standard mortgage when the house is finished.
What a construction mortgage is, and how it differs from a purchase
A purchase mortgage funds once, on closing day, against a finished house that has been appraised. A construction mortgage funds in stages against a house that does not exist yet, so the lender is managing a different risk: that the money goes into the ground in the right order and that the finished home is worth what was projected. That is why the lender wants a fixed-price contract or a detailed budget, an appraisal of the as-completed value, a schedule, permits, proof of the builder’s warranty enrolment, and course-of-construction insurance before the first dollar moves — and why an appraiser visits before every draw.
The draw schedule, with a real Nova Scotia example
Schedules vary by lender, but a typical four-draw residential build on a $520,000 total project cost (lot plus build) releases funds roughly like this. The percentages are cumulative and illustrative; your lender sets the actual stages.
| Draw | What must be complete | Cumulative | Advanced to date |
|---|---|---|---|
| Land / start | Lot purchased or owned, permits issued, foundation poured | 15% | $78,000 |
| Lock-up | Framing, roof, windows and exterior doors in — the building is weather-tight | 40% | $208,000 |
| Mechanical and drywall | Rough plumbing, electrical and HVAC inspected; insulation and drywall complete | 65% | $338,000 |
| Completion | Occupancy permit, final inspection, well and septic sign-off, insurance converted | 100% | $520,000 |
Two consequences matter. First, your own money goes in first: the down payment (or the lot equity) is spent before the lender’s first advance, so the early stages are self-funded. Second, the builder is paid in arrears: each draw reimburses completed work, so the builder’s contract needs to match the lender’s stages or someone is carrying a gap.
The builders’ lien holdback — the detail nobody covers
Nova Scotia’s Builders’ Lien Act requires the owner to hold back 10% of the value of work and materials as security for subcontractors and suppliers who might not have been paid by the general contractor. The holdback is released only after the lien period following completion has expired with no liens registered. Lenders build this into the final draw: the last 10% is not released on the day you get the occupancy permit, it is released after the lien period. Builders know this; first-time owner-builders often do not, and it is the most common reason the last month of a build feels cash-starved. Your lawyer handles the lien search and the release.
Progress-advance versus completion mortgages
A progress-advance mortgage is the draw structure above and is what most self-directed builds use. A completion mortgage funds once, at the end, and is common when a builder finances the construction themselves and sells you a finished home — you sign a purchase agreement, put down a deposit, and your mortgage closes on completion like any purchase. If you are buying a new build from a builder in a subdivision, you probably need the second; if you own the lot and are hiring the builder, you need the first.
CMHC on a new build
Insured construction is available. CMHC Improvement funds a single advance where the improvements are under 10% of the as-improved value, and progress advances above that. First-time buyers can use CMHC Home Start for a 30-year amortization on a newly built home that has not been occupied. The minimum down payment is the same as a purchase — 5% of the first $500,000 and 10% of the remainder (1–2 units) — and the as-improved value must be below $1,500,000. Nova Scotia charges no provincial sales tax on the insurance premium.
Interest-only during the build, then the conversion
During construction you pay interest monthly on the amount advanced so far — small at the foundation stage, larger by drywall. When the final draw is released the loan converts to a standard mortgage: you choose a term and a rate at that point (some lenders let you hold a rate at the outset), and the amortization starts. You are qualified for the full amount at the outset at the stress-test rate — the greater of the contract rate plus 2% and 5.25% — so the conversion is not a second approval as long as nothing has changed.
What lenders need from your builder
- A signed fixed-price contract with a stage schedule, or for cost-plus builds a detailed budget with a contingency (lenders commonly want 10% or more).
- Enrolment in a new-home warranty program, where applicable — most lenders require it on a contracted build.
- Plans and specifications, the building permit, and where relevant the on-site sewage (septic) approval from Nova Scotia Environment.
- Proof of the builder’s liability insurance, and course-of-construction insurance on the project in the owner’s name.
Nova Scotia specifics that stall draws
- Well and septic sign-off. On an unserviced lot — most of rural Nova Scotia — the final draw waits for a potability test on the well and the septic installer’s certificate. Drilling the well early avoids finding out at the end that the lot needs a treatment system.
- Oil tanks and wood stoves. If the finished home is oil-heated or has a wood stove, the insurer will want the tank installation certificate and a WETT inspection before writing the permanent policy, and the lender needs that policy to convert the loan.
- Rural appraisers. Progress inspections in Guysborough, Digby or Victoria counties can take longer to schedule than in HRM. Build a week into each draw request.
- Runs past the interest-only window. Most lenders allow 12 months; extensions are granted with a progress report and an updated cost-to-complete. The thing they will not do is fund a project that has run out of money to finish, so the contingency is not optional.
Common reasons a draw is refused
- The stage is not actually complete — the appraiser measures against the lender’s definition, not the builder’s.
- The cost to complete exceeds the money left in the loan, usually because of change orders.
- A lien has been registered against the property.
- A permit or inspection is outstanding.
- Insurance has lapsed, or the policy does not cover the current stage.
Building more than a house
A duplex, a home with a secondary suite, or an owner-occupied triplex or fourplex can be financed as residential construction. Five or more units, a rental building, or a development for sale is commercial construction financing — appraised on income, drawn against a quantity surveyor’s reports, and underwritten differently. That work is done through Indi Mortgage Commercial Division, where Riley also advises; if you are not sure which side of the line your project sits on, ask and the answer takes a minute.
Questions people ask
How does a construction mortgage work in Nova Scotia?
The lender approves a total amount based on the land value plus the build cost, then advances it in stages — typically three or four draws — as an appraiser confirms each stage is complete. You pay interest only on what has been advanced during the build, and the mortgage converts to a standard term when the house is finished.
What is the builder’s lien holdback and why does it delay my last draw?
Under the Nova Scotia Builders’ Lien Act the owner must hold back 10% of the value of work done as security for subcontractors and suppliers until the lien period after completion has expired. Lenders respect the holdback, so the final portion of the money is released after that period, not on the day the house is finished. Budget for it.
Can I use my land as the down payment?
Yes. If you own the lot outright, its appraised value counts as equity in the project; on a $520,000 total cost with a $100,000 lot owned clear, the lot is a 19% contribution before any cash. If the lot has a mortgage, the equity above that balance counts.
Do I need a licensed builder, or can I build it myself?
Both are financed, but differently. A contract with a builder enrolled in a new-home warranty program is the easiest file. Self-builds are financed by fewer lenders, usually need a larger down payment, a detailed budget, and evidence you can manage the trades; sweat equity is not counted as cash.
What if the build runs over the interest-only period?
Most lenders allow 12 months of construction, some 18. If the build runs long you apply for an extension, which lenders usually grant with a progress report and an updated cost to complete. Running out of money to finish is the bigger risk, which is why lenders require a contingency in the budget and check the cost-to-complete at every draw.
Do construction mortgages cost more?
During the build, yes — interest-only on advanced funds at a construction rate, plus an appraiser’s progress inspection at each draw. Once complete, the mortgage converts to a standard residential term at standard rates. Broker services are paid by the lender on standard construction files, the same as any other residential mortgage.
Can I get CMHC insurance on a new build?
Yes. CMHC Improvement covers construction: a single advance if the improvements are under 10% of the as-improved value, and progress advances above that. First-time buyers building a home can use CMHC Home Start for a 30-year amortization. Insured construction requires the same minimum down payment as a purchase — 5% of the first $500,000 and 10% of the rest, up to a price below $1,500,000.
