First, which kind of new build is this?
The word "construction" covers two quite different files, and they are financed in completely different ways.
- Buying a finished or nearly finished home from a builder — including a pre-sale condo. Financing here looks much like any purchase: the mortgage funds once, at completion. The complications are timing and rate holds over a long closing, not draws.
- Building it, or having it built for you, on land you own or are buying — a custom home, an acreage build, a knock-down and rebuild. This needs a progress-draw mortgage, and it is the one with real mechanics to understand.
If you are not sure which side of that line your project sits on, that is the first thing to sort out, because it changes what you need to have ready.
How a progress-draw mortgage works
Instead of one advance, the lender releases the money in instalments as the build reaches defined stages, with an inspection confirming each stage before the funds go out. Sagen's Progress Advance program is a good, concrete illustration of the shape of it: under full service the first draw comes when the property is 15% complete — excavation, backfill and foundation — and includes 100% of the land cost less your down payment. Sagen pays for up to four progress advance inspections; if the build needs more than four advances, the additional inspections are at your cost (Sagen).
Two eligibility points matter a lot in practice. Financing runs to 95% LTV on one to two units and 90% on three or four, with at least one unit owner-occupied, and with the property under $1,500,000 in value above 80% financing. And condominiums are not eligible under this program — a pre-sale condo is a purchase, not a construction file. The build has to comply with the National Building Code and the applicable provincial and municipal codes.
The practical consequence of the draw structure is cash flow. You carry the cost of each stage until the inspection clears it, which is why builds go sideways on timing far more often than on approval. Sequencing the draws against your builder's payment schedule before you start is the single most useful thing to do on one of these files.
The builders lien holdback
This one is law, not lender preference, and it surprises people. Under BC's Builders Lien Act, a holdback equal to 10% of the greater of the value of the work or material actually provided, and the amount of any payment made on account of the contract price, must be retained. The holdback period expires 55 days after the certificate of completion is issued — or, where there is no certificate of completion, 55 days after the head contract is completed, abandoned or terminated (Builders Lien Act, ss. 4 and 8).
So plan on 10% of each stage sitting unavailable, and on a gap of nearly two months at the end before the last of it releases. Budgeting as though the full draw arrives is how people end up short at the worst possible moment.
A longer amortization is available on a new build
Insured amortizations normally cap at 25 years, but 30 years is available on new construction — and for new builds it is not limited to first-time buyers. That is a meaningful difference in the monthly payment on a build, and it is worth asking about specifically rather than assuming the 25-year default.
Two tax reliefs worth real money on a build
The first-time home buyers' GST/HST rebate. This is new, it is now in force, and a lot of people building their first home do not know it exists. It recovers up to 100% of the GST paid, to a maximum of $50,000. The full rebate applies to homes up to $1,000,000, then reduces gradually between $1,000,000 and $1,500,000, with nothing available above $1,500,000 (CRA).
Critically, it covers homes you build yourself, not only purchases from a builder. The conditions are that you are 18 or older, a Canadian citizen or permanent resident, have not lived in a home you or your spouse owned as your primary residence in the current or previous four calendar years, and have not claimed this rebate before. For a self-build, construction must begin on or after 20 March 2025 and before 2031, be substantially complete before 2036, and be first occupied before 2036 (CRA). Those start dates are worth checking against your own timeline early, because they are not negotiable afterwards.
The BC newly built home exemption from property transfer tax. A home that has not been occupied since construction qualifies for a full exemption at a fair market value of $1,100,000 or less, with a partial exemption declining between $1,100,000 and $1,150,000. You need to move in within 92 days of registration at the Land Title Office and keep it as your principal residence through the first year of ownership; leaving early means repaying a portion (Province of BC).
These two stack, and neither is automatic — both have to be claimed correctly. If you are a first-time buyer building in the Okanagan, it is worth being deliberate about the sequence.
What to have ready before you apply
A fixed-price build contract, or a detailed cost breakdown if it is cost-plus. Plans and specifications. The builder's details and credentials. Proof of your land position, whether owned or under contract. A realistic construction schedule. And the permits, or a clear account of where they stand.
Lenders differ a great deal on construction files — on how many draws they will fund, on how they treat cost-plus contracts, on acreage and rural servicing, and on whether they will lend at all where you are acting as your own general contractor. That last one narrows the field considerably. With 50+ lenders available there is usually a good fit, but it needs to be found deliberately rather than discovered late.
Bring me the plans and the builder's quote and I will tell you which lenders suit the project and what the draw schedule should look like. There is no cost to you on conventional mortgages, and no credit check needed to talk it through.
Building in the Central Okanagan
Two local realities shape almost every build file I see here, and both are about thresholds rather than construction.
The insured cap, and where Okanagan builds land relative to it
In July 2026 the Central Okanagan single-family benchmark sat at $1,072,400, up 2.3% year over year, with townhomes at $709,500 and condominiums at $490,700 (Association of Interior REALTORS). A custom build on a view lot in the Upper Mission, Wilden or Lakeview Heights routinely finishes well above that, and once the finished value passes $1,500,000 insured financing is off the table entirely — you are into conventional lending at 20% down or more, with a different and shorter list of lenders. Knowing which side of that line your project lands on changes the whole financing structure, so it is the first number I want.
Two tax thresholds that bite at exactly these values
The first-time buyers' GST rebate is full up to $1,000,000 of value and tapers to nothing at $1,500,000. The newly built home exemption from property transfer tax is full at $1,100,000 or less and tapers away by $1,150,000 (Province of BC). Set those against a Central Okanagan single-family benchmark of $1,072,400 and you can see how tight it is: a new build near the local benchmark sits just inside the property transfer tax exemption, and a modest overrun on finishings can push it out. That is a real amount of money turning on a decision made at the drawings stage.
Beyond the thresholds, the recurring local complications are sloped lots, which raise servicing and foundation costs and can affect the appraisal, and acreage toward East Kelowna, Lake Country and Glenmore where wells, septic and land value narrow the lender list. Bring me the plans and the builder's quote early and I'll tell you which lenders suit the project.
