Construction & Development Financing

Construction financing is not simply a mortgage with several advances. The lender is funding a changing asset whose value, legal status, cost to complete and marketability can change every month. The central question is therefore not only “What is the property worth?” but “Is there enough verified capital, time and execution capacity to reach the finished state on which repayment depends?”

A strong construction plan connects five states: the property today, the approved scope, the money required to complete it, the draw process that releases capital, and the permanent repayment or sale outcome. If any one of those five states is vague, a project with apparently strong equity can still fail.

A homeowner building a custom residence, a buyer using an insured improvement program, a developer constructing rental apartments, a business expanding an industrial facility and a purchaser closing a pre-construction condominium do not present the same credit risk. The financing structure depends on who controls construction, who owns the land, whether the property already produces income, and what event creates the permanent exit.

Pre-construction closing financing is especially different: the purchaser is generally not funding the builder’s construction draws. The borrower is financing the contractual purchase at occupancy or final closing, often years after signing the original agreement.

Loan-to-cost (LTC) compares financing with recognized project cost. Loan-to-value (LTV) compares secured debt with accepted property value, which may be measured as-is, as-complete or stabilized depending on the stage and lender. Cost-to-complete asks whether the undisbursed facility plus committed borrower capital is enough to finish the remaining work.

These tests can point in different directions. A project can have a conservative 60% as-complete LTV but still be short of cash because the budget increased after approval. Conversely, a project can be fully funded to completion but exceed a lender’s acceptable leverage against current or stabilized value.

A construction budget should not begin with the requested mortgage amount. It should begin with total uses: land or existing-property basis, hard construction, site work, professional fees, permits, development charges where applicable, taxes, insurance, financing costs, interest carry and contingency. The sources side then identifies borrower cash/equity, grants or program funds where applicable, presale deposits or other accepted sources, and the construction facility.

Existing land equity can be economically valuable, but lenders differ on how much of that value they recognize as borrower equity and when it is considered invested. Appreciation since land purchase is not automatically equivalent to new cash available to pay a contractor.

Owner-occupied residential construction may fit an insured progress-advance program, a conventional bank/credit-union construction product, an alternative lender, or a private construction mortgage. Commercial development may be financed by banks, credit unions, institutional/commercial lenders, private capital or public programs. Each can use different LTC, LTV, presale, liquidity, builder-experience, draw and takeout requirements.

CMHC Improvement is one insured homeowner/small-rental framework, not the universal rule for construction lending. CMHC currently permits progress advances for new construction and improvements above the program’s small-improvement threshold, but uninsured and private construction facilities can use entirely different leverage and draw structures.

A lender may approve a maximum construction facility while advancing only part of it at each milestone. Before a draw, the lender may require inspection evidence, updated title or lien review, invoices, proof of equity spent, statutory declarations, updated budget information and confirmation that the remaining funds can still complete the project.

This creates a recurring liquidity problem: contractors and suppliers may need payment before the lender releases the next draw. Borrower liquidity is therefore part of construction underwriting even when the completed project has substantial equity.

A construction contingency absorbs unknown project costs. An interest reserve funds some or all construction-period interest where the structure permits. A lender draw holdback is a contractual amount the lender does not release at a particular stage. An Ontario statutory holdback arises under the Construction Act and protects lien-related interests under provincial law.

Using one reserve to solve another problem can create a hidden deficit. For example, spending the entire contingency on design upgrades leaves no protection against soil, structural or mechanical surprises; using money expected for contractor holdback to pay interest can create a payment and lien problem.

Construction can stall because of budget overruns, contractor failure, permit or inspection issues, weather, material delays, title problems, environmental findings, insurance gaps, change orders, borrower liquidity depletion, labour disputes or a change in the expected permanent lender.

The severity of a delay depends on where it occurs. A two-month delay before foundations may consume carry but leave scope flexible. A two-month delay when a private construction mortgage is near maturity can create extension and refinancing risk even if the physical work itself is almost complete.

The construction lender and permanent lender may answer different questions. The construction lender may focus on land equity, budget and completion controls; the future lender may require occupancy, marketable finished condition, stable income, a completed appraisal, DSCR, business financial statements, or ordinary residential qualification.

A project is therefore not fully financed merely because the construction facility closes. The intended takeout should state what will be different at completion and whether those future facts have a reasonable chance of satisfying the permanent lender.

Construction changes both the physical property and the legal risk around it. The lender may need to understand title configuration, easements, severance, zoning, building permits, construction contracts, insurance and construction liens before releasing funds.

Ontario’s Construction Act imposes a statutory holdback regime and lien rules. Effective January 1, 2026, the Act also introduced new annual holdback-release mechanics. The interaction among lien rights, mortgage advances and priority is legally complex, so borrowers should treat lawyer/lender clearance as part of the draw process rather than as a final administrative step.

One combined “bad case” can hide which variable actually breaks the project. A more useful borrower test models at least: a cost increase, a timeline extension, a lower as-complete value, delayed takeout, and—where income property is involved—slower lease-up or lower stabilized rent.

The project is most resilient when no single moderate shock exhausts all contingency and liquidity. A project whose only solution to every adverse scenario is “the finished value should be higher” is relying on appreciation rather than controlled financing.

In one funded case, a retired Canadian Armed Forces veteran had a self-build that was not complete enough for the intended bank refinance. Short-term construction capital was used to finish the property; the permanent refinance was a separate underwriting event. In another case, two Ottawa townhouses were intended to be sold separately but remained on one title; title severance had to be resolved before two separately secured construction loans made sense.

These cases do not create lender rules. They demonstrate two durable principles: completion can be a gating condition for the next lender, and legal structure can be as important as physical progress.

Before comparing rates, identify: what exists now; what will exist when finished; total verified cost; capital already invested; money still required; how and when draws are released; what can interrupt completion; and what repays the construction debt.

If those eight answers reconcile, pricing and lender terms can be compared intelligently. If they do not, a low quoted rate does not repair the missing financing logic.
