Construction & development financing

Commercial construction is underwritten as a project lifecycle—not a one-time mortgage approval

Commercial construction finance funds a changing project whose cost, collateral value and future repayment engine all have to remain supportable until completion and stabilization or sale.

Commercial construction finance should be viewed as a sequence of risk states

A commercial project may move through land acquisition, zoning/entitlements, servicing, construction, lease-up or business occupancy, stabilization, and permanent financing or sale. Different capital providers may participate at different stages because the collateral and repayment source change as the project advances.

The construction facility is therefore one part of a capital plan, not necessarily the permanent debt.

The finished project must have a credible permanent repayment engine

For an income-producing development, the permanent engine is usually stabilized NOI and acceptable DSCR. For an owner-occupied facility, it may be operating-business cash flow. For a condominium or townhouse development, repayment may depend materially on unit sales. Mixed-use and specialized properties can combine several engines.

Construction lending is weakest when the project can be built but there is no reliable answer to who will hold, buy or refinance the completed asset.

Commercial construction is constrained by cost and value at the same time

Loan-to-cost measures debt against recognized project cost. Loan-to-value measures debt against accepted collateral value. A lender may also test land value, as-is value, as-complete value and stabilized value separately.

A project whose market value rises faster than cost can still face an LTC cap. A project that fits LTC can still fail if appraisal or stabilized value does not support the completed leverage.

Senior construction debt is only one possible source in the project capital stack

Project sources can include land equity, sponsor cash, senior construction debt, subordinate debt where permitted, preferred or common equity, grants/incentives and—in sale developments—accepted purchaser deposits or sales proceeds under the lender’s rules.

The borrower should understand the priority, repayment and control rights attached to each source. More capital does not always mean more usable completion liquidity if a source is conditional, subordinated or unavailable until a later milestone.

How and when sponsor equity is invested can matter as much as the percentage

Some lenders expect identified sponsor equity to be invested before or alongside senior advances. Others use negotiated pari passu or milestone structures. There is no universal Canadian “equity first” formula.

The economic purpose is straightforward: the lender wants a sufficiently funded project and meaningful sponsor capital at risk. Borrowers should model the actual draw agreement rather than assume that approved equity can remain untouched until completion.

Commercial construction capital is also advanced in stages as the project creates value

Commercial construction financing is not ordinarily a single lump-sum advance. The committed facility may be large, but actual debt is released progressively as the sponsor invests required equity, work is completed, costs are verified and the lender or project monitor confirms that enough capital remains to finish the project.

One draw pattern we have encountered in practice begins with an advance of roughly 65% of the accepted as-is value. Where the site is bare land, the starting reference can therefore be the accepted land value rather than the hoped-for completed value. The sponsor uses that early capital, together with required equity, to move through site preparation, excavation, servicing and foundations before additional construction value exists.

Illustrative second draw — structure: a subsequent advance may follow completion of foundations and material progress on walls, framing, structural components and roofing.

Illustrative third draw — weather-tight milestone: another draw may become available when the building envelope has advanced far enough to protect the structure from weather, commonly involving the roof, windows, exterior doors and related envelope components.

Illustrative fourth draw — building systems and interiors: later capital may fund drywall, floors and substantial plumbing, electrical, mechanical/HVAC and other interior systems as the building moves toward functional completion.

Illustrative fifth or completion-stage draw — finishes and site completion: the final construction stages may include paint, vanities and fixtures where applicable, trim, remaining finishes, landscaping, site works, deficiencies and other items required for occupancy, substantial completion, stabilization or permanent takeout.

This sequence is an illustrative field pattern, not a prescribed commercial draw schedule. The approximate 65% first-draw LTV is not a universal lender maximum or minimum. A commercial lender may instead constrain the first and later advances through LTC, as-is LTV, cost-to-complete, equity-in requirements, presales or pre-leasing, project-monitor certificates, lien/holdback requirements and its own risk policy. Projects can have materially fewer or more draws, and the same physical milestone may produce a different advance depending on the remaining budget and undisbursed facility.

Commercial budgets require both development and financing costs

Hard costs include the physical work. Soft costs can include architecture, engineering, consultants, permits, development charges, municipal/utility work, marketing/leasing, legal, appraisal/environmental work and project management. Financing costs can include interest, fees, inspections, quantity-surveyor or consultant costs and extension exposure.

Construction interest is itself sensitive to the draw curve. A project that advances faster or runs longer than expected can consume materially more interest reserve even if the physical budget remains unchanged.

Independent project monitoring converts a budget into evidence of progress

Commercial lenders commonly use architects, engineers, quantity surveyors, cost consultants or other inspectors to confirm percentage completion, invoices, change orders, remaining cost and whether the undisbursed facility is sufficient. The exact professional and report scope depend on the project and lender.

The monitor is not simply valuing completed bricks and concrete. The more important question at each draw is often whether remaining capital still exceeds credible remaining cost.

Pre-sales and pre-leasing can support a project without eliminating completion risk

For-sale development may rely on presales to demonstrate demand and support repayment. Rental or commercial projects may rely on pre-leasing to support future NOI. Lenders can discount contracts that are conditional, related-party, concentrated, weakly deposited or far above market.

A signed future lease is not cash flow today, and a presale is not equivalent to completed sale proceeds. Both are evidence about future demand whose quality must be assessed.

Public rental-construction programs are a separate policy pathway, not the commercial market default

CMHC’s Apartment Construction Loan Program currently offers low-cost construction-to-stabilization financing for eligible rental projects, with a minimum loan size of $1 million and at least five rental units under its standard-rental stream. CMHC states that financing can reach up to 100% of the cost of the residential component for qualifying projects.

Those are program-specific maximums, coupled with eligibility, affordability/social-outcome, documentation, borrower capability, construction-experience, stabilization and takeout conditions. They should not be generalized into “commercial developers can borrow 100% of cost.”

Specialized-use construction adds permanent marketability risk

A place of worship, hotel, health facility, purpose-built manufacturing plant or other specialized asset may have a thinner resale market than a standard industrial or multi-residential building. If the project stalls, the lender may inherit a partially complete asset with even fewer alternative users.

The financing therefore has to consider both construction completion and completed-property marketability.

Permanent takeout should be sized from stabilized facts, not construction optimism

For an income property, test realistic stabilized NOI, DSCR, cap rate/appraisal and permanent LTV. For an owner-occupied project, test normalized business cash flow and the completed mortgage payment. For a sale development, test net sale proceeds after remaining costs and release requirements.

A lower permanent mortgage than expected creates a takeout gap that must be filled with equity, sale proceeds, subordinate capital where permitted, or a smaller construction balance before maturity.

A specialized funded project illustrates why “commercial construction” is not one lender category

A Brampton place of worship required multi-million-dollar construction financing. The difficulty was not only loan size: specialized-use collateral and construction risk narrowed lender appetite simultaneously. Temporary private construction financing was used because the project did not fit ordinary conventional execution.

The borrower-facing lesson is that lender fit changes with property use, stage and exit. Specialized collateral should be analyzed for the permanent market before construction debt is sized around the hoped-for finished value.

Sources and verification

BDC, CMHC, appraisal and Ontario construction-law sources anchor the public framework. Commercial construction leverage, equity timing, presale/prelease thresholds, monitoring and guarantees remain lender- and project-specific.
