Construction Financing

Construction lenders apply two distinct tests when sizing a loan, and understanding both is essential for accurately forecasting how much financing you can access. The lower of the two calculations governs — whichever test produces the smaller loan amount is the binding constraint.

Loan-to-Cost (LTC)

LTC measures the loan amount as a percentage of the total project cost — the sum of every dollar invested in the project, including land, hard construction costs, soft costs, financing costs, and contingency. Most lenders advance 65 to 75 percent of total project cost.

Example: Total project cost of $8,000,000 × 70% LTC = maximum loan of $5,600,000. The borrower must contribute the remaining $2,400,000 in equity.

LTC is the primary sizing tool in early-stage underwriting because the total cost is known before the project is built. It ties the lender’s exposure directly to actual investment in the project.

Loan-to-Value (LTV) — As-Complete

LTV measures the loan amount as a percentage of the projected completed value of the finished project — what the property will be worth once built and stabilised, as estimated by an independent appraiser. Most lenders apply a test of 65 to 75 percent of the appraised value.

Example: As-complete appraised value of $9,500,000 × 70% LTV = maximum loan of $6,650,000. In this case, LTC is the binding constraint at $5,600,000.

In practice, the two tests interact in ways that matter for project planning. A development project in a strong market — where the as-complete value significantly exceeds total cost — will typically be LTC-constrained, meaning the borrower’s equity requirement is set by the cost of building the project. A project in a compressed or uncertain market — where projected value is close to or below total cost — may become LTV-constrained, meaning the appraiser’s view of completed value limits what the lender will advance, regardless of how efficiently the project is built.

For developers planning a project budget, running both calculations before approaching a lender gives a realistic picture of the equity required, avoiding surprises during the underwriting process.

LTV ensures the loan does not exceed a prudent percentage of the collateral value, protecting the lender if the market shifts or the project is realised below its projected cost.

A construction project budget is one of the most scrutinised documents in a construction loan application. Lenders use it to size the loan, calibrate the draw schedule, and assess whether the project is financially viable. A budget that is incomplete, internally inconsistent, or missing standard cost categories signals inexperience and directly affects how lenders view the application.

A complete construction project budget for a commercial development in Canada is structured around three main categories:

Hard Costs

• Site preparation, demolition, and earthworks $480,000
• Foundation and structural work $1,850,000
• Building envelope (exterior walls, roofing, windows) $1,420,000
• Mechanical, electrical, and plumbing systems $1,680,000
• Interior finishes and fit-out $920,000
• Site works, landscaping, and parking $350,000
• Total Hard Costs $6,700,000

Soft Costs

• Architectural and engineering fees- $420,000
• Municipal permits, development charges, and levies – $310,000
• Legal and title costs – $95,000
• Project management and construction oversight – $200,000
• Marketing, leasing, or sales costs – $130,000

Total Soft Costs $1,155,000

Financing and Carrying Costs

• Construction loan interest (interest reserve)$480,000
• Lender and broker fees$165,000

Contingency

• Hard cost contingency (7.5% of hard costs)$502,500

An interest reserve is a portion of the approved construction loan set aside to cover interest payments during the construction period. Rather than requiring the borrower to service the loan with external cash flow during months when the project generates no revenue, the lender pre-approves a budget for interest costs and automatically draws from it as interest accrues on the outstanding loan balance.

It works as follows. At the time of loan approval, the lender and borrower agree on an interest reserve amount — calculated based on the projected draw schedule, the loan’s floating rate, and the expected construction timeline. This reserve is built into the total approved loan amount, not funded separately. As each draw advances and the loan balance grows, interest accrues on the drawn balance. That interest is deducted from the reserve rather than requiring a cash payment from the borrower.

How the reserve is calculated

The interest reserve is modelled against the projected draw schedule. On a project where draws increase steadily over 18 months at a rate of prime plus 1.75%, the average outstanding balance over the construction period — weighted for when each draw occurs — drives the total interest cost. Lenders typically add a buffer to the calculated reserve to account for rate movements or timeline slippage.

Simple illustration: On a $6M construction loan drawn evenly over 18 months at 8% all-in, the average outstanding balance is approximately $3M. Interest cost ≈ $3M × 8% × 1.5 years = $360,000 interest reserve.

What happens if the reserve runs out

If the construction period extends beyond the projected timeline or if interest rates increase materially above the reserve assumption, the interest reserve can be depleted before the project reaches completion. When that happens, the borrower must fund interest payments from external sources — or negotiate an increase to the reserve, which requires lender approval and may require additional equity.

This is one of the most common sources of cash flow stress on construction projects. Modelling the interest reserve against a downside timeline — six months longer than the base case — is prudent planning before any loan is advanced.

Not all construction loans include a built-in interest reserve. Some lenders advance the interest reserve as part of the total loan facility; others require the borrower to service interest from their own cash during construction. This structural difference affects the borrower’s equity requirement and cash flow planning significantly, and it is one of the key variables to compare when evaluating competing construction loan term sheets.

A construction holdback is a mandatory retention of a percentage of each draw advance — typically 10 percent — that the lender holds back until the statutory lien period under provincial construction or builders’ lien legislation has expired. The holdback exists to protect subcontractors, suppliers, and other parties who have contributed labour or materials to the project and have the right to file a lien against the property if they are not paid.

The holdback is not a fee. It is the borrower’s money — held in trust by the lender until the lien exposure is cleared. Once the lien period closes and the lender is satisfied that no valid liens have been filed, the holdback is released to the borrower. The timing of that release, and the specific legislative requirements that govern it, vary by province.

The practical cash flow impact is significant on larger projects. On a $6 million construction loan with a 10 percent holdback, up to $600,000 of approved loan funds are withheld from the borrower at any given time during construction. The borrower and their general contractor must plan for this gap — subcontractors will expect payment from the GC for completed work, and if the GC has not accounted for the holdback lag in their own cash flow, payment disputes can arise that create project delays.

Key points for borrowers:

• The holdback applies to each draw individually — it is not calculated once at the end. On each draw advance, 10 percent is retained, and the holdback balance accumulates throughout the project.
• Substantial performance matters. In Ontario specifically, the lien period clock on the holdback starts running from the date a Certificate of Substantial Performance is published — a step that requires deliberate action by the project owner. Delays in publishing the Certificate extend the period before the holdback can be released.
• Lenders will not release the holdback until the lien period has expired and a clean title search confirms no liens are filed. Budget for the holdback release to occur 6 to 10 weeks after substantial completion — not at the same time as the final draw.

Cost overruns are one of the most common and most stressful events in commercial construction, and how they are handled depends heavily on how the loan was structured at the outset, the lender’s relationship with the borrower, and how early the overrun is identified. The earlier the problem surfaces, the more options the borrower has. Overruns discovered in the final third of a project, when draws are nearly exhausted and leverage to renegotiate is limited, are the most difficult to resolve.

Option 1 — Borrower Equity Injection

The most straightforward resolution. The borrower funds the overrun from their own capital — cash reserves, equity in other assets, or available credit — without requiring any change to the construction loan. This is why lenders value borrower liquidity and net worth as part of underwriting: sponsors who can absorb a 10 to 15 percent cost overrun independently represent a substantially lower risk than those who cannot.

Option 2 — Loan Increase (Cost Overrun Facility)

Some construction loans include a pre-approved cost overrun facility — a separate tranche of financing available if costs exceed the approved budget by a defined threshold, typically five to ten percent. Lenders who offer this structure will have assessed the as-complete value to confirm headroom exists. This must be negotiated into the original facility — it cannot typically be added after the fact.

Option 3 — Supplemental Private or Mezzanine Financing

If the primary lender cannot or will not increase the facility, and the borrower’s own capital is insufficient, additional capital can be raised from private lenders or mezzanine providers. These sources move faster than institutional lenders and can step in to fund overruns. The cost of this capital is higher, and its availability depends on the lender holding the first mortgage being agreeable to junior financing, not always guaranteed.

What happens if overruns go unaddressed

If a borrower cannot fund an overrun and the approved loan is exhausted before the project is complete, the lender will typically stop advancing funds. An incomplete building is illiquid collateral — difficult to sell, often impossible to refinance, and generating no income. This scenario is the most severe outcome of an underfunded project, and it is why lenders require meaningful contingency reserves and why pre-funding that contingency realistically in the budget is not optional.

The most effective protection against overrun exposure is budget discipline at the start. Engage a quantity surveyor to independently validate hard cost estimates before submitting the application. Fund a contingency of at least seven to ten percent of hard costs — not as a line item that lenders can choose to exclude, but as a genuine reserve the borrower understands they may need. And structure the loan with enough flexibility — through an overrun facility or committed borrower liquidity — to absorb variance without triggering a funding crisis.

Take-out financing is the term loan or permanent mortgage that replaces the construction loan once the project reaches completion and stabilisation. Construction loans are short-term instruments — typically 12 to 36 months — and they are explicitly not designed to be held long-term. The take-out is the lender’s exit from the construction exposure, and demonstrating a credible path to take-out financing is a prerequisite for most institutional construction lenders before they will advance a single dollar.

The type of take-out financing depends on the project type:

Multi-Family Rental

CMHC-insured financing through the MLI Select program is the most common and most favourable take-out for eligible multi-family rental developments. The CMHC take-out can be committed at the construction stage — providing the developer with certainty on the permanent financing before the project is built. Cedar Commercial arranges both the construction facility and the CMHC take-out in coordinated sequence.

Income-Producing Commercial

Conventional institutional term financing — from a bank, credit union, or life company — is the standard take-out for stabilised industrial, retail, office, or mixed-use assets. The construction lender will want to see a commitment letter or a strong preliminary indication from a term lender before or shortly after advancing the construction loan.

For-Sale Developments

Condominium, freehold, or land subdivision projects typically repay the construction loan through sales proceeds rather than a term mortgage. Lenders assess pre-sales coverage — the percentage of units sold under binding purchase contracts — as the primary take-out indicator. Most lenders require a minimum pre-sale threshold (often 60 to 80 percent of units) before advancing construction funds.

Planning take-out financing from day one means understanding three things before the construction loan is committed. First, what are the qualifying criteria for the intended take-out at stabilisation — the DSCR, occupancy rate, income level, or pre-sale percentage the project must achieve before term financing is available? Second, what is the realistic timeline from construction completion to stabilisation — and is the construction loan term long enough to cover both phases? Third, if stabilisation takes longer than planned, what bridge financing is available to extend the construction loan while the take-out is arranged?

Yes, but with more significant conditions than an experienced developer would face, and with a realistic understanding of what lenders require to get comfortable with an untested sponsor. First-time developers are not automatically disqualified from construction financing in Canada. What they cannot access is the full flexibility, leverage, and pricing that a proven developer with a track record commands. The gap between a first project and a third or fourth is real, and the path through it requires preparation.

What lenders look for in a first-time developer application, in lieu of a project track record:

• A credible general contractor with a strong track record on comparable projects. The GC’s experience partially substitutes for the developer’s. A first-time developer working with a well-regarded GC who has completed five similar projects reduces the lender’s execution risk considerably. This is often the single most important compensating factor.
• Higher equity contribution. First-time developers can expect lenders to advance at a lower loan-to-cost ratio — typically 60 to 65 percent rather than the 70 to 75 percent available to experienced sponsors. The additional equity requirement reflects the lender’s view of the increased execution risk and acts as a larger financial cushion if the project encounters problems.
• Strong borrower financial position. Net worth, liquidity, and the capacity to absorb cost overruns without depending on the lender to rescue the project are critical. A first-time developer who can demonstrate that they have the financial depth to weather a 15 percent cost overrun from their own resources is in a fundamentally better position than one whose equity is fully committed to the project.
• A simpler, less complex first project. A single-phase, single-asset, single-use development in an established market is a more fundable first project than a mixed-use multi-phase development in an emerging market. Scope complexity compounds execution risk, and lenders adjust their appetite accordingly.
• A well-prepared, complete application package. A first-time developer who arrives with a full quantity surveyor’s cost estimate, a signed general contract, a completed appraisal, and a clear take-out strategy is demonstrating the professional competence that compensates for the absence of a track record. An incomplete or poorly prepared application signals the opposite.
• An experienced project manager or co-sponsor. Some first-time developers bring in an experienced co-sponsor — a partner or advisor with a relevant track record — to satisfy the lender’s sponsor experience requirement while retaining the development economics. This is a legitimate and commonly used structure for the first project.

Construction financing applications are more documentation-intensive than conventional commercial mortgage applications because the lender is underwriting a project that does not yet exist. Every document in the package serves a specific underwriting purpose, and a complete, well-organised submission is the single most effective way to accelerate the approval process and demonstrate sponsor credibility.

Project Documents

• Architectural drawings and specifications — current design drawings sufficient to confirm scope, scale, and market appropriateness
• Municipal permits and approvals — building permit, rezoning approval, development permit as applicable; or a clear path to these if not yet issued
• Construction contract — signed agreement with the general contractor, including scope, fixed price or GMP, and schedule; or a detailed tender and contractor shortlist if contract is not yet executed
• Quantity surveyor report — independent cost estimate validating the project budget; required by most institutional lenders above $3M
• Project budget — detailed line-item budget covering all hard costs, soft costs, financing costs, and contingency
• Construction schedule — milestone timeline with start and projected completion dates
• Appraisal — as-complete and, for income properties, as-stabilised appraisal from a qualified commercial appraiser

Property and Market Documents

• Land ownership documents — title search and existing encumbrances; confirmation of unencumbered equity if land is already owned
• Phase I Environmental Site Assessment — required on most projects; Phase II if Phase I identifies concerns
• Market study or feasibility analysis — third-party demand analysis supporting projected rents or sale prices; required for larger or complex projects
• Pro forma financial model — projected income and expenses at stabilisation, DSCR calculation, and return metrics
• Pre-sales evidence — signed purchase contracts for for-sale projects; pre-leasing evidence or letters of intent for commercial income projects

Borrower / Sponsor Documents

• Personal and corporate financial statements (2–3 years)
• Personal net worth statement
• Tax returns — personal and corporate (2–3 years)
• Developer bio or track record summary — previous projects with scope, cost, completion date, and outcome
• Corporate structure chart — ownership and entity relationships
• Evidence of equity contribution — confirmation of funds available to meet the equity requirement

Take-Out Financing Evidence

• Pre-application or preliminary commitment from the intended term lender
• CMHC eligibility assessment or pre-screening for multi-family rental projects
• Pre-sales summary and purchase contract schedule for condominium projects
• Evidence of refinancing capacity at stabilisation based on projected NOI and current market lending criteria

Not every document is required at initial application — lenders will typically issue a term sheet based on a preliminary package and then request a complete file for full credit approval. A commercial mortgage broker prepares the application in the format and sequence that each specific lender expects, which reduces the back-and-forth that slows approval timelines and signals to lenders that the project is being managed professionally.

The distinction matters because the two products are structured differently, underwritten differently, and draw on different lender appetites. Using the wrong framing when approaching a lender — presenting a renovation as construction, or vice versa — can result in misaligned expectations and a slower or unsuccessful approval process.

In practice, the line between a significant renovation and a construction project is not always obvious, and lenders apply their own criteria. A full gut renovation of a vacant commercial building — where the structure is retained but everything inside is replaced — may be underwritten as construction financing by some lenders and as a renovation loan by others, depending on scope and cost relative to property value.

For borrowers planning significant capital improvements on an existing commercial property, the most useful first step is describing the project scope accurately and letting the lender or broker determine which product structure fits. Accurately framing the project — rather than trying to fit it into a product category — produces better results in lender conversations and avoids misaligned expectations about documentation, timeline, and advance rates.
