Construction financing is one of the most misunderstood aspects of commercial real estate. A lot of business owners and investors assume it works like a regular mortgage—you borrow money, you get the funds, you pay it back.
Not quite. Construction loans are fundamentally different, with unique structures, risks, and requirements that you need to understand before starting a development project.
Let me walk through how construction financing actually works, what it costs, who provides it, and how to successfully navigate the process.
What Is Construction Financing?
A construction loan is interim financing used to fund the construction or major renovation of a property. Unlike a conventional mortgage where you borrow against an existing building, construction financing funds the process of creating or substantially changing a building.
Here’s the fundamental difference: With a regular mortgage, the lender has a finished, income-producing property as collateral from day one. With construction financing, the lender starts with raw land or an empty building, and over 12-24 months, their collateral gradually transforms into a finished property.
That transformation process creates risk—what if construction costs overrun? What if the contractor abandons the job? What if the finished property is worth less than projected?
Because of this risk, construction financing is more complex, more expensive, and harder to obtain than conventional mortgages.
How Construction Loans Work
Let me break down the mechanics of construction financing.
The Advance Structure
Construction loans don’t fund as a lump sum. Instead, the lender advances funds progressively as construction reaches various stages.
Here’s a typical structure:
- Initial advance: 10-15% at closing (to purchase land or begin work)
- Foundation completion: 15-20%
- Framing and rough-ins: 20-25%
- Substantial completion: 30-40%
- Final advance: 10-15% at occupancy or stabilization
The lender inspects the construction progress at each stage and releases funds based on verified completion. You don’t get the next advance until the previous stage is complete and approved.
Interest Reserves
Many construction loans include an interest reserve—money set aside within the loan to pay interest charges during construction.
Here’s why this matters: During construction, the property isn’t producing income yet. If you’re building an apartment building, you’re not collecting rent for 18 months while it’s under construction.
The interest reserve allows you to pay interest from the loan proceeds rather than out of pocket during construction.
Example: $5 million construction loan at 8% interest over 18 months = approximately $600,000 in interest during construction. The lender adds this to the loan amount, bringing total loan to $5.6 million, and uses that $600,000 to pay interest monthly as it accrues.
Cost-Plus vs. Fixed-Price Contracts
Lenders have strong preferences about your construction contract structure.
Fixed-price contracts: General contractor agrees to complete the project for a set price. The contractor absorbs cost overruns. Lenders love this because it caps costs.
Cost-plus contracts: Contractor bills actual costs plus a management fee. More flexible but exposes the owner (and lender) to cost overruns. Lenders are nervous about this.
Most lenders require fixed-price contracts from reputable general contractors, or they want substantial cost overrun reserves.
Completion Guarantees and Recourse
Construction lenders typically require personal guarantees from the developer or sponsor. If the project fails, they want recourse beyond just foreclosing on an unfinished building.
They may also require completion guarantees—legal commitments that the project will be completed even if costs overrun.
Types of Construction Financing
Construction financing comes in different flavors depending on your situation.
Land Purchase Plus Construction
You’re buying raw land and building from scratch. The loan funds both the land purchase and the construction costs.
Loan-to-cost typically: 65-75% Example: $10 million total project cost (land plus construction), lender provides $7 million, you provide $3 million equity
Stand-Alone Construction
You already own the land, and you’re just financing the construction.
Loan-to-cost typically: 70-80% Example: You own land worth $1 million, construction costs $4 million, lender provides $3.2 million, you provide $1.8 million (including your land equity)
Renovation/Rehab Financing
You own a building and you’re doing major renovations—gut rehab, addition, significant upgrades.
Loan-to-value on completed property: 70-75% Example: Building worth $2 million as-is, you’re putting $1.5 million into renovations, it will be worth $4.5 million when complete. Lender provides $3 million (67% LTV on completed value), you provide $1.5 million.
Construction-to-Permanent Loans
Some lenders offer single-close construction-to-permanent financing—one application, one approval, one closing.
The construction phase funds the building process, then it automatically converts to permanent financing when construction completes.
Advantage: One application, locked-in permanent financing rates, less hassle Disadvantage: Less flexibility, and you’re locked into one lender’s permanent financing terms
Who Provides Construction Financing?
Construction lending is specialized. Not all lenders do it, and those who do have specific criteria.
Major Banks
Banks do construction financing, but typically only for:
- Experienced developers with strong track records
- Larger projects ($5 million+)
- Pre-sold or pre-leased projects (significant commitments from buyers/tenants)
- Well-located properties in strong markets
Bank construction financing rates: 6.5-8.0% (2026)
Banks offer the best rates but the most rigid requirements.
Credit Unions
Some credit unions do construction financing for smaller local projects.
Good for: Smaller projects ($500K-$3M), local developers, projects in the credit union’s service area
Rates: 7.0-8.5%
Alternative Lenders (B-Lenders, MICs)
Alternative lenders are increasingly active in construction financing.
Good for: Borrowers who don’t meet bank criteria, smaller projects, projects with less pre-leasing, more aggressive leverage
Rates: 8.0-10%
Examples: Timbercreek, CMLS Financial, various construction-focused funds
CMHC-Insured Construction Financing
For multi-unit residential construction (apartments, condos), CMHC offers insured construction financing.
Loan-to-cost up to 85%, competitive rates because of CMHC insurance backing
Good for: Larger apartment developments, experienced developers, projects meeting CMHC criteria
Private Construction Lenders
Private lenders do construction financing but at higher costs and lower leverage.
Loan-to-cost: 60-70% Rates: 10-14%
Used when banks and alternative lenders decline, or when you need very fast approval.
What Construction Lenders Look For
Getting approved for construction financing requires demonstrating several key things.
Experience
Lenders want developers with successful construction experience. If this is your first construction project, you’ll struggle to get financing unless you partner with an experienced general contractor or co-developer.
Specifically, they want to see:
- Previous projects of similar size and type
- Track record of completing projects on time and on budget
- References from previous lenders and contractors
Strong Equity Position
Construction lenders typically require 25-35% equity from the developer. Higher risk projects require more equity.
That equity can include:
- Cash
- Land value (if you already own the site)
- Letters of credit or other liquid assets
Detailed Project Budget and Timeline
You need a comprehensive budget breaking down all costs:
- Land acquisition
- Hard costs (construction, materials, labor)
- Soft costs (permits, professional fees, insurance, financing costs)
- Contingency (typically 10% of hard costs)
The budget needs to be supported by:
- Detailed plans and specifications
- Contractor bids
- Professional cost estimates
You also need a realistic timeline with key milestones.
Pre-Sales or Pre-Leasing
Lenders love to see demand demonstrated through pre-sales or pre-leasing.
For condos: 50%+ pre-sold units significantly improves financing availability and terms
For commercial: Anchor tenants pre-leased before construction starts reduces risk
For rental apartments: Less critical, but letters of intent from prospective tenants help
Appraisal of Completed Value
The lender orders an “as-complete” appraisal showing what the property will be worth when construction finishes.
This appraisal determines the maximum loan amount. If the appraisal comes in lower than expected, your loan amount might get reduced and you’ll need more equity.
General Contractor Quality
Lenders want reputable, bonded general contractors with:
- Experience on similar projects
- Strong financial position
- Proper licensing and insurance
- Fixed-price contract
- Performance and completion bonds
If your brother-in-law is the contractor and he’s never built anything bigger than a garage, you’re not getting bank financing.
The Construction Loan Application Process
Let me walk through what actually happens when you apply for construction financing.
Pre-Qualification (Weeks 1-2)
You provide preliminary information:
- Site location and description
- Preliminary project plans
- Estimated budget
- Your experience and financial position
Lender gives initial feedback on feasibility and potential terms.
Formal Application (Weeks 3-6)
You submit full application package:
- Detailed plans and specifications (prepared by architect)
- Engineering reports
- Project budget from contractor
- Timeline and construction schedule
- Your financial statements and track record
- Market analysis (who will rent/buy the finished units?)
- Environmental site assessment
- Geotechnical report
- Legal description and zoning confirmation
- Building permits (either obtained or imminent)
Underwriting and Appraisal (Weeks 7-10)
Lender orders independent appraisal of completed value.
Lender reviews all documentation, analyzes feasibility, and structures the loan.
Lender’s construction specialist reviews the budget and timeline for reasonableness.
Commitment (Week 11-12)
If approved, lender issues a commitment letter outlining:
- Loan amount and advance schedule
- Interest rate and fees
- Conditions (permits, contractor bonds, insurance, etc.)
- Reporting requirements during construction
- Covenants and guarantees
Due Diligence and Documentation (Weeks 13-16)
You satisfy all conditions in the commitment.
Lawyers prepare all loan documents, security agreements, guarantees.
Insurance is bound (builder’s risk, general liability).
Permits are obtained.
Closing and Initial Advance (Week 17)
All documents sign, initial advance funds, construction begins.
Total timeline: 4-5 months from initial inquiry to closing is typical for bank construction financing. Alternative lenders can move faster (2-3 months), private lenders fastest (4-8 weeks).
What Construction Financing Costs
Let me give you realistic numbers for 2026.
Interest Rates
- Bank construction loans: 6.5-8.0%
- Alternative lender construction loans: 8.0-10%
- Private construction loans: 10-14%
These rates are typically floating (tied to prime rate) during construction, though some lenders offer fixed rates.
Lender Fees
- Bank: 1.0-1.5% of loan amount
- Alternative lender: 1.5-2.5%
- Private lender: 2.5-4.0%
Inspection Fees
The lender inspects construction progress before each advance.
Inspection fees: $500-$1,500 per inspection, typically 5-8 inspections during construction
Total inspection fees: $3,000-$10,000
Legal Fees
You pay for both your lawyer and the lender’s lawyer for construction financing (more complex than regular mortgages).
Total legal fees: $10,000-$25,000 depending on project complexity
Total Financing Costs Example
$5 million construction loan from alternative lender at 9% over 18 months:
- Interest during construction: $675,000 (typically added to loan via interest reserve)
- Lender fees (2%): $100,000
- Inspection fees: $5,000
- Legal fees: $15,000
- Total: $795,000 in financing costs
That’s 15.9% of the loan amount—not cheap! But this is the cost of creating a valuable asset.
Common Construction Financing Challenges
Let me tell you about the typical issues that arise.
Cost Overruns
This is the number one risk in construction. Something always costs more than expected—material prices increase, unexpected site conditions, design changes, delays.
Best practice: Build a 10-15% contingency into your budget. Lenders feel better, and you’re not scrambling if costs increase.
Timeline Delays
Construction almost always takes longer than planned. Weather, permit delays, labor shortages, supply chain issues—delays happen.
Problem: Your interest reserve was calculated for 18 months. If construction takes 24 months, you’re paying extra interest out of pocket, which can strain cash flow.
Best practice: Be conservative on timeline assumptions and maintain cash reserves for unexpected delays.
Inspection Holdbacks
Lenders typically hold back 10% of each advance until the next stage completes. This creates a cash flow mismatch—you need to pay the contractor now, but the lender won’t release the funds until later.
Solution: Make sure your contractor understands this structure and is comfortable with it, or maintain cash reserves to bridge the gaps.
Change Orders
During construction, you’ll inevitably want to change some things. But change orders cost money and extend timelines.
Lenders often view change orders suspiciously—they see it as evidence of poor planning or scope creep.
Best practice: Minimize change orders, and when you do make changes, document clearly that you have budget to cover them.
Achieving Stabilization
For rental properties, “stabilization” (typically 90-95% occupancy) is often required before the lender releases the final advance or converts to permanent financing.
If leasing is slow, you might be stuck waiting months after construction completes, paying interest from your own pocket while you lease up.
Best practice: Start leasing/marketing early, ideally before construction completes.
Transitioning from Construction to Permanent Financing
Construction loans are interim—they need to be paid off or converted to permanent financing when construction completes.
Option 1: Construction-to-Permanent (Built-In)
Some lenders offer automatic conversion from construction to permanent financing at predetermined terms.
Advantages: Certainty, one application, no refinancing hassle Disadvantages: Locked into one lender’s permanent financing terms
Option 2: Take-Out Financing (Refinance)
More commonly, you get separate construction financing, then refinance to permanent financing when construction completes.
Advantages: Shop for best permanent financing rates after construction Disadvantages: Two applications, risk that permanent financing market changes during construction
Most experienced developers prefer take-out financing despite the extra work, because it gives them flexibility to optimize permanent financing.
Real-World Construction Financing Example
Let me walk through a realistic example.
Project: New 24-unit apartment building
Total Project Cost:
- Land acquisition: $1,000,000
- Hard costs (construction): $4,500,000
- Soft costs (architecture, engineering, permits, legal, financing): $750,000
- Interest during construction: $400,000
- Contingency: $450,000
- Total: $7,100,000
Financing Structure:
- Construction loan at 75% loan-to-cost: $5,325,000
- Developer equity: $1,775,000 (25%)
Completed Value: $9,000,000 (based on appraisal)
Construction Lender: Alternative lender at 9% interest, 2% lender fees, 18-month term
Advance Schedule:
- Closing (land acquisition + start construction): $1,500,000
- Foundation complete: $1,000,000
- Framing complete: $1,200,000
- Substantial completion: $1,200,000
- Occupancy and stabilization: $425,000
During Construction:
- Developer pays contractor according to contract schedule
- Lender inspects at each milestone and releases funds
- Interest accrues and is paid from interest reserve
- Construction takes 16 months (2 months faster than budgeted)
Upon Completion:
- Building appraises at $9,000,000
- Rental leasing begins
- After 4 months, building is 92% leased
- Developer refinances to permanent financing at 75% LTV = $6,750,000
- Pays off construction loan ($5,325,000)
- Pulls out $1,425,000 in equity for next project
- Has permanent financing at 6.5% with 25-year amortization
Developer’s return:
- Initial equity: $1,775,000
- Equity pulled out at refinancing: $1,425,000
- Net equity still invested: $350,000
- Building value: $9,000,000
- Remaining mortgage: $6,750,000
- Developer’s equity: $2,250,000
Developer turned $1,775,000 into $2,250,000 over 20 months, plus pulled out $1,425,000 to invest elsewhere—very attractive return.
The Bottom Line
Construction financing is complex, expensive, and requires significant expertise to navigate successfully. It’s not for beginners or the faint of heart.
The keys to success:
- Experienced development team
- Substantial equity (25-35%)
- Detailed planning and budgeting
- Conservative timeline and cost assumptions
- Reputable contractors
- Clear take-out financing strategy
When executed well, construction financing enables you to create valuable assets and generate attractive returns that aren’t possible with buying existing properties.
