In this guide, we’ll explain what construction loans are, how they work specifically for custom homes in Toronto, what lenders look for, and how you can secure financing with confidence.

What Are Construction Loans for Custom Homes?
A Construction Loan for Custom Homes is a short‑term, interim financing solution designed to cover the costs associated with building a house. Unlike a traditional mortgage, which is funded as a lump sum upon closing, a construction loan is disbursed in stages, corresponding to the progress of your build.
Key Features
- Interest‑Only Payments During Construction: You typically pay only interest on funds that have been released at each stage, reducing early monthly costs.
- Draw Schedule: Funds are released in phases (e.g., foundation, framing, finishes) as certified by inspections.
- Conversion to Mortgage: Once construction is complete, the loan often converts to a traditional mortgage without needing to refinance.
A strong understanding of Construction Loans for Custom Homes helps you plan better, avoid surprises, and stay in control of your budget.
How Construction Loans Work in Toronto
Construction loans in Toronto operate differently from standard home mortgages due to the complexity and risk involved in building from scratch.
1. Pre‑Approval and Budgeting
Before lenders approve a construction loan, they usually require:
- Detailed builder quotes
- Architectural plans
- Project timeline
- Cost breakdown
They want to understand exactly how much each stage will cost and how long the build will take.
2. Draw Schedule Releases
Instead of receiving one lump sum, your funds are released as the build progresses. A typical draw schedule might look like this:
| Stage | Approx. % of Total |
| Foundation and Excavation | 15% |
| Framing | 25% |
| Mechanical & Rough‑Ins | 20% |
| Interior Finishes | 30% |
| Final Completion | 10% |
This staged release gives lenders confidence that money is being used appropriately and helps homeowners manage cash flow throughout the project.
Interest Rates and Payments Explained
During the construction period, you generally make interest‑only payments on the amount that has been disbursed so far. This means your monthly payments are lower while the home is being built.
Typical Loan Structure
- Interest‑Only Period: During construction (usually 6–18 months)
- Conversion to Mortgage: After completion when full principal + interest payments begin
Because these loans are considered higher risk than conventional mortgages, interest rates are often slightly higher. However, converting to a traditional mortgage once the home is complete may allow for lower long‑term rates.

Qualifications and Requirements
To secure a Construction Loan for Custom Homes, lenders typically evaluate the following:
Financial Requirements
- Good credit score (typically 680+)
- Stable income
- Down payment (often 20–25%)
- Debt‑to‑income ratio within acceptable limits
Project Requirements
Lenders also assess the project itself:
- Detail architectural plans
- Verified builder agreements
- Permits and approvals
- Realistic cost estimates from qualified contractors
Having these components prepared before applying increases your chances of approval and speeds up the financing process.
Common Mistakes to Avoid with Construction Loans for Custom Homes

- Unforeseen site issues
Not Getting Pre‑Approved Early
Applying for financing after beginning your project can delay approvals and slow down progress. Early pre‑approval sets expectations and prevents setbacks.
