What is a Construction Mortgage?

Understanding how construction financing works in Canada

The Basics

A construction mortgage provides financing to build a new home on land you own or are purchasing. Unlike a traditional mortgage where you receive the full amount upfront, construction mortgages are disbursed in progress draws as specific building milestones are completed.

How It Works

You pay interest-only during construction on the amount drawn. Once construction is complete, the mortgage converts to a standard mortgage with principal and interest payments. The entire process typically takes 6-18 months depending on the build.

Types of Construction Mortgages

Owner-Builder

You act as your own general contractor, managing the build and hiring sub-trades directly.

Builder Contract

A licensed contractor builds your home based on your plans and specifications.

Spec Home

Building a home to sell on speculation, not as your primary residence.

Loan-to-Cost Ratio

Typically 75-85% of total build costs (land + construction)

Construction Term

Usually 6-12 months with option to extend if needed

Interest-Only Period

Pay only interest during construction, not principal
