What Triggers Commercial Requirements?

In British Columbia, lenders require you to move from residential products to commercial mortgage structures when the property or borrower intent hits specific thresholds:

5+ Unit Residential: Any building with five or more self-contained units.
Investment Intent: Properties where the borrower has zero intention of personal occupancy.
Asset Class: All retail, office, industrial, hotel, and warehouse properties.
Mixed-Use: Buildings where commercial lease income is a dominant component of the NOI.
Development: Any raw land acquisition or active construction project.

Note: Attempting to use a residential mortgage on a commercial asset is considered mortgage misrepresentation in BC.

Comparison FAQ

Can I buy commercial property with a residential mortgage?

Generally, no. Commercial assets carry different title designations and income structures that residential products are not licensed or modeled to cover. Institutional lenders strictly regulate asset-specific debt.

Is it harder to qualify for a commercial mortgage?

It is different, not necessarily harder. Commercial qualification focuses on the property's income. This is often advantageous for investors with modest personal income but access to high-yield commercial assets.

Do I need a larger down payment?

Yes, significantly. While residential can be as low as 5%, commercial acquisitions typically require 25% to 35% down. The exception is CMHC MLI Select apartment deals, which can go as low as 15%.

Is the interest tax deductible?

Yes. For BC commercial investment properties, mortgage interest is generally deductible against the property's rental income. Consult with a BC-based tax professional for your specific corporate structure. Learn more.
