DSCR is the single most important underwriting metric in BC commercial financing. It determines whether your property qualifies for institutional debt, exactly how much a lender will advance, and which specialized programs remain available for your asset.
Debt Service Coverage Ratio (DSCR) measures your property's ability to pay its own mortgage out of its net income. Unlike residential lending, where your personal T4 income leads the deal, commercial lenders prioritize the asset's cash flow. Every BC commercial borrower should understand:
DSCR = Net Operating Income / Annual Debt Service
The fundamental commercial qualification test
Below 1.20x Institutional Floor
In this scenario, the borrower would need to reduce the loan amount or increase NOI to qualify.
BC lenders apply the minimum DSCR as a "hard floor." If a deal falls below the threshold, the loan amount is automatically restructured downwards until the ratio is met.
Lenders normalize expenses against BC market norms to ensure your NOI is sustainable. Review our Valuation Guide for more on NOI data.
If your deal is sitting thin on coverage, we help you deploy specific actions to move it into qualifying institutional territory:
Bringing rents to market value, reducing controllable expenses, or adding auxiliary income streams (e.g., parking or storage).
Lowering the principal requested reduces the annual debt service, instantly mathematically improving the coverage ratio.
Accessing longer schedules (up to 40 years) reduces the principal component of the payment, lowering debt service.
Locking into a shorter-term fixed rate can sometimes reduce the lender’s stress-test buffer in specific yield curve conditions.
For standard BC institutional deals, the floor is 1.20x to 1.25x. Some regional credit unions may offer slight flexibility on stabilized assets in strong markets.
Yes. Even with a large down payment, if the requested loan amount does not produce a DSCR above the lender's floor, the file will be declined or the loan amount further reduced by the underwriter.
Rarely. DSCR is a property-specific income metric. Adding a co-borrower with high outside income doesn't change the property's NOI, which is the primary driver for institutional commercial debt.
CMHC allows for 40-year amortization. This significantly lowers the annual debt service payment for the same loan amount, allowing a deal with lower NOI to qualify for much higher leverage.
