DSCR for Canadian Rental Properties: What Lenders Look For

The Debt Service Coverage Ratio (DSCR) is the metric lenders use to assess whether a rental property can support its own mortgage. It's also one of the most useful tools for investors to evaluate a deal objectively — a single number that tells you whether the property pays for itself. Here's how to calculate it, what lenders require in Canada, and how to improve yours.

What Is DSCR?

DSCR measures how many times a property's net operating income (NOI) covers its annual debt service (mortgage payments). A DSCR of 1.0 means the property exactly breaks even — rental income covers the mortgage, nothing more. A DSCR of 1.25 means income is 25% higher than the mortgage payment.

What Canadian Lenders Require

Important: Some lenders apply the B-20 stress test rate (contract + 2%) to the DSCR calculation, not the actual contract rate. This makes it even harder to achieve the minimum DSCR — and is one reason why many investors use private lenders for initial acquisition.

How to Improve Your DSCR

Increase NOI

• Raise rents to market rate: If existing tenants are paying below market, rent increases (within provincial rent control rules) can materially improve DSCR.
• Add income streams: Laundry, parking, storage, or utilities included in rent.
• Reduce vacancies: Better tenant screening, faster unit turnover, more attractive units.
• Reduce operating expenses: Negotiate insurance, energy efficiency improvements to reduce utility costs.

Reduce Debt Service

• Make a larger down payment: Less mortgage = lower annual debt service.
• Negotiate a lower interest rate: A 0.5% rate reduction on a $400K mortgage reduces annual payments by ~$1,200.
• Choose a shorter amortization: This increases payments and worsens DSCR — but reduces total interest. Use it only if your DSCR has room to absorb it.

Frequently Asked Questions

Can I use personal income to offset a low DSCR?

For traditional mortgages, lenders evaluate rental properties on their own DSCR. However, for your first or second investment property, many lenders will also consider your personal income (salary) in a "blended" qualification approach. As you accumulate more properties, lenders rely increasingly on the DSCR of the rental portfolio itself.

Is DSCR the same as cash-on-cash return?

No. DSCR compares NOI to debt service — it tells you whether the property covers its mortgage. Cash-on-cash return compares annual cash flow (NOI minus debt service) to the total cash you invested — it tells you the return on your equity. A property can have a DSCR of 1.1 but a negative cash-on-cash if operating expenses eat the surplus. Use both metrics together.
