If your bank has turned you down for a residential mortgage because your debt ratios are too high, don’t give up. There’s another option: commercial financing. It works completely differently — and that difference could be the key to scaling your real estate portfolio.
The Core Difference: Property Income, Not Personal Income
Here’s the fundamental shift: residential mortgages focus on you. Commercial mortgages focus on the property.
When you apply for a residential mortgage, the lender calculates your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios based on your personal income — then runs the stress test. If your personal numbers are maxed, you’re done, regardless of how well your properties cash flow.
Commercial financing reverses this entirely. The lender asks one central question: can this property generate enough rental income to cover its costs? Your personal debt ratios become largely irrelevant.
This is similar to how DSCR loans for foreign nationals work in the US market — the property needs to stand on its own.
How DSCR Qualification Works
The key underwriting metric in commercial lending is the Debt Service Coverage Ratio (DSCR). Here’s the formula:
DSCR = Net Operating Income (NOI) ÷ Annual Debt Service
If a property generates $120,000 in NOI per year and your total mortgage payments are $100,000 per year, your DSCR is 1.20. Most conventional commercial lenders require a DSCR of 1.20 to 1.30. CMHC MLI Select requires just 1.10.
A DSCR above 1.0 means the property earns more than it costs to carry. A DSCR below 1.0 means you’d be covering shortfalls out of pocket — most lenders won’t touch that.
What Is NOI and How Do Lenders Calculate It?
Net Operating Income (NOI) is the property’s gross rental revenue minus all operating expenses — before mortgage payments.
Operating expenses typically include:
- Property taxes
- Insurance
- Utilities (if landlord-paid)
- Property management fees (typically 8-10%)
- Maintenance and repairs
- Reserve for replacement
NOI does not include mortgage payments (that’s what you’re solving for), depreciation, or income taxes.
Lenders will scrutinize your NOI assumptions carefully. They typically apply a vacancy allowance (5-10%) against your gross rents regardless of current occupancy, and they’ll use market rents rather than above-market leases to stress-test the income.
Example:
| Line Item | Amount |
|---|---|
| Gross Potential Rent (12 units × $1,500) | $216,000 |
| Less: Vacancy (5%) | -$10,800 |
| Effective Gross Income | $205,200 |
| Less: Operating Expenses (35%) | -$71,820 |
| Net Operating Income | $133,380 |
With a DSCR requirement of 1.20, this property could support annual debt service of up to $111,150 — roughly a $1.6M mortgage at current rates.
Property Types That Qualify for Commercial Financing
Commercial financing in Canada covers a much broader range of properties than most investors realize. The key threshold is five units — properties with five or more residential units are classified as commercial.
Multi-Family Residential (5+ Units)
Apartment buildings, purpose-built rentals, and mixed-income housing. This is the most common category for investors using commercial financing to scale. CMHC’s MLI Select program specifically targets this property type.
Office Properties
Class A, B, and C office buildings. Underwriting focuses heavily on tenant credit quality, lease terms, and weighted average lease expiry (WALE). For more detail, see our office building investment guide.
Retail Properties
Strip malls, neighbourhood shopping centres, and standalone retail. Vacancy risk and anchor tenant strength are key underwriting factors. See our retail property investment guide for an overview.
Industrial Properties
Warehouses, distribution centres, and light manufacturing. Industrial is currently a strong performer due to e-commerce demand. Lease terms tend to be longer, which improves financing terms.
Mixed-Use
Buildings combining residential and commercial uses. Lenders will underwrite residential and commercial components separately, often applying different cap rates to each income stream.
Agricultural and Specialized
Farm properties, hospitality, self-storage, and other special-purpose assets. These require specialized lenders and underwriting — not all commercial lenders cover these categories. For hospitality specifically, our hotel mortgage financing guide covers RevPAR-based qualification and lender options.

Types of Commercial Lenders in Canada
Not all lenders are created equal. Understanding the lender landscape helps you target the right source of financing for your project.
Schedule A Banks (Big Six)
The major chartered banks (RBC, TD, BMO, Scotiabank, CIBC, NBC) all have commercial lending arms. They typically offer the best rates for strong deals but have conservative underwriting criteria, require strong borrower experience, and are slower to close. Good for established investors with proven track records.
Credit Unions
Credit unions like First West Credit Union, Meridian, and provincial cooperatives often offer more flexibility than the big banks. They’re relationship-focused, understand local markets, and can be more creative on deal structure. Strong option for smaller multi-family deals.
Life Insurance Companies (Life Cos)
Sun Life, Great-West Life, and Manulife all have commercial mortgage arms. Life companies are known for very competitive long-term rates (10-25+ year terms) and high-quality underwriting. They typically require larger deal sizes ($3M+) and strong stabilized properties.
CMHC (Canada Mortgage and Housing Corporation)
CMHC doesn’t lend directly — it insures commercial mortgages originated by approved lenders. CMHC programs dramatically reduce lender risk, enabling lower rates and higher leverage than conventional financing. The flagship program for investors is MLI Select (see below).
Mortgage Investment Corporations (MICs) and Private Lenders
MICs and private lenders bridge gaps that institutional lenders won’t fill: construction-to-permanent transitions, value-add properties mid-renovation, borrowers with credit issues, or projects with short track records. Rates are significantly higher (8-14%), but they solve problems that conventional lenders can’t.
Bridge Lenders
Specialized short-term lenders (6-18 months) used to stabilize a property before placing permanent financing. Common for acquisitions requiring immediate improvements, lease-up periods, or repositioning.
The CMHC MLI Select Program
For Canadian investors in multi-family housing, CMHC MLI Select is one of the most powerful financing tools available. Here’s what makes it exceptional:
Key terms:
- Up to 95% loan-to-cost financing (5% equity required)
- Amortization up to 50 years
- DSCR requirement of just 1.10
- Significantly reduced insurance premiums for properties meeting energy efficiency and affordability criteria
The 50-year amortization is the real differentiator. On a $3M mortgage at 5%:
- 25-year amortization = ~$17,500/month payment
- 50-year amortization = ~$13,500/month payment
That $4,000/month difference adds $48,000/year to your cash flow — and strengthens your DSCR ratio, making it easier to qualify.
MLI Select uses a points system based on three categories:
- Energy efficiency — building to or above energy codes
- Affordability — percentage of units below median market rent
- Accessibility — units designed for seniors and people with disabilities
Higher points unlock lower insurance premiums (as low as 0.25% of the loan amount vs. the standard 2.75-4.0%).
This program is especially well-suited to Edmonton’s rental market, where median rents (~$1,665 as of early 2026) combined with reasonable construction costs create strong NOI for purpose-built rental projects.
Who Should Look at Commercial Mortgages?
Commercial financing makes sense for:
- Investors whose residential debt ratios are maxed — you can’t get another residential mortgage, but a property with strong NOI may qualify commercially
- Self-employed borrowers — commercial lending cares less about T4 income than residential; NOI is what matters
- Investors targeting 5+ unit buildings — these fall under commercial rules regardless of your preference
- Developers building rental housing — CMHC MLI Select is purpose-built for this
- Portfolio investors looking to consolidate — blanket commercial mortgages can wrap multiple properties
Single-family rentals typically fall under residential rules. The commercial door opens at five units.
Get Pre-Qualified on the Property, Not Just Yourself
A common mistake investors make: they find a property, get it under contract, then apply for financing. Four to six weeks later, they find out it doesn’t work.
Smart commercial investors do this backwards. They get the property pre-analyzed first. A good commercial mortgage broker can turn around a preliminary underwriting within 24 hours and tell you:
- Whether the NOI supports the purchase price
- Which lender type is best suited to the deal
- Whether CMHC programs apply
- What the likely terms and rates will look like
This saves you from tying up time and deposit money on deals that won’t close.
With CMHC MLI Select’s 1.10 DSCR threshold and 50-year amortizations, the numbers can be surprisingly achievable — book a strategy call and we’ll run the property through our underwriting model before you make an offer.
Working With the Right Team
Experience in commercial lending matters far more than in residential. A commercial mortgage broker who has personally done the transactions you’re trying to do understands:
- Which lenders are appetite-matched to your deal
- How to structure the pro forma to reflect lender expectations
- How to navigate CMHC submissions and timelines
- What’s negotiable and what isn’t in commercial term sheets
Compare that to a residential broker dabbling in commercial deals — the difference in outcome can be millions of dollars in financing or months of wasted time.

Amortization
The period over which a mortgage is scheduled to be fully paid off through regular payments of principal and [interest](/glossary/interest-rate). In Canada, common amortization periods are 25 or 30 years, though the mortgage term (when you renegotiate) is typically 1-5 years. A longer amortization lowers monthly payments, improving [cash flow](/glossary/cash-flow) but increasing total interest paid.
CMHC Insurance
Mortgage default insurance from Canada Mortgage and Housing Corporation. For 1-4 unit investment properties, investors must put 20%+ down (no insurance available). However, CMHC offers MLI Select for 5+ unit multifamily properties, and house hackers can access insured mortgages with 5-10% down.
Cash Flow
The money left over after collecting rent and paying all expenses including mortgage, taxes, insurance, maintenance, and property management. Positive cash flow is the primary goal of buy-and-hold investors. See also [NOI](/glossary/noi), [Cash-on-Cash Return](/glossary/cash-on-cash-return), and [Vacancy Rate](/glossary/vacancy-rate).
DSCR
Debt Service Coverage Ratio - a metric that compares a property's [net operating income](/glossary/noi) to its mortgage payments. A DSCR of 1.25 means the property generates 25% more income than needed to cover the debt. Lenders typically require a minimum DSCR of 1.0 to 1.25 for investment property loans. See also [Cap Rate](/glossary/cap-rate) and [Cash Flow](/glossary/cash-flow).
Down Payment
The upfront cash payment when purchasing a property. For 1-4 unit investment properties, minimum 20% down is required. 5+ unit multifamily can use CMHC MLI Select with lower down payments, and house hackers can put as little as 5% down on owner-occupied 2-4 plexes. Your down payment directly affects your [LTV](/glossary/ltv) and the amount of [leverage](/glossary/leverage) you use.
Interest Rate
The cost of borrowing money, expressed as a percentage. It determines how much you pay on top of the principal borrowed. Interest rates directly affect monthly payments, [cash flow](/glossary/cash-flow), and [DSCR](/glossary/dscr). See also [Amortization](/glossary/amortization).
LTV
Loan-to-Value ratio - the mortgage amount expressed as a percentage of the property's appraised value or purchase price (whichever is lower). An 80% LTV means you're borrowing 80% and putting 20% [down](/glossary/down-payment). Lower LTV generally means better [interest rates](/glossary/interest-rate) and terms. See also [Equity](/glossary/equity) and [Leverage](/glossary/leverage).
Single Family
A detached home designed for one household, the most common property type for beginner real estate investors.
Blanket Mortgage
A single mortgage that covers multiple properties, often used by investors to simplify financing for a portfolio. Allows release of individual properties as they're sold.
Mortgage Broker
A licensed professional who shops multiple lenders to find the best mortgage rates and terms for borrowers. Unlike banks, brokers have access to dozens of lending options.
Coverage Ratio
A measure of a property's ability to cover its debt payments, typically referring to DSCR. Commercial lenders often require a minimum of 1.2, meaning the property's net operating income exceeds debt payments by at least 20%.
CMHC MLI Select
A CMHC program offering reduced mortgage insurance premiums and extended amortization (up to 50 years) for multifamily properties with 5+ units that meet energy efficiency or accessibility standards. Popular among investors scaling into larger apartment buildings.
