Qualification rules, rates, stress test requirements, rental offset, and a complete investment mortgage payment calculator
Financing an investment property in Canada is more complex and more expensive than financing your primary residence. Lenders apply stricter qualification standards, higher rates, and require larger down payments for investment properties. Understanding these rules — and how to work within them — is fundamental to building a Canadian real estate portfolio.
Investment properties that you will not occupy as your primary residence require a minimum 20% down payment. CMHC high-ratio mortgage insurance is not available for non-owner-occupied investment properties. This 20% minimum applies to all investment property purchases regardless of purchase price.
Exception: owner-occupied 2–4 unit properties qualify for CMHC insurance with as little as 5% down (duplex) or 10% down (triplex/fourplex), as long as you occupy one unit.
All investment property mortgages in Canada must pass the mortgage stress test — you must qualify at the higher of your contract rate + 2% OR 5.25%. This means if you're getting a 5.79% mortgage, you qualify at 7.79%. This significantly reduces your maximum borrowing capacity compared to the actual payment you'll make.
Lenders allow a percentage of your projected or actual rental income to offset the mortgage payment for qualification purposes. The percentage varies by lender and rental income type:
| Lender Type | Rental Offset Allowed | Notes |
|---|---|---|
| Major bank (A lender) | 50–80% | Of market rent or actual rent |
| Credit union / B lender | 80–100% | More flexible on rental offset |
| Owner-occupied multi-unit (CMHC) | Up to 100% | Of market rent |
| Owner-occupied basement suite | 50–100% | Depends on lender |
| Mortgage Type | Typical Rate Range | Premium vs Primary Residence |
|---|---|---|
| 5-year fixed (investment) | 5.49–6.49% | +0.10–0.30% |
| 3-year fixed (investment) | 5.29–6.29% | +0.10–0.25% |
| Variable rate (investment) | Prime −0.5 to +0.5% | +0.15–0.40% |
| HELOC (rental financing) | Prime +0.5–1.0% | Higher but interest-only |
Investment property mortgage rates carry a small premium over primary residence rates — typically 10–30 basis points with major banks. Credit unions and monoline lenders may offer more competitive investment rates. Always use a mortgage broker to compare across multiple lenders.
Mortgage interest on a loan used to purchase or improve an investment property is fully deductible against rental income in Canada. This is one of the most valuable deductions available to Canadian landlords. On a $500,000 mortgage at 5.79%, your first year's interest is approximately $28,950 — a deduction that offsets significant rental income.
The interest must be on money borrowed specifically to earn rental income. If you refinance your investment property and use the proceeds for personal purposes (vacation, personal investment), the interest on those funds is NOT deductible. Track the purpose of every dollar borrowed carefully.
