Financing a rental property

Last reviewed October 30, 2026

How you finance an income property shapes its returns more than almost anything else. Down payment rules, rental income treatment and qualification all differ depending on whether you'll live in the property. Here's how it generally works in Canada. Your lender or mortgage broker has the final word.

Owner-occupied vs investment

These are general patterns. Lenders and mortgage insurers set their own criteria, so confirm with a lender who regularly finances rental properties.

How lenders count rental income

Lenders typically use one of two methods:

• Add-back: a percentage of the rental income is added to your personal income for qualifying.
• Offset: a percentage of the rental income is subtracted from the property's costs (mortgage, taxes, heat).

The percentage and method vary by lender and by whether the property is owner-occupied. For existing rentals, lenders may want to see leases, and for income you've been earning, your tax returns showing rental income. For new rentals, they may use an appraiser's estimate of market rent.

The stress test applies

Federally regulated lenders qualify you at a stress-test rate, generally the higher of 5.25% or your contract rate plus 2%. Your existing obligations, including your current home's mortgage if you're keeping it, count against you. That's often what limits investors buying a second or third property.

Buying a second property

If you own your home and want to buy a rental:

• Use your equity: a HELOC or refinance on your home can fund the rental's down payment. Interest on money borrowed to earn rental income may be tax-deductible, so talk to an accountant about structuring and tracing it properly.
• Mind your ratios: adding a second mortgage plus the rental's costs can push your debt service ratios over limits, even with rental income counted.
• Keep reserves: lenders and common sense both favour investors with cash reserves for vacancies and repairs.

Refinancing to add units

Since January 2025, federal mortgage insurance rules allow eligible homeowners to refinance insured mortgages to help fund building secondary suites, within program limits. If you're planning an additional residential unit, ask your lender whether this or a purchase-plus-improvements mortgage fits.

Five or more units

Properties with five or more units are financed as commercial real estate, with different underwriting based mainly on the property's income (debt service coverage), different down payment requirements, and CMHC multi-unit programs for some projects. It's a different world, so work with a commercial mortgage broker.

Choosing a term and rate

For investors, the main risk is renewal at a higher rate. Consider:

• Running your cash flow analysis at a higher renewal rate.
• Fixed vs variable based on your cash buffer and risk tolerance.
• Prepayment privileges and penalties, especially if you might sell or refinance.
• Portability, if you might sell one property and buy another.

Insurance lenders will ask about

Lenders require proper insurance before funding. A rental needs a landlord or rental dwelling policy, not a standard homeowner policy, and a house hack needs coverage that reflects the rented unit. Get quotes during your conditional period, because some insurers have restrictions on older wiring, oil tanks or student rentals.

Your financing team

A mortgage broker with rental experience can compare lenders' rental income policies, which differ more than most people realise. Pair that with an accountant for structure and a real estate lawyer for the purchase.
