Rental & Investment Property

Some lenders prefer 25% for rentals, especially for borrowers with multiple properties or in markets they consider higher-risk. The more you put down, the better rate you'll get and the easier qualification becomes. If you're pulling the down payment from your primary home's equity (via refinance or HELOC), you need to qualify for BOTH mortgages simultaneously.

Two main approaches: (1) Rental offset — the rental income reduces the property's GDS impact (mortgage + tax + heat - rental income). (2) Add-back — a percentage of rental income is added to your personal income for TDS calculation. Some lenders use 50% of market rent, others use 80%. If you have a signed lease at $2,500/month, a lender using 80% counts $2,000 vs one using 50% counting $1,250. That difference changes the deal. A broker routes you to the most favorable method.

Lenders verify occupancy intent. If you say it's a second home but immediately rent it out, that's misrepresentation — it can trigger a full recall of the mortgage. Be honest upfront. Some lenders have hybrid products for properties that are part-time personal use and part-time rental (like a cottage you rent in summer). The classification affects your rate, down payment, and qualification.

The challenge: Airbnb income is volatile and seasonal. Lenders prefer predictable long-term lease income. If you have 2+ years of Airbnb hosting history (tax returns showing the income), some lenders will count it. Without a track record, they'll qualify you on your personal income alone and treat the property as if it generates zero rent. Calgary and Canmore are popular Alberta Airbnb markets — but municipal regulations vary. Check local bylaws before buying specifically for short-term rental.

The cap isn't just about number of properties — it's about total debt and how lenders stack the qualifying ratios. Each additional property adds complexity. With 3+ rentals, some lenders require a property portfolio schedule showing income and expenses for each. The math gets tighter with each property because lenders stress-test ALL mortgages simultaneously. This is where a broker who specializes in investor financing makes a massive difference.

Example: Your home is worth $600,000, you owe $350,000. Refinance to $480,000 (80% LTV) = $130,000 in extracted equity. That's 20% down on a $650,000 rental property. You now have two mortgages — your refinanced primary at ~$480,000 and the rental at ~$520,000. You must qualify for both at the stress test rate, with the rental income offset helping. This is leveraged investing — powerful but requires discipline.

Lenders stack all properties: your primary home's GDS costs + each rental's net costs (carrying costs minus rental income offset) all go into the TDS calculation. If a rental generates $2,000/month but costs $2,500/month to carry, the $500 shortfall counts against you. If it generates $2,500 and costs $2,000, the offset varies by lender — some count the surplus as income, others just zero out the property. The "best" lender for property #2 might be different from property #3 or #4.

A duplex, triplex, or fourplex where you occupy one unit is treated as an owner-occupied property, not a rental investment. This is one of the best strategies for first-time investors — buy a duplex, live in one side, rent the other. You get CMHC-insured rates with 5% down, and the rental income from the other unit helps you qualify. As you build equity, you can move out and rent both sides, then repeat with another property.

The rate premium varies by lender and market conditions. Some lenders offer the same rate for rental and owner-occupied if your file is strong (high credit, low LTV, proven rental income). Others always charge more. With B-lenders, the rental premium can be higher (0.25–0.50% more). A broker compares all options — sometimes the lender with the lowest owner-occupied rate isn't the cheapest option for a rental.

You report rental income and expenses on the T776 form with your personal tax return. Common deductible expenses: mortgage interest (not principal), property taxes, insurance, repairs and maintenance, advertising for tenants, property management fees, legal and accounting fees, and travel to the property for management. You can also claim Capital Cost Allowance (CCA/depreciation) on the building — though this has implications at sale. Consult an accountant for your specific situation.

Realistic budget: mortgage payment + property tax (monthly) + insurance (~$150/month) + maintenance reserve (5–10% of rent) + vacancy reserve (3–5% of rent) + property management if applicable (8–10% of rent). If rent is $2,500 and total carrying cost is $2,300, your cash flow is $200/month — but you're also building equity and potentially benefiting from appreciation. Slightly negative cash flow can still be a good investment if the equity growth and tax benefits outweigh the monthly shortfall.

The key challenge: you must qualify for BOTH mortgages simultaneously. The rental income from your old home helps offset its carrying costs, but you still need enough income to support both properties at the stress test rate. You should also notify your current lender that you're converting to a rental (some mortgage terms require owner occupancy — check your contract). Insurance must switch from homeowner to landlord coverage. And notify CRA about the change in use for tax purposes.
