Getting a Mortgage for Your First Investment Property

Investment vs Owner-Occupied: Key Differences

Lenders treat investment properties more conservatively than owner-occupied homes. The logic: if you hit financial trouble, you're more likely to keep paying your primary residence than an investment property. This means stricter rules and higher rates.

Minimum Down Payment: 20%

CMHC insurance is not available for investment properties. You must put down at least 20% — no exceptions. On a $600,000 rental property, that's a minimum $120,000 down payment.

How Lenders Count Rental Income

Here's where it gets nuanced. Lenders use rental income to offset the property's carrying costs, but they don't count 100% of it. Common approaches:

• Offset method (most common): The rental income offsets PITH (principal, interest, taxes, heat). The net amount affects your TDS ratio
• Add-back method: 50–80% of gross rental income is added to your qualifying income
• Rental offset only: Some lenders simply ignore rental income and qualify on your personal income alone

The method matters enormously. Lender A might qualify you for $750,000; Lender B for $550,000 — for the same property using the same income.

Rate Premium

Expect to pay a rate premium of 0.15% to 0.50% above owner-occupied rates for an investment property. This varies by lender and LTV.

Rental Property and Your Tax Return

Rental income must be declared. You can deduct mortgage interest, property tax, insurance, maintenance, and a portion of utilities. Keep meticulous records. A CPA who specializes in real estate investment is worth the fee.

The DSCR (Debt Service Coverage Ratio)

Some commercial-style lenders for multi-unit properties underwrite using DSCR: Net Operating Income ÷ Annual Debt Service. A ratio above 1.0 means the property covers its own costs. Some lenders target 1.1–1.25x DSCR.

Multi-Unit Properties (2–4 Units)

Owner-occupied duplexes, triplexes, and fourplexes qualify for higher-ratio (insured) mortgages with as little as 5–10% down — as long as you occupy one unit. This is one of the most powerful wealth-building strategies for first-time investors: live in one unit, collect rent from the others.

Common Pitfalls

• Underestimating vacancy: Budget for 5–8% vacancy even in tight markets
• Ignoring capital reserves: Set aside 3–5% of rent for repairs and maintenance
• Overleveraging: A second mortgage on your primary residence to fund the down payment increases risk significantly
• Not getting an independent appraisal: Lenders will order one — but you should too
