Real estate investment can be a powerful wealth-building strategy, but financing rental properties comes with different rules than primary residences. Here's your complete guide to investment property mortgages in Canada.

Key Differences: Investment vs Primary Residence

Primary Residence

  • ✓ 5% minimum down payment
  • ✓ CMHC insurance available
  • ✓ Lower interest rates
  • ✓ Easier qualification
  • ✓ Tax-free capital gains

Investment Property

  • • 20% minimum down payment
  • • No mortgage insurance
  • • Rates 0.15-0.50% higher
  • • Stricter qualification
  • • Rental income taxable

Down Payment Requirements

Minimum Down Payments for Investment Properties:

  • 20% - Single investment property (1st rental)
  • 20% - Second investment property
  • 25%+ - Third and subsequent properties
  • 35%+ - Some lenders require this for multiple properties

How Lenders Calculate Rental Income

Lenders use rental income to help you qualify, but they don't count 100% of it. Here's the typical calculation:

Rental Income Formula

Step 1: Monthly rent × 50% (offset expenses) = Net rental income

Step 2: Add net rental income to your employment income

Step 3: Calculate debt ratios with combined income

Example:

Monthly rent: $2,000

Lender counts: $2,000 × 50% = $1,000/month

This $1,000 helps you qualify for more!

Types of Investment Property Loans

Single Rental Property Mortgage

Standard mortgage for your first investment property. 20% down, rental income can help qualification.

Multi-Unit Financing (2-4 units)

Finance a duplex, triplex, or fourplex. Live in one unit, rent the others. Can qualify with as little as 5-10% down if you occupy one unit.

Portfolio Financing

Special programs for investors with multiple properties. May offer better rates but require larger down payments (25-35%).
