Investment Property Mortgage Rules in Canada (2026)

Investment Property Mortgage: The Key Rules

Investment properties — properties the borrower does not occupy as their primary residence — have different mortgage rules than owner-occupied properties in Canada.

The three critical differences: 1. Minimum 20% down payment (no CMHC insurance available) 2. Higher interest rates (typically 0.1-0.3% above owner-occupied rates) 3. Rental income qualification rules apply (not just employment income)

These rules apply whether the borrower is buying their first rental property or adding to an existing portfolio.

Minimum Down Payment Requirements

Investment properties in Canada require a minimum 20% down payment regardless of purchase price. CMHC, Sagen, and Canada Guaranty do not insure investment/rental properties.

Down payment by property type:

The Stress Test for Investment Properties

The OSFI B-20 stress test applies to investment property mortgages the same as owner-occupied properties: qualifying rate = max(contract rate + 2%, 5.25%).

However, because rental income is included in the qualifying calculation, the stress test impact is partially offset for investment properties with strong rental income.

Example: $800,000 rental property, 25% down ($200,000), $600,000 mortgage, 5.5% rate: • Qualifying rate: 7.5% • Monthly payment at 7.5%, 25yr: $4,361 • Gross rent: $3,500/month; 50% offset = $1,750 reduction to housing costs • Net housing costs in GDS: $4,361 + $500 tax + $150 heat - $1,750 = $3,261 • Required income at 39% GDS: $8,362/month = $100,344/year

This is a more achievable income threshold than many expect, because rental income directly reduces the qualifying burden.

How Many Investment Properties Can You Have?

Most A lenders limit the number of financed investment properties per borrower:

• Big 6 banks: Typically 1-3 financed rental properties (varies by bank) • Monolines (First National, MCAP, RMG): Often 3-5 financed properties • B lenders: More flexible, 5-10+ properties depending on portfolio strength • Private lenders: No formal limits (deal-by-deal basis)

The limiting factor is usually TDS: each additional mortgage payment adds to TDS, making qualification harder unless rental income offsets it sufficiently.

For portfolio landlords (5+ properties), CMHC multi-family insurance (for 5+ unit buildings) and commercial lending become relevant. These use net operating income (NOI) and debt service coverage ratio (DSCR) rather than personal income qualification.

Investment Property Rates vs Owner-Occupied

Investment property mortgages carry a small rate premium over owner-occupied products:

• Insured owner-occupied: lowest rate (CMHC-backed) • Conventional owner-occupied: +0.05-0.15% over insured • Investment/rental property: +0.1-0.3% over owner-occupied conventional

This premium reflects slightly higher default risk (borrowers are more likely to default on investment properties than their primary home) and the fact that investment properties cannot be CMHC-insured.

Over a 5-year term on a $600,000 mortgage, a 0.2% rate premium equals approximately $6,000 in additional interest.

Lender Requirements for Rental Properties

Beyond down payment and qualification ratios, lenders have specific documentation and policy requirements for investment properties:

Documentation: • If property has existing tenants: signed lease agreements for all units • If vacant: rental market letter from appraiser (market rent estimate) • For existing rental portfolio: T1 General Schedule 776 (rental income/loss) • Fire/property insurance confirmation

Policy requirements: • Property must be residential (1-4 units for standard mortgage products) • Property must be in Canada • Borrower must be Canadian citizen, PR, or have valid work authorization • No existing mortgages in arrears

For deals with multiple existing rental properties, most lenders require a full rental schedule showing income, expenses, and mortgage payments for each property.

Finding Investment Property Lenders with BIPS

Investment property deals require lenders who (1) allow the specific number of financed properties the borrower already has, (2) apply the rental income method that works for the deal, and (3) have the right LTV for the scenario.

BIPS filters lenders by all three criteria simultaneously. Enter the investment property scenario — rental income, existing properties, credit, LTV — and BIPS returns only lenders whose products qualify this specific deal.
