Rental income from an existing or subject property can offset your mortgage costs and improve your TDS ratio — but lenders apply a haircut (typically 50-80% of gross rent) and require 2 years of rental history for existing properties.

Rental income can meaningfully improve your mortgage qualification when handled correctly — but every lender applies it differently.

Types of Rental Income

1. Existing Rental Property You Own

  • A-lenders: Typically apply 50% of gross rental income to offset carrying costs (the "rental offset" method). Some use 80% with an operating expense deduction.
  • Documentation: 2 years of T1/T2 tax returns showing rental income, and current signed lease agreements.
  • No history yet: If the property is vacant or newly acquired, lenders typically use market rent from an appraisal — at a 50% offset.

2. Subject Property with a Rental Suite

  • For purchases where you'll occupy one unit and rent another (duplex, basement suite):
    • CMHC insured: 50-100% of rental income can be added to your qualifying income (varies by insurer)
    • A-lenders conventional: Usually 50% of market/actual rent is offset against the GDS/TDS cost
  • "Rental offset" vs "rental income": The offset method reduces your housing costs; the income method adds to your income. Offset is more conservative but widely accepted.

3. Airbnb / Short-Term Rental

  • Treated with significant skepticism — most A-lenders require 2 years of T1 history showing STR income. B-lenders may accept 1 year with booking records.

Key Rules

  • Investment property: Always requires 20% minimum down payment regardless of purchase price.
  • Owner-occupied with suite: Can qualify with standard down payment if you occupy the primary unit.
