Using Rental Income to Qualify
The rental income from your investment property can help you qualify for the mortgage. But lenders don’t count 100% of it — here’s how the math actually works.
The Rental Offset
Most lenders use one of two approaches:
Add-Back Method
Add 50% of gross rental income to your qualifying income. This is common for owner-occupied multi-unit properties.
Offset Method
Use rental income to offset the carrying costs of the property (mortgage payment, taxes, heat). Commonly used for non-owner-occupied rentals.
📊 Example: Add-Back
Property rents for $2,000/month
50% counted: $1,000/month
Added to your income for qualification
What Lenders Want to See
- Market rent appraisal: Appraiser confirms what the property should rent for
- Existing leases: If already rented, provide current lease agreements
- Rental history: T1 Schedule showing past rental income (if applicable)
When Rental Income Isn’t Enough
Even with rental income offset, you’ll need strong personal income to qualify. Lenders apply the stress test to ensure you can afford the property if:
- The property sits vacant
- Rates increase significantly
- Major repairs are needed
💡 Strong Applications
Having reserves beyond your down payment strengthens your application. Lenders feel more comfortable knowing you have 3-6 months of carrying costs available.
