Overview
Rental income is one of the most important components in valuing residential investment properties.
Appraisers analyze both actual and market rent to determine how income influences value, risk, financing potential and investor return.
The goal is to ensure that the property’s income performance aligns with comparable income properties in the GTA and surrounding areas.
This guide explains how rental income is evaluated, how it affects valuation and how lenders interpret income during underwriting.
Rental income influences:
• Market positioning
• Investor demand
• Cap rates
• Risk assessment
• Income approach value
• Lender qualification
• Borrower borrowing power
Whether you are buying, refinancing or evaluating performance, understanding how rental income affects value is essential.
Appraisers consider two rent figures:
- Actual Rent
This is the rent the current tenants pay.
It reflects the property’s current performance, but not always its market potential.
Actual rent is most relevant when:
• Tenancies are stable
• Leases are long term
• Rent is aligned with market rates
- Market Rent
This is the rent the property should earn based on comparable rental data.
Market rent is used when:
• Units are vacant
• Current rent is significantly below market
• Tenancies are informal
• There is no written lease
• Short term rental history is inconsistent
Appraisers analyze nearby rental listings and recent lease data to establish market rent.
How Appraisers Use Rental Income in Valuation
- Debt Service Ratios
Lenders use rental income to support borrower qualification.
If rental income is strong, borrowers may qualify for a larger mortgage.
- Accepted Portion of Rental Income
Lenders typically include:
• 50 percent to 80 percent of rental income for qualification
• 100 percent for income approach value, depending on the lender
- Legal Status Requirements
Most lenders require:
• Legal secondary suites
• Proper fire separation
• Zoning compliance
Rental income may be ignored if a suite is not legal.
- Market Rent vs Actual Rent
Some lenders prefer market rent because it is more stable and predictable.
Factors That Influence Rental Income Recognition
- Unit Condition
Well maintained units attract higher rent and stronger tenants.
- Suite Configuration
Self contained units with private entrances are more valuable.
- Location
High demand rental areas support higher rents and lower vacancy.
- Tenant Profile
Reliable, long term tenants reduce risk.
- Lease Terms
Fixed term leases are more stable than month to month agreements.
“Higher rent means higher value.”
Not necessarily. Market cap rates still control value.
“All rental income is counted by lenders.”
Only if suites are legal and meet lender requirements.
“Appraisers always use actual rent.”
Appraisers often use market rent when actual rent is outdated or inconsistent.
“Vacancy lowers value immediately.”
Not if rental demand is strong and market rent supports the income.
Do appraisers need leases to include income?
Leases help but market rent can still be used when leases are missing.
Does illegal suite income count?
Often no. Lenders may ignore the income, even if the market recognizes it.
Can market rent increase value?
Yes, if the income approach supports a higher property value.
Do lenders look at net or gross rent?
Lenders focus on net income after applying their rental offset calculation.
