How Suite Income Helps Qualification

Rental Income Add-Back

Some lenders: Add 50% of gross rent
Other lenders: Add 100% then subtract vacancy allowance
Result: Higher purchasing power

Example Calculation

Suite rents for $1,200/month:

Conservative approach: $600/month added to income
$600 x 12 = $7,200 annual income added
Could increase purchase power by $30,000-$50,000
