Rental Offset

“Rental offset” is the percentage of rental income a borrower receives that the lender is willing to use to qualify him/her for a mortgage.

Rental offset is typically 50-80%, with a limited number of lenders allowing up to 100% on conventional mortgages.  This percentage of rental income isdeducted from the borrower’s debts to determine his/her debt ratio.

Here’s an example of how rental offset is used to calculate a borrower’s total debt service (TDS) ratio:
PITH + Other Debts – ( Rental Offset x Rental Income )

Borrower’s Income
PITH  =  Principal, interest, property taxes, heat, and 1/2 of condo fees. PITH generally takes into account housing costs from all the borrower’s properties.

Keep in mind, lenders have many different forumulas for calculating debt ratios with rental income, so check your lender’s guidelines.
