## How Underwriters Calculate Debt To Income Ratio On Payments That Can Be Eliminated

Those who are a co-signer for a loan, that monthly payment that is reflected on credit report can be eliminated in monthly income qualification if, and only if, they have proof that they are not making that payment.

For example, here is a case scenario:

• those who have co-signed for a friend or family member on a vehicle
• and can provide canceled checks from the prior 12 months from the friend or family member
• that monthly payment can be eliminated from the monthly income qualification from mortgage application

Another example is those with student loans:

• If parents are paying the student loan payments
• and can provide 12 months canceled checks from for the payments
• those monthly payments will not be counted towards the monthly income qualification on mortgage DTI calculations

By eliminating these payments that they are not paying on will lower debt to income ratios and enable them to qualify for a mortgage loan that would have otherwise not qualified for.

• This fully amortized monthly payment amount turns out to be approximately 0.50% of the student loan balance

With VA Loans, deferred student loans that have been deferred for more than 12 months are exempt from debt to income calculations.

## Installment Loans Under 10 Months Left

Borrowers with installment debt that has less than 10 months left, the monthly debts can be excluded from debt to income calculations.

This does not apply for automobile leases and only automobile purchase loans.

## Lender Overlays On Debt To Income Ratios
