DTI

How do student loans count in conventional DTI?

Short answer

The repayment status and conventional program matter. Fannie Mae may accept a documented $0 income-driven payment; that is different from its treatment of deferment or forbearance.

Plain-English explanation

What this actually means.

For Fannie Mae, use the supported current payment when appropriate. A documented $0 income-driven payment may be counted as $0; a deferred or forborne loan uses 1% of the balance or a documented fully amortizing payment. Freddie Mac generally requires a positive amount and uses 0.5% when the report shows $0 unless the file supports a different current positive payment. Upcoming income recertification or payment changes need review under the applicable rules.

Practical example

A simple example

On an $80,000 balance, Fannie Mae’s 1% method would count $800 a month, while Freddie Mac’s 0.5% method would count $400. A documented $0 income-driven payment can be different under Fannie Mae. The lender must identify the repayment status before choosing the calculation.

Illustration only. This is not an approval or a loan offer.

What can change the answer?

Where this can move.

Fannie Mae, Freddie Mac, FHA or another program; repayment versus deferment or forbearance; current statements; upcoming payment changes; and lender requirements.
