How It Works

DTI is a screening metric used by lenders to gauge repayment capacity under current obligations.

A high DTI can increase approval difficulty and reduce margin for financial shocks.

Improving DTI usually requires lowering recurring debt payments, increasing income, or both.

Outcome

DTI is 35%, near common benchmark zones used in underwriting.

Scenario
