Ever wondered if your debts are blocking your home dream? My sister Lisa had $1,500 monthly debt on $5,000 income, and her DTI was 30 percent, barely qualifying for FHA. In 2025, with lenders capping DTI at 43 percent, a DTI calculator is your key to qualifying. At MortgageTune.com, we’ve created this tool to help you check DTI for zero down loans. This guide explains how to use it, why it’s vital, and tips to lower DTI. Let’s dig in.
