DTI guidelines at a glance
Front-end ≤28% and back-end ≤36% is ideal. FHA allows up to 43% back-end. VA and some conventional loans allow 45–50% with strong credit.
DTI is one factor in mortgage qualification. Lenders also consider credit score, assets, employment history, and loan type. Consult a licensed mortgage professional.
