DTI = debts/income*100; Front-end = housing/income*100; Back-end = (debts+housing)/income*100

How does this work?

DTI is monthly debts divided by gross monthly income. Front-end is housing only, back-end is all debts including housing. Lenders use both.

Conventional: front-end <28%, back-end <36% ideal, up to 45-50% allowed with good credit. Higher DTI means higher risk.

For YMYL mortgage, DTI over 43% is often cutoff for qualified mortgage. Reduce debts or increase income to lower DTI before applying.
