Audit Monthly Debts

Tally minimum monthly card payments, auto loans, and student loans. Do NOT include groceries or utilities.

2026/2027 Guidelines

Frequently Asked Questions: Home Affordability & DTI

Grounded in current FHFA conforming guidelines, Fannie Mae standards, and credit underwriting benchmarks.

Conventional lenders evaluate two primary benchmarks: the Front-End DTI ratio (housing payment including Principal, Interest, Taxes, and Insurance / PITI should ideally be ≤28% of gross monthly income) and the Back-End DTI ratio (housing payment plus all recurring personal debts should not exceed 43%). The qualifying loan is strictly bounded by whichever ceiling is hit first.
