Plain-English explanation

Lenders add up all housing-related costs — not just the loan payment — to evaluate affordability. This figure feeds directly into ratios like the front-end debt-to-income ratio used during underwriting.

Why it matters

Underestimating monthly housing expense by focusing only on principal and interest can lead to surprises about true affordability.

Educational and illustrative only

A common misunderstanding

Monthly housing expense is not the same as the mortgage payment alone — it captures the full cost of housing, often abbreviated as PITI plus HOA.
