Category: House Affordability

House Affordability quantifies the maximum purchase price and mortgage debt a prospective buyer can responsibly service based on gross household income, monthly debt obligations, down payment capital, and prevailing mortgage interest rates, without exceeding strict underwriting debt-to-income (DTI) thresholds.

The 28/36 Rule, PITI Components & Mortgage Underwriting

Mortgage underwriting evaluates affordability through two primary ratios: the front-end ratio and the back-end ratio. The gold standard in conventional lending is the 28/36 rule. The front-end ratio dictates that total monthly housing expenses—comprising Principal, Interest, Property Taxes, and Homeowners Insurance (PITI)—must not exceed 28% of gross monthly income.

The back-end ratio stipulates that all recurring debt obligations combined (PITI plus student loans, automobile financing, minimum credit card payments, and child support) must remain under 36% of gross income. While FHA and VA programs permit back-end ratios extending up to 43% to 50% with compensating factors, exceeding 36% drastically reduces household discretionary cash reserves.

Frequently Asked Questions

What components make up the monthly PITI payment?

PITI represents the four mandatory monthly housing costs: Principal (paying down loan balance), Interest (lender financing cost), Taxes (local municipal property assessments), and Insurance (hazard and homeowners coverage, plus PMI if down payment is below 20%).

Why do mortgage interest rates heavily alter purchase power?

A 1% increase in mortgage interest rates reduces a buyer’s purchasing power by roughly 10 percent. On a $300,000 mortgage, an interest rate increase from 6% to 7% elevates monthly principal and interest payments by over $200 per month.
