How AffordHomeUSA estimates affordability

Debt-to-income framework

A common starting point for affordability is the 28/36 rule. Under that framework, housing costs are generally targeted at roughly 28% of gross monthly income, while total monthly debt obligations are generally targeted at roughly 36% of gross monthly income. This is a planning heuristic, not a guarantee of loan approval.

Monthly housing cost assumptions

Affordability estimates should be based on full monthly ownership cost, not principal and interest alone. Where relevant, that includes:

• Principal and interest
• Property taxes
• Homeowners insurance
• PMI or FHA mortgage insurance
• HOA dues when applicable

Users should also budget separately for maintenance, repairs, and cash reserves, even when those costs are not embedded directly in a loan payment.

State and city context

State pages and location-based articles use housing and cost-of-living context maintained in the site’s structured state dataset. Those values are intended to provide comparison context, not a precise citywide appraisal standard or a substitute for current listing-level pricing.

Scenario modeling

Salary ranges and affordability scenarios in blog articles are directional educational estimates built from home prices, taxes, and typical debt-to-income logic. Actual loan approval depends on borrower credit, lender overlays, employment history, reserves, property type, and current market pricing.

How to use the site correctly

Start with the Home Affordability Calculator to estimate a range, compare loan structures in the Mortgage Calculator, and then review relevant blog and state pages to understand taxes, cost of living, and local tradeoffs.
