Affordability is a scenario, not a verdict.

The calculator reserves the selected share of gross monthly income for housing after subtracting other monthly debt, then solves for the highest home price whose modeled payment fits that budget.

This is not lender underwriting or a recommendation to borrow. It does not model credit, closing costs, income taxes, utilities, maintenance, reserves, loan limits, or lender-specific DTI rules.

Before you use the number.

What does housing DTI mean here?

It is the share of gross monthly income reserved for the modeled housing cost in this scenario. The calculator subtracts other monthly debt before solving for a price.

Does the result mean I qualify for that home price?

No. Qualification depends on credit, documentation, loan program, reserves, lender rules, and costs this illustration does not model.
