The 28% front-end cap limits housing costs; the 36% back-end cap limits housing plus all other debt payments — whichever bites first sets your budget (the tool shows which). Many lenders stretch to 43-50% DTI, but the 28/36 zone is where homeownership stays comfortable. A bigger down payment or paying off a car loan directly raises your price range. Estimates only.
