Income needed

Keeping the full housing payment near 28% of gross income — the standard front-end lending guideline — and allowing a rough amount for taxes and insurance, a $400,000 mortgage points to a household income of about $137,017 a year. Existing car or student-loan payments lower that ceiling through the 36% total-debt rule.
