The 28/36 rule explained

Standard lender affordability rule used by most US mortgage underwriters:

  • 28%: Housing payment (PITI) should not exceed 28% of gross monthly income. For $100,000 income, that's $2,333/month max.
  • 36%: Total debt payments (housing + car loan + student loans + credit card minimums) should not exceed 36% of gross income. For your scenario: $3,000$600 existing debt = $2,400 available for housing.
  • Below 28%/36% gives you breathing room. Above signals stress.
