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 $150,000 income, that's $3,500/month max.
- 36%: Total debt payments (housing + car loan + student loans + credit card minimums) should not exceed 36% of gross income. For your scenario: $4,500 − $1,200 existing debt = $3,300 available for housing.
- Below 28%/36% gives you breathing room. Above signals stress.
