How much house can I afford with $100,000 income?

Using the 28/36 rule: conservative target $300,000 (28% of gross to housing only), aggressive ceiling $230,000 (36% to total debt). Recommended middle: $265,000 — leaves room for emergencies and lifestyle.

What's the monthly payment at this price?

At $265,000 home price with 10% down ($26,500) at 7% for 30 years: PITI is $2,057/month. Breakdown: P&I $1,587, taxes $221, insurance $110, PMI $139.

What's my debt-to-income (DTI) ratio?

Housing DTI: 25% (target <28%). Total DTI: 39% (target <36%). Most lenders cap DTI at 36-43% depending on loan type. FHA allows up to 50% in some cases; conventional is stricter.

Is this realistic in today's market?

In 2026, US median home price is ~$420K and 30-year mortgage rates hover 6.5-7.5%. The $265,000 target above assumes 7% rate. In high-cost-of-living markets (Bay Area, NYC, Boston), the same income buys ~30-40% less. In low-COL areas (Midwest, Sun Belt suburbs), the same income often buys MORE than the 28/36 rule suggests.

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 − $1,200 existing debt = $1,800 available for housing.
Below 28%/36% gives you breathing room. Above signals stress.
