How Much House Can I Afford Based on Your Income
A common starting point is a home price of 3–4 times your gross annual income, adjusted up or down by your down payment, existing debts, and local interest rates. The only way to get a number specific to your situation is to run your actual income, debts, and down payment through an affordability calculator rather than relying on the multiplier alone.
Every home-price rule of thumb — 3x income, 4x income, 28% of gross pay — is a rough starting point, not a personal answer. The real number depends on your specific debts, down payment, and the interest rate available to you right now, which is why working through actual examples is more useful than memorizing a multiplier.
Three worked examples
A household earning $60,000 a year, with $300 in monthly debt payments and a $15,000 down payment, at a 6.5% rate, lands in a home price range around $220,000–$250,000 once property tax and insurance are factored in — using a 36% total DTI ceiling as the guide.
At $90,000 a year with $500 in monthly debts and a $40,000 down payment, the same math points to roughly $340,000–$380,000. At $140,000 a year with minimal other debt and a $70,000 down payment, the range moves to roughly $550,000–$620,000.
The pattern across all three: down payment and existing debt move the number as much as income does — two households with identical income but different debt loads can have a $50,000+ difference in what they can afford.
Why the multiplier alone isn't enough
A flat "3x income" rule ignores interest rate entirely, which is a large omission — the same income supports a meaningfully smaller loan at 7% than at 5%, since more of every payment goes to interest rather than principal at a higher rate.
It also ignores existing debt. Someone with no car payment or student loans can typically afford a noticeably larger mortgage than someone with the same income carrying $600 a month in other debt, even though a flat income multiplier would treat them identically.
