How Much House Can I Afford on a $120,000 Salary?

$120,000 a year is a common household income for dual-income professional couples, and it's also a realistic single salary for many mid-career specialists. Whether it's one paycheck or two combined, the lender's math treats it the same: under the standard 28/36 rule, this income supports a home priced between $492,211 and $553,738. The more interesting question at this income level isn't whether you qualify. It's how much of that approved amount you should actually spend.

The 28/36 math

Monthly gross income on $120,000 works out to $10,000. Lenders cap housing costs at 28% of that, or $2,800 a month, and total debt including the mortgage at 36%, or $3,600 a month. At 6.5% on a 30-year fixed loan, a $2,800 payment supports a loan of roughly $442,990. With 10% down, that puts the home price around $492,211. With 20% down, the same monthly payment stretches to a $553,738 home, since less of the purchase price needs financing.

What this budget buys

A $492,000 to $554,000 range covers a comfortable single-family home in most mid-sized US metros, often with room to spare for updates or a bigger lot. In higher-cost cities like Denver, Austin, or parts of the Northeast, the same budget lands you in a solid but not luxurious home, and in the priciest coastal markets it may only cover a condo. As with any income bracket, run the numbers against your specific city before assuming national averages apply.

Should you max out your approval, or buy under budget?

This is the real decision many $120,000 buyers face, because unlike lower incomes where the 36% ceiling is often the binding constraint, at this level plenty of buyers genuinely qualify for more house than they need. Stretching to the full $553,738 approval means a $2,800 monthly commitment that leaves less room for retirement contributions, an emergency fund, or simply discretionary spending. Buying at, say, $475,000 instead keeps the payment meaningfully lower and preserves the ability to keep maxing out a 401(k) or IRA. Before deciding, it's worth running your full retirement math through the retirement calculator to see what a smaller monthly mortgage payment, redirected into retirement savings instead, actually compounds to over 20 or 30 years. For a lot of buyers at this income, that comparison is the deciding factor, not the lender's approval letter.

15-year vs 30-year: a real number comparison

On a $442,990 loan at 6.5%, the 30-year payment is about $2,800 a month in principal and interest. Switch to a 15-year term and the rate typically drops slightly, but the shorter term still pushes the payment up substantially, to roughly $3,800 to $3,900 a month at a representative 15-year rate near 6%. That's an extra $1,000-plus a month committed to the house rather than invested elsewhere, in exchange for paying off the loan in half the time and cutting total interest paid by more than half. At $120,000 income, a 15-year term is often affordable within the 36% ceiling, but it does trade flexibility for speed, so weigh it against how much you value liquidity in the next 15 years.

Debt still matters at this income

Even at $120,000, a car payment or student loan reduces what's left for the mortgage under the 36% ceiling. A buyer with $600 a month in other debt only has $3,000 left for housing before hitting the total debt cap, below the $2,800 the 28% rule alone would allow. Paying down revolving debt before applying is one of the fastest ways to raise your approved amount without changing your income at all.

Recap

A $120,000 income supports a $492,211 to $553,738 home under standard lending rules, with a $2,800 monthly housing payment. The bigger decision is whether to buy at the top of that range or leave room for retirement savings and a shorter loan term.
