$120,000 is roughly 50% above the US median household income — firmly upper-middle class in most of the country, and enough for a comfortable home nearly anywhere outside the priciest metros. Using the lending industry's standard 28/36 rule, the answer lands around $415k–$460k depending on your debts, down payment and rate. Here is the exact math.
The 28/36 rule, step by step
Lenders use two ratios:
- Front-end (28%): Housing costs ≤ 28% of gross monthly income
- Back-end (36%): All monthly debts ≤ 36% of gross monthly income
On $120,000/year ($10,000/month):
- Front-end limit: $10,000 × 0.28 = $2,800/month for housing
- Back-end limit: $10,000 × 0.36 = $3,600/month for everything
If you have $700/month in car and student loan payments, the back-end rule allows $3,600 − $700 = $2,900 for housing, so the front-end $2,800 is the binding limit.
Converting the payment to a price
At 6.5% on a 30-year loan, $2,800/month in principal and interest supports a loan of about $443,000. With 20% down, that means a home price of roughly $554,000, but wait. That $2,800 must also cover property taxes and insurance (PITI), which lenders include in "housing." After ~$480/month for taxes and insurance, the P&I budget is closer to $2,322, supporting a loan of ~$367,000 and a price of ~$460,000 with 20% down.
Realistic ranges on $120K salary:
| Down payment | Approx. max home price (6.5%, 30-yr) | |---|---| | 10% down | ~$415,000 | | 20% down | ~$460,000 | | Debts over $1,200/mo | subtract ~$65,000 |
Five things that move the number
- Interest rate. At 5.5% instead of 6.5%, the same payment buys ~12% more house. Rate matters more than most buyers think.
- Existing debts. Every $200/month in debt payments cuts roughly $30,000 off your max price. Killing a car payment before buying is powerful.
- Down payment. On $120K, 20% down is very achievable, and putting down more starts to make real sense — every extra $50,000 down cuts roughly $316/month off the payment at 6.5%.
- Property taxes. In New Jersey, taxes on a home in this range can top $1,000/month; in Texas, ~$700; in Colorado, under $300. Location changes affordability enormously.
- HOA dues. A $300/month HOA fee counts against your ratios exactly like a higher mortgage payment.
The costs buyers forget
The mortgage is only the headline. Budget ~1% of the home's value per year for maintenance ($4,600/year on a $460,000 home), plus utilities, and an emergency fund that covers 3–6 months of the new higher housing cost, not your old rent. Higher price means higher stakes on the inspection and appraisal — a $1,000 inspection on a $450K purchase is rounding error.
Should you max it out?
The 28/36 rule is a ceiling, not a target. On $120K it's tempting to stretch — but buying 10–20% below your max leaves room for investing, travel and life. Being "house poor" at a high income is just lifestyle inflation with a mortgage.
