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

Published April 20, 2026 · 5 min read

Earning $120K per year means a gross monthly income of $10,000. But how much of that can safely go toward a mortgage? In this guide, we'll use the widely-accepted 28/36 rule to estimate how much house you can comfortably afford — and what factors might push that number higher or lower.

The 28/36 Rule Explained

Lenders and financial advisors commonly recommend the 28/36 rule as a guideline for housing affordability. The rule has two parts: spend no more than 28% of your gross monthly income on housing costs (mortgage payment, property taxes, insurance, HOA fees), and keep total debt payments (housing plus car loans, student loans, credit cards) below 36% of your gross monthly income.

On a $120K salary, 28% of your gross monthly income gives you a maximum housing payment of approximately $2,800/month.

Affordability Snapshot: $120K Salary

Metric	Amount
Annual Gross Salary	$120,000
Monthly Gross Income	$10,000
Max Housing Payment (28%)	$2,800/mo
Estimated Home Price Range	$460,000 – $540,000
20% Down Payment	$92,000 - 108,000

* Estimates assume a 30-year fixed mortgage at ~7% interest rate, 20% down payment, and no significant existing debt.

What Affects How Much House You Can Afford?

The table above gives a general range, but your actual affordability depends on several key factors.

Interest rate is one of the biggest variables. Even a 0.5% difference in rate can shift your buying power by tens of thousands of dollars. At lower rates, you can afford more house for the same monthly payment.

Down payment size matters significantly. Putting down 20% means no private mortgage insurance (PMI) and lower monthly payments. A smaller down payment (like 3-5% with an FHA loan) lets you buy sooner but increases your monthly costs.

Existing debt reduces what lenders will approve. Car payments, student loans, and credit card minimums all count against you in the 36% total debt ratio. Paying down debt before buying can dramatically increase your home budget.

Property taxes and insurance vary widely by location. A home in New Jersey (with property tax rates over 2%) will cost significantly more per month than the same-priced home in Colorado (around 0.5%). Always factor in local costs.

Credit score affects your interest rate. A score above 740 typically qualifies you for the best rates, while scores below 680 may add 0.5-1.5% to your rate — reducing your buying power considerably.

Tips to Maximize Your Home-Buying Budget

There are several practical steps you can take to afford more house on your $120K salary. First, pay down existing debt — eliminating a $400/month car payment effectively adds $400 to your housing budget. Second, improve your credit score by paying bills on time and reducing credit utilization below 30%. Third, save a larger down payment to reduce your loan amount and eliminate PMI. Fourth, consider different locations where property taxes and cost of living are lower. Finally, explore first-time buyer programs — many states offer down payment assistance and reduced-rate mortgages for qualifying buyers.
