How Much Salary Do You Need to Buy a House in 2026? (The 28/36 Rule Explained)

When browsing Zillow or Realtor.com, it's easy to fall in love with a home. But the most important question for any first-time homebuyer is: Can I actually afford it?

In 2026, navigating the housing market requires a firm understanding of your Debt-to-Income (DTI) ratio. The golden standard used by almost all mortgage lenders in the United States is the 28/36 Rule.

Let's break down exactly what that means and how you can figure out your required salary.

What is the 28/36 Rule?

Lenders don't just look at how much money you make; they look at how much money you keep. The 28/36 rule establishes two strict boundaries:

1. The 28% Front-End Limit: Your total monthly housing costs (Mortgage Principal, Interest, Property Taxes, and Insurance — also known as PITI) should not exceed 28% of your gross monthly income (your income before taxes).
2. The 36% Back-End Limit: Your total monthly debt obligations (housing costs PLUS credit card minimums, auto loans, student loans, child support) should not exceed 36% of your gross monthly income.

When you apply for a conventional loan, the bank will calculate your required salary against both rules. Whichever rule requires a higher salary becomes the absolute minimum you need to earn to get approved.

Example Scenario: A $400,000 Home

Imagine you want to buy a $400,000 house in Austin, Texas. You plan to put down 20% ($80,000), leaving a loan of $320,000.

Assuming an interest rate of 6.5%, an annual property tax rate of 1.8%, and home insurance of $1,200 a year, your monthly PITI would be around $2,725.

• According to the 28% Rule: You would need a gross monthly income of $9,732 (about $116,785 a year).
• But what if you have debts? If you have a $500 monthly car payment and $300 in student loans, your total monthly debt load becomes $3,525.
• According to the 36% Rule: To keep $3,525 at or below 36% of your income, you would actually need a gross monthly income of $9,791 (about $117,500 a year).

Because the 36% rule required a slightly higher income, the bank will require you to make at least $117,500 a year to qualify.
