What is the Income Needed for a $600k Mortgage?


Thinking about buying a $600,000 home? Before you start browsing listings, you’ll want to know if your income can support a mortgage that size. The income needed for a $600k mortgage depends on several key factors like your down payment, credit score, debt, and interest rate.

Whether you’re eyeing a suburban home in Denver, CO or a townhome in San Diego, CA, understanding how lenders evaluate affordability can help you set realistic expectations and make smarter financial decisions.

The short answer

  • Most homebuyers will need to earn between $140,000 to $180,000 per year to afford a $600,000 home.



  • Of course, that number can change based on your credit score, existing debt, and monthly expenses.



  • This estimate assumes a 30-year fixed mortgage, average interest rates, and a moderate down payment.

What is the income needed for a $600k house?

Lenders typically suggest that your total monthly housing expenses – mortgage, taxes, insurance, and any HOA fees – stay under 28% to 31% of your gross monthly income. To stay within those limits, you’ll likely need to make between $11,700 and $15,000 per month or around $140K to $180K per year, depending on your financial profile. The key factors that affect this number include:

  • Loan interest rate



  • Down payment size



  • Property taxes and insurance costs



  • Your existing monthly debts



  • Your credit score

Example scenario

Let’s assume the following:

  • Home price: $600,000



  • Down payment: 20% ($120,000)



  • Loan: $480,000 with a 30-year term at 6.75% interest



  • Monthly costs: ~$3,113 (includes mortgage, taxes, insurance)

Estimated monthly mortgage payment (principal + interest): ~$3,113

Total estimated monthly housing cost: $3,113 + $595 + $270 = $3,978

Based on this example, your gross monthly income should be around $14,200, or about $170,500 annually, to stay within the recommended affordability range.
