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.
