If you’ve got your eye on a $400,000 home, you’re probably asking yourself: How much house can I afford? The income needed for a $400k mortgage comes down to a few factors, like your down payment, DTI, credit score, and even your location.

Whether you’re house hunting for a condo in Boston, MA or a home in Phoenix, AZ, understanding how your finances impact affordability can help you plan wisely. In this Redfin guide, we’ll break down the numbers, factors, and tips to help you buy a $400,000 home that works for your budget.

  • Most buyers need to earn $100,000 to $135,000 per year to afford a $400,000 home.

What is the income needed for a $400k house?

The general guideline is that your total monthly housing costs should not exceed 28% to 31% of your gross monthly income. These costs typically include your mortgage payment (principal and interest), property taxes, homeowners insurance, and any HOA fees.

To estimate the income needed for a $400,000 home, you’ll need to consider your down payment amount, loan interest rate, credit score, debt-to-income (DTI) ratio, and location, since property taxes and insurance premiums vary by region.

Example scenario

Let’s assume the following:

  • Monthly costs: ~$2,522 (includes mortgage, taxes, insurance)

Estimated monthly mortgage payment (principal + interest): ~$2,022

Total estimated monthly housing cost: $2,022 + $400 + $100 = $2,522

So, in this scenario, you’d likely need to earn around $108,000 per year to comfortably afford a $400,000 home while staying within recommended housing cost limits.
