Can I afford a $400 k house on a $100 k salary?


Editorial team Published on

Yes, you can afford a $400,000 house on a $100,000 salary, but it will be tight and depends heavily on your down payment and other debts.

A $100,000 salary gives you a gross monthly income of about $8,333. Traditional lending rules and comfortable budget guidelines view this scenario differently:

What the Numbers Look Like

  • Monthly Gross Income: $8,333
  • Estimated Monthly Housing Payment: A $400,000 home (with a standard down payment and current interest rates) typically results in a monthly payment of $2,300 to $2,700 for principal, interest, taxes, and insurance.
  • The 28/36 Rule: Financial guidelines suggest spending no more than 28% of your gross monthly income ($2,333) on housing. A $400k home pushes slightly past this conservative limit depending on your exact rate and property taxes.
  • Bank Approval vs. Reality: Banks may approve you for a higher loan amount based on debt-to-income ratios up to 43%–50%, but doing so can leave you "house poor".

Key Factors That Make It Work

  • Down Payment: Putting down 10% to 20% significantly lowers your monthly mortgage payment and helps you avoid expensive private mortgage insurance (PMI).
  • Other Debts: Having car payments, high student loans, or credit card debt makes a $400k house much harder to manage on a $100k salary.
  • Location: Local property taxes, homeowner's insurance rates, and HOA fees vary widely by region and change your bottom-line monthly cost.
