Is a $900,000 Home Affordable?

A common rule of thumb is that your home should cost no more than 3× your annual income, and your monthly payment should be no more than 28% of your gross monthly income.

At $4,790/month (30-year, 7%, 20% down), you would need a gross monthly income of at least $17,108 (annual: $205,293) to keep housing costs at 28% of income.

A 15-year mortgage at 6.75% costs $6,371/month but saves $577,621 in total interest over the life of the loan compared to 30 years.

Tips for Buying a $900,000 Home

  • Save for 20% down ($180,000). This eliminates PMI and gives you the best rates. If that's too much, FHA loans start at 3.5% down ($31,500).
  • Shop rates aggressively. Even 0.25% lower on a $720,000 loan saves $120/month — that adds up to $43,298 over 30 years.
  • Budget for closing costs. Expect 2-5% of the purchase price ($18,000$45,000) in closing costs on top of your down payment.
  • Don't forget ongoing costs. Property taxes (1-2%), homeowners insurance, maintenance (1% of home value/year), and possibly HOA fees all add to your monthly obligation.
  • Consider the 15-year option. If you can handle $6,371/month instead of $4,790, you'll own your home in half the time and save $577,621 in interest.
  • Get pre-approved first. A pre-approval letter strengthens your offer and locks in a rate for 60-90 days while you shop.
