Is a $450,000 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 $2,395/month (30-year, 7%, 20% down), you would need a gross monthly income of at least $8,554 (annual: $102,647) to keep housing costs at 28% of income.
A 15-year mortgage at 6.75% costs $3,186/month but saves $288,811 in total interest over the life of the loan compared to 30 years.

Tips for Buying a $450,000 Home
- Save for 20% down ($90,000). This eliminates PMI and gives you the best rates. If that's too much, FHA loans start at 3.5% down ($15,750).
- Shop rates aggressively. Even 0.25% lower on a $360,000 loan saves $60/month — that adds up to $21,649 over 30 years.
- Budget for closing costs. Expect 2-5% of the purchase price ($9,000–$22,500) 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 $3,186/month instead of $2,395, you'll own your home in half the time and save $288,811 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.
