Is a $400,000 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 $2,129/month (30-year, 7%, 20% down), you would need a gross monthly income of at least $7,603 (annual: $91,241) to keep housing costs at 28% of income.

A 15-year mortgage at 6.75% costs $2,832/month but saves $256,721 in total interest over the life of the loan compared to 30 years.
