Key Considerations
- Your monthly P&I on a $320,000 loan at 6.5% for 30 years comes to approximately $2,023 -- the 28% rule suggests you need a household gross income of at least $7,225 per month ($86,700 annually).
- Over 30 years at 6.5%, you will pay roughly $408,000 in total interest on top of the $320,000 principal -- nearly doubling the total cost of the home.
- Opting for a 15-year term raises the monthly payment to about $2,789 but cuts total interest to approximately $182,000, a savings of over $226,000.
- At this price you should budget $8,000-$16,000 for closing costs, plus $1,500-$3,500 for a home inspection and appraisal.
- Consider rate buydown points: paying 1% of the loan ($3,200) upfront typically reduces your rate by 0.25%, saving about $55 per month and paying for itself in under 5 years.

Frequently Asked Questions
- What kind of home does $400,000 buy in move-up markets?
- In cities like Denver, Nashville, Portland, and Atlanta suburbs, $400,000 typically gets you a four-bedroom single-family home built within the last 20 years. You can expect 2,000 to 2,500 square feet, a two-car garage, and access to well-rated public schools. In high-cost metros, this price may only reach a three-bedroom townhouse or a home requiring significant updates.
- How do school district ratings affect a $400,000 purchase?
- Homes zoned to top-rated school districts in the $400,000 range often command a 10% to 20% premium over similar homes in adjacent districts. A $400,000 home in a highly rated district may offer 300 to 500 fewer square feet than a comparable property in a lower-rated zone. Research GreatSchools ratings and visit schools in person before prioritizing district boundaries in your search.
- When does refinancing make sense on a $400,000 mortgage?
- Refinancing a $320,000 balance typically pays off when you can reduce your rate by at least 0.75% and plan to stay in the home for three or more years. Dropping from 6.5% to 5.5% saves about $206 per month and roughly $74,000 over the remaining loan term. Factor in closing costs of $8,000 to $12,000 at this loan size when calculating your break-even timeline.
- Is a 15-year mortgage worth the higher payment at $400,000?
- A 15-year term on the $320,000 balance at 5.9% costs about $2,683 per month, roughly $660 more than the 30-year option. That higher payment requires income near $115,000 under the 28% rule but saves over $245,000 in total interest. It suits buyers with strong cash flow who want to be mortgage-free before retirement.
