💰 Budgeting for Your $400K Home

A 15-year mortgage on a $400k home requires approximately $500/month more than a 30-year ($2,524 vs. $2,022), but you'll save over $273,000 in interest. This option works best if you: (1) Have stable, high income ($110,000+), (2) Low other debts, (3) Already have emergency savings, (4) Are max-funding retirement accounts. Don't stretch to afford a 15-year if it leaves you cash-poor—financial flexibility matters.

📈 Market Insights: $400K Home Price Point

Only about 10-15% of homebuyers choose 15-year mortgages, but those who do build wealth significantly faster. 15-year mortgages typically offer 0.5-0.75% lower interest rates than 30-year options due to lower lender risk. This strategy is popular with buyers age 40-50 who want to own their home before retirement, high-income professionals, and financially conservative buyers who dislike debt. In 2025's interest rate environment, the rate advantage and interest savings make 15-year mortgages especially attractive for those who can afford the payment.

✅ Affordability & Qualification Guide

To qualify comfortably for a $400k 15-year mortgage: (1) Income of $105,000-$120,000 minimum, (2) Excellent credit (740+) for best rates, (3) Low debt-to-income ratio (under 35% ideal), (4) $80,000 down payment (20%), (5) Strong cash reserves (6+ months), (6) Job stability and career growth trajectory. Lenders qualify you the same as 30-year, but you should self-qualify more conservatively since the payment is higher and leaves less monthly flexibility.

💡 Pro Tip

Use the 28/36 rule: Housing costs should be ≤28% of gross income, and total debt payments ≤36%. For this $400K home scenario, aim for these benchmarks to ensure comfortable affordability.
