Common Down Payment Amounts
计算示例
$350,000 home with 20% down, $30,000 saved, saving $1,000/month.
- 01Down payment = $350,000 × 20% = $70,000
- 02Still need = $70,000 - $30,000 = $40,000
- 03Months to save = $40,000 / $1,000 = 40 months
- 04Loan amount = $350,000 - $70,000 = $280,000
常见问题
Do I need 20% down?
No, many loans require as little as 3-5% down. However, putting less than 20% down typically requires PMI, adding $50-200/month.
