What income do I need for a $400K mortgage?
Using the standard 36% DTI guideline, a $400,000 home with 20% down ($80,000 down, $320,000 loan) at 6.82% has a P&I payment of approximately $2,090/month. With taxes and insurance adding ~$533/month, your total housing cost is about $2,624/month. To keep housing below 28% of gross income, you'd need approximately $112,447/year in gross income.
How much is the down payment on a $400K home?
Down payment options on a $400,000 home: 3% = $12,000, 5% = $20,000, 10% = $40,000, 20% = $80,000. A 20% down payment ($80,000) eliminates PMI. FHA requires 3.5% minimum ($14,000). Remember to budget closing costs on top of the down payment — typically 2–5% of the loan amount.
