⚠️ PMI Required. Your down payment is 14.7% of the purchase price, below the 20% threshold. Estimated PMI: $310/month (~0.8% annually). PMI is eliminated once you reach 20% equity.
⚠️ Emergency Fund Warning. Purchasing at this price leaves you with $0 after closing, below your $18,000 emergency fund goal. Homeownership generates unexpected expenses; depleting your emergency fund to buy is a significant risk.
Affordability Scenarios
| Scenario | Max Price | Required Down | Monthly Payment | Note |
|---|---|---|---|---|
| Your DTI limits | $544,802 | $80,000 | $4,036/mo | front-end DTI |
| Conservative (20% down) | $400,000 | $80,000 | — | Down payment sufficient |
Lenders approve based on gross income and DTI ratios, but your take-home determines whether you can actually afford the payments. Always run both calculations. The conventional 28/36 rule is a ceiling, not a target.
