Amortization Schedule
PITI Explained
Principal + Interest + Taxes + Insurance. This is your true monthly housing cost, not just the loan payment.
PMI Rules
Private Mortgage Insurance is required when LTV > 80%. Typically 0.3–1.5% of loan balance annually. Drops when you reach 20% equity.
DTI Ratios
Front-end: housing costs ÷ income (max 28%). Back-end: all debts ÷ income (max 36–43% for conventional).
