Principal & Interest (P&I)

P&I is the base mortgage payment computed from the loan amount, term, and rate. It excludes taxes and insurance.

Property taxes

Often 0.5โ€“2% of home value per year depending on locality. Divide yearly tax by 12 to estimate monthly impact.

Homeownerโ€™s insurance

Annual premium divided by 12. Rates vary by location and coverage.

PMI

Private Mortgage Insurance applies when down payment < 20%. It can often be removed around 20% equity.

Checklist

  • Estimate taxes and insurance locally
  • Consider PMI thresholds
  • Stress-test rate +0.5%
