Quick answer: Estimate property tax as part of the true monthly mortgage cost.

What this means

Property taxes vary by location and assessed value, so buyers should verify local estimates before making an offer.

Monthly escrow estimates can change after reassessment or tax changes.

Key takeaways

  • Use the all-in monthly cost, not only principal and interest.
  • Check leftover cash after debts and living expenses.
  • Verify lender, tax, insurance, and HOA numbers before purchase.

Formula or planning rule

True monthly cost = P&I + taxes + insurance + PMI + HOA + utilities + maintenance reserve

Common mistakes

  • Ignoring utility increases after moving.
  • Using lender approval as the same thing as comfort.
  • Spending cash-to-close without preserving reserves.
  • Forgetting HOA, PMI, or reassessment risk.
