Property taxes can change the real monthly payment
Property taxes are one of the biggest reasons a mortgage estimate can differ from the payment a homeowner actually carries. They are usually local charges based on assessed value, tax rates, and local rules. For many buyers, taxes are collected monthly through escrow even though the bill is annual or semiannual.
Understanding property taxes helps buyers compare homes in different neighborhoods, avoid underestimating monthly cost, and prepare for payment changes after purchase.

How property taxes are estimated
A simple planning estimate multiplies the home value by an annual property tax rate. Real tax bills can be more complex because local governments may use assessed value, exemptions, millage rates, reassessment schedules, and special assessments.
Buyers should not assume the seller's current tax bill will remain unchanged. A purchase price, reassessment, loss of an exemption, or local rate change can affect the future bill.
Worked example: tax rate and monthly payment
Assume a home price of $420,000 and a 1.25% annual property tax estimate.
| Item | Calculation | Estimate |
|---|---|---|
| Annual property tax | $420,000 x 1.25% | $5,250 |
| Monthly tax estimate | $5,250 / 12 | $437.50 |
| Payment impact | Added to PITI estimate | About $438/month |
This estimate should be replaced with local tax data before making a final budget decision.
Common Misconception
The seller's tax bill may reflect older assessed value, exemptions, or local rules. Buyers should ask how taxes may be reassessed after purchase.
How property taxes connect to escrow
When a loan uses escrow, the servicer estimates annual property taxes, collects a monthly amount, and pays the tax bill when due. If the estimate is too low, the borrower may see an escrow shortage and a higher future payment.
That is why property taxes belong in every affordability estimate, not only in closing documents.
