How Do Property Taxes Affect Mortgage Payments?

Property tax does not change your principal and interest. It changes the draft that leaves your bank account if the lender escrows it. Most first-time conventional, FHA, and VA loans escrow taxes and insurance. That is why a New Jersey listing and a Tennessee listing with the same price are not the same payment.

The monthly translation

Annual tax ÷ 12 = the escrow line. On a $350,000 home, 0.6% tax is $175/month. 1.2% is $350. 2.2% is $642. That 1.6-point gap is $467 a month — more than a 1% interest-rate change on a typical first-time loan.

Assessed value is not always purchase price. Some states cap assessment growth; others reassess at sale. Use the county estimate or last year’s bill on a resale, not a national average, when you are close to a decision. Our calculator’s tax field is a percent of the price you type — a planning shortcut.

How lenders treat it

Underwriters include the monthly tax in the housing ratio. A high-tax town can deny a file that would approve in a low-tax town at the same price. That is not the calculator being “wrong.” It is DTI.

Escrow shortages after a tax increase raise the payment even if your rate is fixed. Your P&I is fixed on a fixed-rate loan. Your PITI is not.

Worked example

$350,000, 20% down, 6.5% 30-year. P&I ≈ $1,770. Insurance 0.35% ≈ $102. At 0.7% tax, PITI ≈ $2,076. At 1.8% tax, PITI ≈ $2,397. Same loan, $321 more per month. Open the taxes and insurance calculator and change only the tax rate to see it.
