Property Taxes Explained: How They Affect Your Mortgage Payment

What Are Property Taxes?

Property taxes are recurring taxes charged by local governments on real estate. The revenue collected is typically used to fund public services such as schools, police departments, fire protection, road maintenance, parks, and other community programs. Unlike your mortgage payment, which repays money borrowed from a lender, property taxes are paid to local taxing authorities. If you have a mortgage, your lender often collects these taxes monthly through an escrow account and pays them on your behalf when they become due.

How Property Taxes Are Calculated

Property taxes are generally based on two factors: the assessed value of the property and the local tax rate. Although the calculation differs by jurisdiction, the basic principle remains the same—the higher the property value or tax rate, the more taxes you pay.

Why Property Taxes Matter When Buying a Home

Many buyers compare homes based only on purchase price or mortgage payment. However, property taxes can substantially affect the total monthly housing cost. Two homes with identical loan amounts may have very different monthly payments simply because one is located in an area with higher property taxes. Before purchasing a home, always estimate both the mortgage payment and annual property taxes together.

How Property Taxes Affect Your Monthly Mortgage Payment

Many mortgage lenders require borrowers to pay one-twelfth of the estimated annual property tax every month into an escrow account. The lender then pays the tax bill when it becomes due. This means your monthly mortgage payment often includes more than principal and interest. Property taxes, homeowners insurance, and sometimes mortgage insurance are added together to determine your total monthly payment.

Why Property Taxes Can Increase Over Time

Unlike fixed-rate mortgage payments, property taxes are not fixed. They may increase for several reasons, including rising home values, reassessments by local authorities, voter-approved tax increases, or changes in local government budgets. As a result, homeowners should expect that their total monthly housing costs may change even if their mortgage interest rate remains unchanged.

Understanding Escrow Accounts

An escrow account is a separate account managed by your lender to pay recurring property-related expenses. Rather than paying a large property tax bill once or twice a year, homeowners contribute smaller monthly amounts. This makes budgeting easier while ensuring taxes are paid on time. Each year, the lender reviews the escrow account and may adjust your monthly payment if taxes or insurance premiums have changed.

Ways to Reduce Property Tax Costs

Although homeowners cannot control local tax rates, there are several ways to manage property tax expenses.

Common Mistakes Homebuyers Make

One of the most common mistakes is assuming the mortgage payment shown in a loan estimate represents the full monthly housing cost. Buyers may overlook property taxes, insurance premiums, HOA fees, maintenance expenses, and utilities. Another mistake is comparing only home prices without considering differences in local tax rates. A less expensive home located in a high-tax area may actually cost more each month than a slightly more expensive property in a lower-tax area.

Use a Mortgage Calculator to Estimate Total Housing Costs

A mortgage calculator becomes much more useful when realistic property tax estimates are included. Entering estimated taxes, insurance, loan amount, interest rate, and repayment term provides a more complete picture of your expected monthly housing expenses. Running multiple scenarios also allows buyers to compare different neighborhoods, loan terms, and down payment amounts before making an offer on a property.
