The Property Tax Cost Home Buyers Often Miss

Buyers often compare homes by price and principal-and-interest payment. Property tax can materially change that comparison. A $400,000 home taxed at 1% adds about $333 per month; at 2%, it adds about $667 per month before insurance, HOA dues, or maintenance.

The tax bill is a cost of ownership, not a lender fee. Paying it through escrow makes the expense monthly, but does not make it smaller.

Tax rates, assessed values, exemptions, special assessments, and local taxing districts all matter. A current owner may also benefit from an exemption or assessment cap that will not transfer to the buyer. After a sale, the property may be reassessed using a higher value.

A listing's monthly estimate can be based on the seller's current bill. That number may not represent what the next owner will owe.

Look up the parcel on the county or municipal tax-assessor website and review the latest bill. Ask how and when reassessment occurs, whether any special district charges apply, and which exemptions are included in the current amount.

With a fixed-rate mortgage, principal and interest generally stay stable, but the escrow portion can change when taxes or insurance change. A servicer's annual escrow analysis may increase the monthly collection and may also recover a prior shortage.

Use a property-specific tax estimate whenever possible and leave room for reassessment. The safer comparison is total monthly cost, not the mortgage payment shown in a listing widget.
