Tax assessment

The county's official valuation of the property for tax purposes. Doesn't always match market value. Owners can usually appeal if they think it's too high.

Why a seller cares

The assessment is the county's valuation for taxes, and it can be appealed if it is too high. It has almost nothing to do with your sale price, and buyers sometimes read it as if it did.

Part 2 of 4

A simple example

Your assessment is $310,000 and the home is worth about $290,000. You appeal, and the county lowers it, which lowers the bill the buyer inherits.

Tax assessment: a simple example
The situationWhat tends to follow
Assessment above market valueAn appeal, and a lower bill for you and the buyer
Assessment well below marketA lower bill now, and in some states a reset when it sells
A buyer treating the assessment as the valueA conversation about what the number is for

The assessment is a tax figure with an appeal process. It is not the appraisal.

What people get wrong

That a high assessment supports a high price. Appraisers ignore it, and so do buyers' agents.
