How Texas Counties Calculate Property Values

Every year, county appraisal districts across Texas assess the market value of all taxable property within their jurisdiction. These assessments form the basis of your property tax bill. Understanding how counties arrive at your property's value can help you determine whether your assessment is fair and whether a protest may be warranted.

The Three Appraisal Approaches

Texas appraisal districts primarily use three methods to determine property value:

1. Sales Comparison Approach

This is the most common method for residential properties. The district looks at recent sales of comparable properties in your area and adjusts for differences in size, condition, features, and location to estimate your property's market value.

2. Income Capitalization Approach

Used primarily for commercial and income-producing properties, this method estimates value based on the property's ability to generate income. The district analyzes net operating income and applies a capitalization rate to determine value.

3. Cost Approach

This method estimates the cost to replace the property, minus depreciation, plus the value of the land. It is most useful for newer construction or special-purpose properties that do not frequently sell on the open market.

Factors That Influence Your Assessment

Several factors can influence how the appraisal district values your property, including recent sales activity in your neighborhood, changes to the property (additions, renovations, or damage), local market trends, and the accuracy of the district's property records.

Errors in the district's data, such as incorrect square footage, wrong property classification, or outdated condition ratings, can lead to inflated assessments. A professional review can identify these discrepancies and build a case for correction.
