How to Use Your County's Property Search Tool to Check Your Appraisal

How to Use Your County's Property Search Tool

Every Texas county appraisal district maintains a free online property search tool that shows appraised values, property details, exemptions, and taxing entities for every property in the county. This tool is one of the most useful resources available to Texas homeowners - and most people do not know it exists.

You can use it to check your own appraised value, verify that your property records are accurate, or find comparable properties for a tax protest.

The 60-Second Summary

• Every Texas county has a free property search tool on its appraisal district website - no account, no fee
• Three things to look up: your appraised value, your property record (sqft, beds/baths, year built, features), and comparable properties near you
• Check the record for errors first - 100+ sqft of phantom living area can add $15,000-$30,000 to your appraised value
• Two kinds of comparables: recent sales below your value (market argument) and similar homes appraised lower per sqft (unequal appraisal argument)
• All data is public record - you can see what your neighbors are appraised at, which is exactly what the unequal-appraisal argument uses

How to Find Your County's Property Search Tool

Visit your county appraisal district's website. The property search tool is typically on the homepage or under a "Property Search" or "Search" link.

Here are the appraisal district websites for the 18 counties we serve:

Searching for Your Property

Most county search tools offer several ways to find a property:

Search by Address

Enter your street number and street name. You usually do not need to include the city or zip code. This is the quickest way to find your own property.

Search by Owner Name

Enter the property owner's last name. This returns all properties in the county owned by that person. Useful if you own multiple properties or want to look up a specific owner.

Search by Property ID

Enter the property ID number (also called account number or PID). This is the most precise search and returns a single property. Your property ID is printed on your Notice of Appraised Value and your tax bill.

Search by Map

Some counties offer an interactive map where you can click on a property to view its details. This is useful for browsing properties in a specific neighborhood or subdivision.

Understanding Your Property Detail Page

Once you find your property, the detail page shows several sections of information. Here is what to look for and what each section means.

Appraised Value vs. Assessed Value

These are two different numbers, and the difference matters:

• Appraised value (also called market value) - What the appraisal district says your property is worth on the open market as of January 1
• Assessed value (also called capped value) - The value used to calculate your tax bill, which may be lower than the appraised value if you have a homestead exemption with the 10% cap in effect

If your assessed value is lower than your appraised value, the 10% cap is saving you money. The gap between the two numbers is your "HS Cap Loss" - the amount of value that is shielded from taxation.

For a deeper explanation, see our guide on appraised value vs. fair market value.

Property Characteristics

This section lists the physical details the appraisal district has on file for your property:

• Square footage (living area)
• Lot size (land area)
• Year built
• Number of bedrooms and bathrooms
• Number of stories
• Exterior wall type (brick, siding, etc.)
• Roof type
• Garage type and size
• Pool (if applicable)
• Condition rating (some counties display this)
• Quality/class rating (e.g., "Average," "Good," "Excellent")

Check every field. Errors in this section directly inflate your appraised value. If the district has your home listed at 2,400 square feet but it is actually 2,200 square feet, that 200-square-foot error could add $20,000-$40,000 to your appraised value.

Exemptions

This section shows which exemptions are currently applied to your property:

• HS - General homestead exemption
• OV65 - Over 65 exemption
• DP - Disabled person exemption
• DV - Disabled veteran exemption

If you have filed for a homestead exemption but do not see it listed here, contact your appraisal district. A missing exemption means you are paying more than you should.

Taxing Entities and Rates

This section lists every government entity that taxes your property and their individual tax rates:

• County
• School district
• City (if inside city limits)
• Hospital district
• Community college district
• MUD, PID, or other special districts

Add up all the rates to get your total combined tax rate. This is the rate applied to your taxable value to calculate your annual tax bill.

Value History

Most counties show several years of appraised values, letting you see how your value has changed over time. This is useful for understanding trends and identifying years where the value jumped significantly.

Sales History

Some counties display the property's sales history, including sale dates and sale prices (when available). Since Texas is a non-disclosure state, sale prices are not always recorded - but when they are, this data is valuable for protests.

How to Check for Errors in Your Property Record

Errors in your property record happen regularly. Appraisal districts manage hundreds of thousands of properties, and data entry mistakes happen. Here is a systematic approach to checking your record.

Step 1: Verify Square Footage

Compare the living area square footage on the appraisal district record to your home's actual size. Sources for your actual square footage:

• Your home's original building plans or blueprints
• The appraisal from when you purchased the home
• Your home inspection report
• A professional measurement (if you suspect a significant error)

A difference of 100+ square feet is worth pursuing. At $150-$200 per square foot in appraised value, even a small error adds up.

Step 2: Check Bedroom and Bathroom Count

An extra bedroom or bathroom on your record adds value even though it does not exist. Count the actual rooms in your home and compare to the record.

Step 3: Verify Lot Size

Check that the lot size matches your survey or deed. Lot size errors are less common but can significantly affect value, especially in areas where land is expensive.

Step 4: Confirm Year Built

A wrong year built changes the depreciation calculation. If your home was built in 1995 but the record says 2005, the district is applying less depreciation than it should.

Step 5: Check for Features You Do Not Have

Look for amenities listed that do not exist:

• Pool listed but you do not have one
• Garage listed as attached when it is a carport
• Second story listed for a single-story home
• Fireplace count is wrong

Step 6: Assess the Condition Rating

If your county displays a condition rating, check whether it reflects reality. A home rated "Good" that actually has deferred maintenance, foundation issues, or an aging roof is being overvalued.

What to Do If You Find Errors

File a property tax protest and present documentation of the correct information. Bring:

• Photos showing the actual condition or layout
• Your home's building plans or inspection report
• A survey showing the correct lot size
• Any other documentation that proves the error

Correcting an error is one of the strongest grounds for a protest because the evidence is objective and verifiable. For more on building a protest case, see our comparable properties guide.

How to Find Comparable Properties for a Protest

The property search tool is also your best free resource for finding comparable properties to support a tax protest. There are two types of comparables you can look for.

Comparable Sales (Market Value Argument)

Search for properties in your area that recently sold for less than your appraised value. The best comparable sales are properties that:

• Are in the same neighborhood or subdivision
• Sold within the last 6-12 months
• Have similar square footage (within 10-15% of yours)
• Have a similar year built, bedroom/bathroom count, and condition
• Sold at arm's length (not foreclosures, family sales, or distressed sales)

Not all counties display sale prices in their search tool (Texas is a non-disclosure state). If your county does not show sales data, you can supplement with data from real estate websites like HAR.com, Zillow's "Recently Sold" filter, or Redfin.

Comparable Appraisals (Unequal Appraisal Argument)

Search for properties similar to yours and compare their appraised values on a per-square-foot basis. If your home is appraised at $175 per square foot but comparable homes in your area are appraised at $155 per square foot, you have a strong unequal appraisal argument.

To find unequal appraisal comparables:

1. Search by subdivision or neighborhood - Most search tools let you filter by subdivision name
2. Filter for similar properties - Look for homes with similar square footage, year built, and bedroom/bathroom count
3. Calculate value per square foot - Divide the appraised value by the living area square footage for each property
4. Identify properties appraised lower - These are your comparables for an unequal appraisal argument
5. Select 5-10 strong comps - The more comps you have, the stronger your case

Tips for Effective Searching

• Start narrow and expand - Begin with your immediate subdivision, then expand to surrounding neighborhoods if you need more comps
• Use the map view if available - It helps you visualize which properties are truly nearby
• Record the property IDs of your comps so you can reference them at the hearing
• Print or screenshot the property detail pages for your evidence packet
• Note differences between your property and each comp (size, age, condition, amenities) so you can address them at the hearing

Beyond the Search Tool: Other Free Resources

The county property search tool is the starting point, but other free resources can supplement your research:

• Your tax bill - Breaks down the exact amount owed to each taxing entity
• Your Notice of Appraised Value - Shows the appraisal district's value and includes filing instructions
• Real estate websites (HAR.com, Zillow, Redfin) - Show recent sale prices, which county tools may not include
• Google Maps/Street View - Useful for viewing comparable properties from the outside to assess condition

Protest in Your County

Once you have pulled your record and identified comparables, the next step is filing the protest. Each appraisal district handles filing, evidence submission, and informal review slightly differently. See our county guides for local detail:

• Harris County
• Dallas County
• Tarrant County
• Bexar County
• Travis County
• Collin County
• See all counties we serve

Use What You Find

The data in your county's property search tool is the foundation of a strong property tax protest. Check your records for errors, compare your value to similar properties, and file a protest if the numbers do not add up.

At Ballard Property Tax Protest, we analyze property data across all 18 Texas counties we serve to build the strongest possible case for a reduction. You only pay if we save you money.

The protest deadline is May 15 or 30 days after your Notice of Appraised Value, whichever is later.
