Bexar County Property Tax Protest Evidence Tips
Strong evidence is the foundation of a successful Bexar County property tax protest. The Bexar Appraisal District (BCAD) evaluates over 700,000 properties in the San Antonio area, and mass appraisal methods can miss important details about your specific property.
This guide covers:
- Types of evidence BCAD accepts
- How to find and use comparable sales effectively
- Documenting condition issues with photos
- Building an unequal appraisal case
- How to organize and present your evidence
- Common evidence mistakes to avoid
Whether you're attending an informal review or an ARB hearing, the right evidence can mean the difference between a successful protest and a denied claim.
Types of Evidence BCAD Accepts
The Bexar Appraisal District accepts various forms of documentation to support your property tax protest. Understanding what qualifies as valid evidence helps you build a stronger case.
Market Value Evidence
Market value evidence demonstrates that your property's appraised value exceeds what a buyer would actually pay:
| Evidence Type | Description | Strength |
|---|---|---|
| Comparable sales | Recent sales of similar properties nearby | Very strong |
| Independent appraisal | Professional appraisal from licensed appraiser | Very strong |
| Listing data | Properties listed for sale in your area | Moderate |
| Purchase price | Your own recent purchase price | Strong (if within 2 years) |
| Closing documents | Settlement statement showing actual purchase | Strong |
Unequal Appraisal Evidence
Unequal appraisal evidence shows your property is assessed higher than comparable properties:
| Evidence Type | Description | Strength |
|---|---|---|
| Equity comparables | Similar properties assessed at lower values | Very strong |
| Price per square foot analysis | Comparison of assessed value per sq ft | Moderate |
| BCAD equity report | District's own comparable property data | Strong |
Property Condition Evidence
Condition evidence documents issues that affect your property's value:
| Evidence Type | Description | Strength |
|---|---|---|
| Photographs | Visual documentation of problems | Strong |
| Contractor estimates | Written repair cost estimates | Very strong |
| Engineering reports | Foundation, structural assessments | Very strong |
| Inspection reports | Home inspection findings | Moderate |
How to Find and Use Comparable Sales
Comparable sales are the most persuasive evidence for market value protests. BCAD determines property values based on sales of similar properties, so showing that comparable homes sold for less than your appraised value directly challenges their methodology.
What Makes a Good Comparable
The best comparables share these characteristics with your property:
- Location: Same neighborhood or zip code (78209, 78258, etc.)
- Size: Within 10-15% of your square footage
- Age: Built within 5-10 years of your home
- Features: Similar bedroom/bathroom count, garage, pool, etc.
- Sale date: Sold within 6-12 months before January 1 of the tax year
- Condition: Similar overall condition
Where to Find Comparable Sales Data
Several sources provide comparable sales information for San Antonio properties:
Free Resources:
- BCAD property search (bcad.org) - Shows assessed values
- Zillow, Realtor.com - Shows listing and sales prices
- Redfin - Provides recent sales data with details
Official Sources (More Reliable):
- Request BCAD's evidence package (check the red box on your protest form)
- MLS data through a real estate agent
- Bexar County Clerk records
Important Note: Under Texas law, appraisal districts don't have automatic access to sales prices. You may have information they don't.
How to Adjust Comparables
Raw sales prices rarely apply directly to your property. Adjustments account for differences:
Example Adjustment Calculation:
| Feature | Your Property | Comparable | Adjustment |
|---|---|---|---|
| Sale price | - | $385,000 | Base |
| Square footage | 2,200 | 2,400 | +$15,000 |
| Pool | No | Yes | +$20,000 |
| Condition | Average | Good | +$10,000 |
| Adjusted value | - | - | $430,000 |
If the comparable sold for $385,000 but would have sold for approximately $430,000 with your property's features, that comparable actually supports a value around $430,000 for your property.
BCAD appraisers use similar adjustment methods. Presenting your own adjusted comparables shows you understand the valuation process.
Documenting Condition Issues With Photos
BCAD uses mass appraisal, meaning appraisers don't inspect every property individually. Photos document conditions the district may not know about.
What to Photograph
Structural Issues:
- Foundation cracks (measure with a ruler for scale)
- Uneven floors or settling
- Wall cracks or separation
- Roof damage or missing shingles
Water Damage:
- Stains on ceilings or walls
- Warped flooring
- Mold or mildew
- Drainage problems in yard
Deferred Maintenance:
- Aging HVAC systems (photo of unit with date)
- Original windows in older homes
- Outdated electrical panels
- Worn plumbing fixtures
Functional Issues:
- Small or awkward room layouts
- Lack of storage
- Single-car garage in area of two-car garages
- No central air in homes where it's standard
Photo Best Practices
Follow these guidelines for effective photographic evidence:
- Date-stamp photos - Use camera settings or include a newspaper
- Show scale - Include a ruler, tape measure, or common object
- Capture context - Wide shots showing where damage is located
- Take multiple angles - Close-up and wide views of each issue
- Limit quantity - BCAD accepts a maximum of 10 photos online
Pairing Photos With Estimates
Photos become more persuasive when paired with professional estimates:
Photo of foundation crack + Contractor estimate for $15,000 repair = Strong evidence for value reduction
Contact licensed contractors for written estimates. Many provide free estimates, and the documentation significantly strengthens your case.
Building an Unequal Appraisal Case
Unequal appraisal is often overlooked but can be highly effective. This approach argues that your property is assessed higher than similar properties, regardless of actual market value.
Understanding the Legal Standard
Texas Property Tax Code Section 41.43 establishes the unequal appraisal standard. You must show that:
- Your property is appraised at a higher percentage of market value than comparable properties, or
- Your appraised value exceeds the median appraised value of comparable properties
Finding Unequal Appraisal Evidence
Step 1: Request BCAD's equity report
Check the box on your protest form requesting the district's evidence. BCAD will send you an equity report showing properties they compared to yours.
Step 2: Search for comparable properties
Use BCAD's online property search to find similar homes in your area. Look for properties with:
- Similar square footage
- Same number of bedrooms/bathrooms
- Comparable lot size
- Similar age and construction
Step 3: Calculate price per square foot
| Property | Assessed Value | Square Feet | $/Sq Ft |
|---|---|---|---|
| Your property | $425,000 | 2,200 | $193 |
| Comparable 1 | $380,000 | 2,250 | $169 |
| Comparable 2 | $395,000 | 2,300 | $172 |
| Comparable 3 | $360,000 | 2,100 | $171 |
| Median | - | - | $171 |
In this example, your property is assessed at $193/sq ft while similar properties average $171/sq ft. This difference supports an unequal appraisal claim.
Calculating Your Target Value
If the median assessed value per square foot is $171 and your home has 2,200 square feet:
$171 x 2,200 = $376,200 (target value based on unequal appraisal)
This approach can result in significant reductions even when market values are strong.
How to Organize and Present Your Evidence
Well-organized evidence improves your credibility with BCAD staff and ARB panels. A clear presentation helps decision-makers understand your case quickly.

- Focus on your strongest 2-3 points
- Be prepared to negotiate
- Know your minimum acceptable value
- Bring backup evidence in case they challenge your primary comparables

- Prepare a 5-10 minute presentation
- Speak to value, not taxes
- Be professional and concise
- Hearings may be limited to 15 minutes total
Common Evidence Mistakes to Avoid
Even strong cases can fail due to avoidable errors. Here are the most common mistakes Bexar County property owners make with evidence.
Mistake 1: Using Zillow Estimates Instead of Sales Data
Zillow "Zestimates" and similar online estimates are not evidence. ARB panels and BCAD staff require actual sales data or professional appraisals.
What to do instead: Use actual sale prices from closed transactions, verified through official sources or real estate agents.
Mistake 2: Selecting Poor Comparables
Choosing comparables that aren't truly similar weakens your case:
- Properties in significantly different neighborhoods
- Homes with major feature differences (3 bed vs. 5 bed)
- Sales from more than 12 months before January 1
- Foreclosures or distressed sales without acknowledging the discount
What to do instead: Select 3-5 comparables that genuinely match your property's characteristics. Quality matters more than quantity.
Mistake 3: Talking About Taxes Instead of Value
BCAD and the ARB set property values, not tax rates. Arguing that your taxes are too high misses the point.
What to do instead: Focus exclusively on why your property's market value or assessed value should be lower. The tax impact follows automatically from a lower value.
Mistake 4: Ignoring Property Record Errors
Many property owners don't verify that BCAD's records are accurate. Common errors include:
- Incorrect square footage
- Wrong number of bathrooms
- Nonexistent features (pool, extra garage)
- Outdated condition ratings
What to do instead: Review your property record on bcad.org before filing. Correct errors as part of your protest.
Mistake 5: Submitting Evidence Late
Evidence submitted after BCAD's deadlines may not be reviewed before your informal meeting, reducing your chances of settlement.
What to do instead: Upload evidence within 7 days of receiving your protest confirmation. Earlier submission gives appraisers time to review before your meeting.
Mistake 6: Failing to Request BCAD's Evidence
Texas law requires BCAD to provide their evidence at least 14 days before your hearing. This "HB 201 package" shows exactly what they'll present.
What to do instead: Check the red box on your protest form requesting the district's evidence. Review their comparables and prepare counter-arguments.
Mistake 7: Using Last Year's Value as Evidence
Arguing that your value increased too much from last year is not persuasive. What matters is whether the current year's value is accurate.
What to do instead: Focus on current market conditions, comparable sales, and equity analysis for the tax year in question.
