When you’re preparing to protest your property taxes, the strength of your evidence shapes how your case is received. Maybe your neighbor’s nearly identical home was valued for less, or your house has repair issues the appraisal didn’t factor in. You can make a well-supported argument for a lower valuation with the right documentation.
At Texas Tax Protest, we help property owners gather and organize the records that carry real weight with appraisal districts. In this post, we’ll break down what types of evidence matter most so you know exactly what to collect and how it supports your protest.
Why Evidence Matters in Your Property Tax Protest
When challenging your property’s tax assessment, providing solid evidence is the cornerstone of a successful protest. Having the proper documentation and data can immensely influence the outcome, impacting the valuation the appraisal district assigns to your property.
Understanding Comparable Sales
Comparable sales, or “comps,” are recently sold properties that share key features with your home, such as location, square footage, and condition. They serve as a baseline to help you demonstrate why your assessed value may be too high.
For example, imagine your home in Texas is 1,800 square feet, and the appraisal district values it at $350,000. A nearby home with 1,600 square feet recently sold for $320,000. To account for the size difference, you can calculate a value adjustment. If homes in your Texas neighborhood cost $100 per square foot, the 200-square-foot difference would equal $20,000. That means the adjusted comp value would be $340,000, aligning closer to your assessed value.
Overall, presenting comps this way shows clear, quantifiable reasoning. The goal is to highlight market-based evidence using straightforward math, which helps strengthen your case during a property tax protest.
Gathering Detailed Property Information
In addition to comps, documents detailing your property’s specifics can bolster your argument. Photographs showcasing defects or necessary repairs are crucial, as they can highlight why your property might be valued too highly. Maintenance reports, professional appraisals, or repair estimates provide tangible evidence of your property’s condition.

Collecting Your Property’s Appraisal Records
When embarking on the journey to protest your property taxes, the first crucial step is gathering your property’s appraisal records. These documents are essential because they form the basis of your argument to the appraisal district, showing why your current valuation might be higher than it should be. Here’s how you can effectively assemble this vital evidence:
Obtain Your Appraisal District’s Data
To begin your property tax protest, find your county’s appraisal district and request your property’s appraisal report. This report includes key details like your assessed value, recent sales data, and comparable properties. Each Texas county has its own appraisal district, so if you live in Travis County, you can request this information through the Travis Central Appraisal District (TCAD). We recommend pulling this information early so you can review it thoroughly and compare it against relevant comps.
Evaluate Comparable Properties
Comparables are similar properties in your area that help you demonstrate your home’s value in the current market. When reviewing these, ensure they align closely with your property’s size, age, and location. Different differences like a swimming pool or a newly renovated kitchen can be adjusted. Mathematical adjustments matter because they provide a factual basis for why certain comps may be valued differently than your home, highlighting any discrepancies in your current valuation.
Document Property Conditions
Next, catalog any conditions of your property that might affect its market value. This can include structural issues, outdated interiors, or any necessary repairs. Taking quality photographs and keeping repair estimates or bills can provide solid evidence to illustrate the need for a reduced valuation.
Utilize Online Tools
Finally, leverage advanced technology tools that provide property data analysis and comparison. These can assist you in viewing potential disparities between your home and similar properties, empowering you with data needed for a compelling argument. At Texas Tax Protest, our commitment to blending cutting-edge technology with personal service ensures you have the most accurate and effective appraisal records at your disposal.
Gathering Comparable Property Sales Data
When you’re preparing to protest your property taxes in Texas, comparable property sales data is one of the most critical pieces of evidence. This entails selecting data from similar properties in your area that have recently sold at lower valuations than your property’s assessed value. Collecting this data can help demonstrate that your property’s appraisal is higher than it should be, giving you grounds for a successful protest.
To start, you’ll need to identify properties that are comparable to yours. Look for homes or commercial properties that match key criteria such as square footage, age, location, and lot size. Make sure that you include sales that have occurred within a reasonable timeframe, typically in the past year, as these will be the most relevant and impactful.
As you gather this data, make mathematical adjustments between the comps. Factors such as size differences, renovation statuses, or unique features should be adjusted to ensure you’re making an accurate comparison. This exercise can seem complex, but it’s essential for a fair representation of your property’s market value.
Documenting Property Condition Issues
Visible damage or needed repairs can affect your property’s market value – and that’s something the appraisal district should consider. Homes aren’t just made of square footage and nice yards – they have quirks, blemishes, and wear that can affect their market value.
Start by walking through your property and noting any problems. Structural concerns like roof leaks, foundation cracks, or outdated wiring should be documented clearly. Cosmetic issues matter, too. Peeling paint, worn-out flooring, or aging fixtures may not seem major, but they can still impact your appraised value when viewed alongside comps.
Take well-lit, detailed photographs that clearly show the condition of each area. For example, a photo of a cracked foundation or water-stained ceiling offers visual proof of issues that can lower your property’s valuation. These images help the appraisal district understand the real state of your home beyond square footage and location.
Alongside photos, gather any written estimates or reports from contractors or inspectors. These documents outline the cost of repairs and can be used to show how the condition affects your property’s worth.
Using Photographs to Support Your Case
Photographs are a powerful way to show the appraisal district what written documents may overlook. At Texas Tax Protest, we recommend using clear, well-lit images to support your protest. Here’s how photographs can strengthen your case:
- Document Property Condition: Capture visible issues like roof damage, cracks in the foundation, or outdated fixtures. These images reinforce repair estimates, and help show how your property’s condition affects its value.
- Compare to Other Properties: If a nearby home with similar features is appraised differently, photos can help support your comparison. Combine these visuals with square footage or condition adjustments to highlight inconsistencies.
- Highlight Core Features: Features like a blocked view, steep driveway, or limited yard space can affect market value. Photographs help present those details clearly so they aren’t overlooked during the review.
How to Adjust Comparables Mathematically for Accurate Valuations
When preparing to protest your property taxes, understanding how to adjust comparables mathematically is crucial for presenting a compelling case. Comparables, or “comps,” are similar properties in your neighborhood that help establish your property’s fair market value. Here’s how to ensure your comparables are adjusted accurately:
1. Analyze Property Size and Type
Start by comparing properties with similar square footage and type (e.g., single-family homes and condos). If your property size differs from the comp, adjust for this discrepancy. For instance, if your property is larger, it might command a higher value, so subtract it accordingly, and vice versa.
2. Account for Condition and Age
The condition and age of a property significantly impact its market value. If your home is older or needs repairs compared to a newer comp in pristine condition, adjustments should be made to lower your property’s estimated value. Equally, any improvements or upgrades on the comp should be factored in.
3. Location and Amenities Adjustments
Locality can make a critical difference. Adjust for any prime geographical benefits like proximity to schools or parks. If a comp benefits from better location amenities, consider decreasing your estimate. Additionally, amenities such as pools, garages, or extra bathrooms can require financial adjustment.
4. Use a Percentage Adjustment
Typically, adjustments are made based on percentage changes. If a comp recently sold for 10% less due to repairs needed, that percentage adjustment should be made to reflect similar conditions in your property, if applicable. This percentage is applied to the comp’s sales price to align with your property’s circumstances.
