PATRICK'S QUICK ANSWER

You need three kinds of evidence to protest successfully: recent comparable sales from the last three to six months, photos that document condition issues, and contractor or appraisal estimates that put a dollar figure on needed repairs. The deciding factor is that each piece shows BCAD's value is above what your home is really worth. A recent appraisal carries the most weight. Gather the evidence before you file, and present it in one organized packet. Ask Patrick to check your home's value.

To protest your property taxes in San Antonio, you need evidence showing your home is worth less than the assessed value. The three strongest types of evidence are comparable sales (comps), photographs documenting condition issues, and contractor or appraisal estimates. The more objective data you have, the stronger your case before the Bexar County Appraisal District (BCAD).

Comparable Sales (Comps)

The most persuasive evidence is recent sales of similar homes in your neighborhood. You want homes that sold within the last 3 to 6 months, within a half-mile to one mile of your property, and with similar square footage, bedrooms, bathrooms, and lot size. Sales prices should be lower than your assessed value to justify a reduction. You can find comps through the BCAD website, your real estate agent, or public tax records.

The meaning: comps are the market's own opinion of value, and the board is used to weighing them first.

The money consequence: sales below your assessed value are direct evidence the number is too high, and three to five of them build the case.

The real-world play: pull the sales yourself or ask an agent for a market analysis. The data is public, and the strongest comps are the most recent and most similar.

Photographs of Your Property

Photos showing deferred maintenance, needed repairs, interior wear and tear, or exterior defects help support a lower value. Document cracked foundations, outdated kitchens, worn flooring, roof damage, plumbing issues, and any safety or functional problems. Take clear photos with good lighting and date-stamp them if possible. The appraisal district uses photos too, so your own evidence can correct the record if theirs is inaccurate.

The meaning: photos show the condition the district's mass appraisal never saw, correcting the record with reality.

The money consequence: a documented defect is a dollar adjustment, and photos make the adjustment easy for the panel to grant.

The real-world play: shoot wide and close, date-stamp if you can, and caption each photo so the panel knows exactly what they are looking at.

Appraisals and Contractor Estimates

A recent appraisal from a qualified appraiser is powerful evidence, especially if you purchased or refinanced within the past year. Contractor estimates for needed repairs also carry weight because they quantify the cost to cure defects. Estimates for a new roof, foundation repair, HVAC replacement, or kitchen remodel give the appraisal review board a dollar figure to deduct from the assessed value.

The meaning: a formal appraisal is the strongest single document you can bring, because it is an independent professional opinion of value.

The money consequence: an appraisal from a recent purchase or refinance can settle the argument outright, while estimates convert repairs into a deduction.

The real-world play: if you bought or refinanced in the last year, bring that appraisal. It is worth more than a dozen comps in most hearings.

How to Present Your Evidence

Organize your evidence in a clear folder or binder. Label each piece and summarize your requested value reduction on the first page. If you have multiple comps, highlight the sales price and the key features that make each home comparable to yours. For photos, group them by issue and add a short caption. For estimates, show the total repair cost and explain how it affects the value of your home.

The meaning: the panel has limited time, so the packet does the persuading before you say a word.

The money consequence: a clear summary page with a requested value gives the panel an easy yes, while a scattered packet invites a no.

The real-world play: one binder, one summary page, labeled sections. That is the presentation style that wins, Patriot Nation.

Patrick's Take

The quality of your evidence is everything in a tax protest. I tell homeowners to pull at least three comparable sales from the last six months and photograph any condition issues before the appraiser comes out. You want a clear story about why your home is worth less than what BCAD says.
