If you’ve ever tried to look up what a home in Alamo Heights or Stone Oak actually sold for and hit a wall, you’re not imagining things — Texas law keeps those numbers private. Understanding why Texas is a non-disclosure state, and how buyers, sellers, and agents navigate that reality, can mean the difference between pricing your home right and leaving money on the table. In this post, I’ll walk you through exactly what non-disclosure means, how the comps process actually works here in San Antonio, and why having the right agent matters more in Texas than almost anywhere else in the country.
Quick Facts: Texas Non-Disclosure State
| Texas Disclosure Law | Sellers are NOT required to report sale prices to public records |
| Non-Disclosure States | Texas is one of ~12 states with non-disclosure laws |
| Zillow / Redfin Accuracy | Zestimates in TX are often off by 5–15% due to missing sale data |

What “Non-Disclosure State” Actually Means
In most states, when a home sells, the final sale price becomes part of the public record — stamped into county deed filings and freely searchable by anyone. Texas takes a fundamentally different approach. Here, sellers are under no legal obligation to report the actual sale price to any public government body when a deed is recorded.
That means the Bexar County Appraisal District (BCAD), journalists, curious neighbors, and yes — websites like Zillow and Redfin — don’t automatically receive confirmed sale prices. They can make educated guesses, but those guesses are often built on incomplete or outdated information.
It’s a bit like trying to understand the health of a garden by only looking at it from across the street. You might get a general impression, but you’d miss the struggling root system underneath. Non-disclosure creates a genuine information gap — and knowing that gap exists is the first step toward working around it smartly.
Which Transaction Details Are Still Public?
When a home sells in Texas, the deed transfer itself is recorded publicly — so you can confirm that a property changed hands, when it happened, and who the new owner is. What’s missing is the dollar amount attached to that transaction.
County appraisal districts like BCAD do receive sales data voluntarily or through the Texas Comptroller’s Property Value Study process, but participation and accuracy vary. The appraisal district uses this data primarily to set assessed values for property tax purposes, not as a consumer-facing price registry.
Why Zillow and Redfin Can’t Show You Exact Sold Prices in Texas
This is the question I hear constantly from buyers shopping neighborhoods like Helotes, Boerne ISD pockets near I-10, or the newer master-planned communities along Highway 281 north of the 1604 loop. They pull up Zillow, see a “Zestimate,” and assume it’s grounded in solid recent sales data. It often isn’t — not in Texas.
Zillow’s algorithm relies heavily on publicly reported sale prices to calibrate its estimates. When that data doesn’t exist — or only trickles in through voluntary reporting and tax assessments — the model fills gaps with older sales, tax-assessed values, and regional averages. In a dynamic market like San Antonio, where prices in areas like Converse near Judson ISD or the Medical Center corridor can shift meaningfully in six months, that lag creates real distortion.
Redfin and Realtor.com face the same constraint. They’re not withholding information out of spite — they simply don’t have it. Some listings show “MLS-reported” sold prices, but those figures come from data agents voluntarily enter into the MLS, not from a government mandate. The picture is patchwork at best.
What About the Zestimate Accuracy Problem?
Zillow’s own published accuracy data shows their Zestimates carry a median error rate of around 2–3% nationwide — but that number rises significantly in non-disclosure states like Texas. In fast-moving San Antonio submarkets, I’ve personally seen Zestimates that were $30,000–$50,000 off on homes in the $300,000–$450,000 range.
For buyers, that means you could be making an offer based on a value that’s substantially wrong. For sellers, it could mean underpricing a home in a neighborhood like Alamo Ranch or Shavano Park where recent sales justify a stronger ask. Either way, the stakes are real.
How Buyers and Agents Actually Find Comparable Sales (Comps) in Texas
Here’s the good news: the data exists — it’s just not publicly free. The San Antonio Board of Realtors (SABOR) MLS is the single most reliable source for actual sold prices in our market. When an agent lists a home on the MLS and it closes, the closing price is entered into that system. Only licensed agents with active MLS subscriptions can access it.
When I sit down to pull comps for a client — whether they’re looking at a 1970s ranch in Kirby, a newer build in Cibolo within the Schertz-Cibolo-Universal City ISD, or a mid-century updated home in Olmos Park — I’m pulling from that MLS database. I’m looking at sales from the last 90 to 180 days, filtering by square footage, lot size, condition, school district, and proximity. It’s methodical work, like preparing soil before planting — the foundation has to be right before anything else grows.
Appraisers use the same MLS data, which is why your lender’s appraisal often tells a more accurate story than any automated online estimate. If you’re getting a conventional loan through a local lender like Frost Bank or USAA’s real estate mortgage division here in San Antonio, the appraiser they hire is pulling from the same reliable source your agent should be using.
Other Tools Agents Use to Cross-Check Values
Beyond the MLS, experienced agents also pull data from BCAD’s property search tool, which shows assessed values and can flag recent deed transfers — even without prices. We cross-reference with county tax records, prior listing history, and sometimes neighborhood HOA sales reports in communities like The Dominion or Sonterra where resale activity is tracked closely.
Some agents also use platforms like RPR (Realtors Property Resource), a NAR-affiliated tool that aggregates MLS data, tax records, and distressed property information into a single dashboard. It’s not perfect, but it adds another layer of validation when pricing in less active zip codes like parts of 78207 or 78211 on San Antonio’s west and south sides where comparable sales can be sparse.

Why Non-Disclosure Matters When You’re Pricing a Home to Sell
Pricing a home in Texas isn’t just an art — it’s a discipline that requires access to information most homeowners simply don’t have. When sellers try to price their home using Zillow or by looking at what their neighbor “thinks” their house sold for, they’re often working with incomplete data. Overpricing a home in a market like Northeast San Antonio along the 35 corridor — where buyers are commuting to Fort Sam Houston or Randolph AFB — can mean sitting on the market long enough to raise red flags.
Days on market matters enormously here. A home that sits for 45 days in a neighborhood like Windcrest or Universal City starts generating questions: Is something wrong with it? Why won’t it sell? Buyers begin assuming negotiating power that the seller never intended to give. The right price from day one keeps momentum, generates multiple offer scenarios, and protects net proceeds.
That’s why the Comparative Market Analysis (CMA) your agent prepares before listing is arguably the most valuable document in the entire transaction. A properly researched CMA built from real MLS sold data — not Zillow’s best guess — is the seed from which the entire selling strategy grows. Get it right, and everything else has a much better chance of thriving.
Seller-Side Risks of Relying on Online Estimates
I’ve seen sellers in neighborhoods like Stone Oak and Encino Rio leave significant money behind because they anchored to a Zestimate that was lower than the market actually supported. Conversely, sellers in slower-moving areas like parts of far Southwest San Antonio near Lackland AFB have overpriced based on inflated online estimates and endured extended market times that ultimately required price reductions.
The Texas non-disclosure environment makes both of these mistakes more likely without professional MLS access. It’s not a criticism of homeowners — it’s just the reality of the information asymmetry the law creates. Working with an agent who does rigorous comp work is the most direct way to close that gap.
What This Means for Buyers Competing in a San Antonio Neighborhood
For buyers, non-disclosure creates a different kind of challenge. When you’re competing for a home in a sought-after school district — say, Northside ISD pockets near Helotes, or Northeast ISD near TPC Parkway — you may not have a clear intuition for where to set your offer. You know the list price, but you don’t know if homes in that neighborhood have been selling at, above, or below asking.
Your agent’s MLS access becomes your competitive advantage. Knowing that homes in a particular zip code have been closing an average of 2% above list price over the past 60 days tells you something critically important about where to anchor your offer. Knowing that a specific street has had two sales in the last year — both below asking — tells you something equally important in the opposite direction.
Buyers using VA loans (common in San Antonio given our five military installations) also need to be especially thoughtful here. VA appraisals are known for being strict, and if an agent helps you bid significantly over list price without solid comp support, a low appraisal can derail the entire transaction. Real sold data from the MLS protects you from that scenario.
How Texas Non-Disclosure Affects Property Taxes — and What to Do About It
Here’s a dimension of this issue most people don’t consider: because the Bexar County Appraisal District doesn’t have automatic access to sale prices, their assessed values can drift meaningfully out of step with actual market values. Sometimes BCAD over-assesses — and homeowners are quietly paying more in property taxes than they should be.
Texas law gives every homeowner the right to protest their appraisal with the Appraisal Review Board (ARB). The protest deadline in Bexar County is typically May 15th each year, though it can shift slightly. One of the most effective strategies for winning a protest is submitting recent comparable sales — which, again, requires MLS access or a skilled agent willing to pull that data for you.
I’ve helped clients in neighborhoods from Converse to Castle Hills gather the comp evidence they needed to successfully protest inflated assessments. It’s one of those underappreciated ways that having an active real estate relationship pays dividends long after the closing table. A garden doesn’t stop needing attention after planting day — and neither does homeownership.
How to Work With a Texas Agent to Get Real Pricing Data
If you’re thinking about buying or selling in the San Antonio metro — from the urban core near the Pearl and King William Historic District to the outer-ring suburbs of New Braunfels, Boerne, or Seguin — here’s the practical playbook. Ask your agent upfront to provide a full CMA with actual MLS sold comps, not just active listings or Zillow estimates.
A good CMA will show you the address, sale date, square footage, price per square foot, days on market, and list-to-sale price ratio for each comparable. If an agent hands you a single number without supporting data, push back. You deserve to understand the methodology, not just the conclusion.
Also ask about pending sales in your target area — homes that are under contract but haven’t yet closed. These don’t show final prices, but they tell you current demand and velocity. In a neighborhood like Timberwood Park or Fair Oaks Ranch where inventory moves quickly, pending activity is a real-time signal that closed sales data, by definition, can’t fully capture.
Texas Non-Disclosure State: Frequently Asked Questions
Can I find out what a specific house sold for in Texas without a realtor?
It’s genuinely difficult without MLS access. You can check Bexar County Appraisal District records at bcad.org to find assessed values and ownership transfer dates, but the actual sale price typically won’t appear. Some county deed records include a “consideration amount” line, but sellers in Texas commonly enter nominal figures like $10 rather than the real price, making this unreliable.
Occasionally, if a home was purchased with an assumable loan or through a specific financing instrument, fragments of price data appear in public filings — but this is the exception, not the rule. Your most reliable path is a licensed agent or an appraiser with MLS access who can pull confirmed sale data directly.
Does Texas non-disclosure law apply to new construction home sales too?
Yes — new construction sales in Texas are subject to the same non-disclosure rules as resale homes, which surprises many buyers shopping master-planned communities like Stillwater Ranch, Veramendi, or the newer phases of Alamo Ranch. Builders often post base prices publicly, but the actual closing price — after upgrades, incentives, lot premiums, and rate buydowns — is not required to be disclosed publicly.
This is significant because builder incentive packages can vary widely by phase, season, and buyer negotiation, meaning the “starting from” price on a sign can be quite different from the reality of what neighbors actually paid. Agents who work heavily with new construction can often share intel on recent closing patterns from their MLS data and builder relationships.
How does the Texas non-disclosure law affect home appraisals and mortgage approvals?
Licensed appraisers in Texas have access to MLS sales data through their own professional systems, so the appraisal process itself isn’t crippled by non-disclosure — appraisers can still identify legitimate comparables. The challenge arises when appraisers are working in very rural or low-sales-volume areas outside San Antonio, like parts of Medina or Atascosa counties, where the MLS comp pool is thin and they must stretch geographic or time parameters.
For conventional, FHA, and VA loans, appraisers are required to use actual arm’s-length sales transactions — not assessed values or Zestimates — so the quality of available MLS data directly affects their ability to support a contract price. Buyers in transitional neighborhoods where sales are infrequent should discuss appraisal risk with their agent before writing an offer at an aggressive price point.
Why do some Texas home sale prices appear on Zillow but others don’t?
When they appear, it’s usually because an agent voluntarily entered the sold price into the MLS and that data was syndicated to Zillow — not because of any legal requirement. Some brokerages and agents do input sold prices consistently, which is why you’ll occasionally see real figures on Zillow for certain properties.
However, coverage is uneven across the state and even across different San Antonio zip codes, depending on which brokerages and individual agents are diligent about updating closed records. Off-market sales, for-sale-by-owner transactions, and builder-direct sales are especially likely to have no price data on Zillow at all. Treat any Zillow sold price in Texas as a data point worth noting — but not a verified fact without MLS confirmation.
Is there any movement to change Texas’s non-disclosure law?
There has been periodic discussion at the Texas Legislature about moving toward disclosure, particularly as advocates argue it would improve market transparency and help homeowners protest unfair tax assessments more effectively. As of early 2026, Texas remains a non-disclosure state, and the real estate industry — which benefits from the information advantage that MLS access provides — has historically been a significant voice in those conversations.
Consumer advocates and some county appraisal districts have pushed for change, arguing that better sale price data would lead to fairer property tax assessments statewide. For now, the practical reality for San Antonio buyers and sellers hasn’t changed: MLS access through a licensed agent remains the gold standard for reliable sold price data, and that’s unlikely to shift in the near term without meaningful legislative action.
