In Texas litigation, a property owner may be able to give an opinion about the market value of the owner's own property without first qualifying as a traditional valuation expert. But the Property Owner Rule is not a shortcut around evidence: the opinion still needs a factual, market-based foundation.
The Texas Property Owner Rule allows an owner who is personally familiar with the property and its market value to offer opinion testimony about the value of that owner's own property. The rule operates within Texas Rule of Evidence 701. It can eliminate the need to qualify the owner as a traditional valuation expert, but the owner still must explain the factual basis for the valuation; a bare or speculative number is not enough.
A property owner who remains dissatisfied after an Appraisal Review Board proceeding may decide to pursue a judicial appeal when the statutory requirements are met. Litigation can involve evidence, discovery, motion practice, and trial preparation. One practical question is how the owner will establish the property's value in admissible form.
The Property Owner Rule can matter because Texas law recognizes a special basis for an owner to testify about the value of the owner's own property. In an appropriate case, that can reduce reliance on a separately retained valuation expert. It does not mean an outside appraiser is never useful or that owner testimony will always be sufficient.

This example is for illustration only. Actual tax savings depend on taxable value, applicable tax rates, exemptions or limitations, the tax year at issue, litigation result, and other facts. The Property Owner Rule may affect evidence strategy, but it does not guarantee a reduction or eliminate litigation costs.
Texas Supreme Court decisions treat the Property Owner Rule as part of Rule 701. The rule is based on a presumption that an owner is familiar with the owner's property and its value, but the valuation opinion must still concern market value rather than personal, intrinsic, or speculative value.
In Natural Gas Pipeline Co. of America v. Justiss, the Texas Supreme Court emphasized that qualification as the property owner is not enough by itself. The owner must give the factual basis supporting the valuation. A number stated without explanation can be legally insufficient even if no one objects to the testimony.
Core rule: ownership can establish a basis to give the opinion, but the evidence still has to explain why the property is worth the amount claimed.
Justiss identifies several types of information that may provide the factual foundation for an owner's market-value opinion. The usefulness of any particular item depends on the property, valuation date, and issue being litigated.
| Potential Support | How It May Help |
|---|---|
| Price paid for the property | May provide market evidence when the transaction is relevant to the valuation date and circumstances. |
| Nearby comparable sales | Can help connect the owner's opinion to actual market activity involving similar property. |
| Tax valuations | May provide additional valuation history or context, depending on the issue and time period. |
| Appraisals | May provide a factual source for the owner's opinion, although the appraisal itself can raise separate evidentiary issues. |
| Online market resources | Can be part of the factual foundation when relevant and reliably tied to the market-value opinion. |
| Other relevant market factors | Property condition, income information, location, use restrictions, and other facts may matter depending on the case. |
The critical point is not simply to identify a source. The owner should be able to explain how the source supports the market-value number being offered.
Justiss states that, like expert valuation testimony, property-owner valuation testimony may be based on hearsay. But that does not mean every underlying document automatically becomes admissible evidence. The owner's opinion and the admissibility of a report, appraisal, statement, or other document are separate evidentiary questions.
The safer way to describe the rule is that hearsay can be part of the information on which an owner forms a valuation opinion, while the opinion itself must still be grounded in market value and supported by a factual explanation.
Avoid this mistake: an owner cannot simply repeat a number from an old appraisal or website and expect that number, standing alone, to establish market value. The owner should explain why the information is relevant and how it supports the valuation being offered.
It can, but the identity of the witness matters. In Reid Road Municipal Utility District No. 2 v. Speedy Stop Food Stores, Ltd., the Texas Supreme Court held that an organization can use the Property Owner Rule through an officer in a managerial position whose duties relate to the property, or an employee in a substantially equivalent position.
The witness must also be personally familiar with the property and its fair market value. Merely being associated with a related company, partnership, or ownership structure is not automatically enough.
This point is especially important for commercial real estate held through LLCs, limited partnerships, or other entities. The correct witness should be evaluated before relying on owner testimony as the valuation evidence.
The Property Owner Rule should not be read as a rule against appraisal experts. An outside appraiser may still be strategically useful where the valuation is complex, the property is highly specialized, the owner lacks a strong factual foundation, multiple appraisal methods are disputed, or an independent valuation will materially strengthen the case.
In other cases, well-prepared owner testimony may reduce the need for separate expert valuation testimony. The right approach depends on the property, the evidence, the amount in dispute, the litigation strategy, and procedural requirements.
It is a Texas evidence rule recognized in case law that allows a qualifying owner to give opinion testimony about the market value of the owner's own property without first establishing the same valuation qualifications that would ordinarily be required for a non-owner witness.
Potentially. A qualifying owner may give a market-value opinion under the Property Owner Rule, but the opinion still needs a factual basis. Whether an outside appraiser is necessary or strategically useful depends on the case.
No. The Texas Supreme Court has explained that a bare or speculative valuation is not enough. The owner should identify the factual and market-based information supporting the opinion.
Relevant support may include the price paid, nearby sales, tax valuations, appraisals, online market resources, and other market-based facts. The owner should explain how those facts support the value claimed.
Texas Supreme Court precedent states that owner valuation testimony may be based on hearsay, but that does not automatically make the underlying hearsay document admissible. The valuation opinion still needs a factual, market-based foundation.
Yes in appropriate circumstances, but the witness must fit the requirements identified by the Texas Supreme Court for entity-owned property and must be personally familiar with the property and its fair market value.
No. The rule concerns who may offer valuation opinion testimony and what foundation that testimony needs. It does not determine the ultimate value, eliminate opposing evidence, or guarantee a particular litigation result.
