What "Market Value" Means in Texas

The statutory definition

Texas Tax Code § 23.01 requires appraisal districts to appraise taxable property at market value as of January 1, with exceptions (for example, productivity valuation for agricultural and timber land). Market value is the price at which a property would transfer for cash or its equivalent under prevailing market conditions if:

What the definition rules out

The definition is hypothetical but specific. It describes an arm's-length sale: a willing seller with reasonable exposure time, a willing buyer, full knowledge, and no pressure on either side. A forced sale, a sale between relatives, or a distressed transaction does not fit the definition neatly. Conversely, conditions only your household cares about — what you paid for improvements you enjoy, your personal financial situation — are not part of the definition either. The ARB is instructed that it cannot take your personal economic situation into account.

Why this matters when reviewing your assessment

When you gather evidence — a recent sale, comparable properties, condition documentation — its relevance flows through this definition. Evidence of what a willing buyer and seller would agree to, under open-market conditions, speaks to market value. Evidence of personal circumstances does not.

Worked example: testing a comparable against the definition (illustrative)

Illustrative scenario with made-up numbers — not a valuation, not your property, and not a prediction of what the ARB will decide.

  1. Scenario: your appraised value is $520,000. You find a sale at $455,000 in your neighborhood from eleven months ago.
  2. Step — check the sale against the definition: was it an arm's-length sale on the open market (not a relative-to- relative transfer, not a foreclosure, not a lease-option)? A distressed sale does not evidence the hypothetical transaction § 23.01 describes.
  3. Step — check recency and comparability: the statute's comparable-sale method expects sales within the lookback window and adjustments for differences in location, size, age, condition, access, and amenities. The sale is 11 months old — within the window. The comparable has 200 fewer square feet and no garage; you note both and adjust rather than ignore them.
  4. Step — state the conclusion: "An arm's-length sale 11 months old, adjusted upward for the missing garage, supports a market value near $470,000, not $520,000."

What this tells you: the definition is the test your evidence has to pass. A comparable that fails one element — a non-arm's-length sale, a sale outside the recency window, a property that differs in ways you cannot adjust for — weakens rather than supports your case, so it is better to filter your evidence through the definition before you file.

What it does not tell you: what the district's own comparables show, how the ARB will weigh your adjustments, or whether a different method (income or cost) fits your property type better.
