Culberson County Commercial Property Tax Protest

A Commercial Property Owner’s Journey Through the Culberson County Protest Process

A ranch supply and fuel stop operator in Culberson County received their 2026 Notice of Appraised Value from the Culberson County Appraisal District and found the assessed value had increased 18% from the prior year. On a combined tax rate of approximately 1.9%, that increase translated to roughly $1,800 in additional annual taxes — on top of an already substantial bill for a property in one of the least commercially active counties in the state.

The operator’s first reaction was skepticism: with only about 2,200 residents spread across 3,800 square miles of Far West Texas, who was supposed to be driving up commercial real estate values in Van Horn? The answer, it turned out, had nothing to do with genuine market demand.

The Culberson County Appraisal District had updated its cost-approach replacement cost estimates using statewide construction cost indices — indices calibrated for major Texas metro areas where construction materials are plentiful and labor is readily available. In Far West Texas, construction actually costs more per square foot than in most urban areas, because materials must be trucked significant distances and skilled tradespeople are scarce. But the market value of the completed structure — what a buyer would actually pay — is far less than replacement cost, because the economic base in Van Horn cannot support cost-approach values. The gap between construction cost and market value in remote Far West Texas is one of the largest in the state.

This is the classic economic obsolescence problem that drives commercial property overassessment in counties like Culberson. And it is exactly the kind of argument that wins property tax protests.

What Happened When the Operator Protested

The operator filed a Notice of Protest before the May 15 deadline, checking both market value overstatement and unequal appraisal grounds. With help from a consultant who understood the Far West Texas commercial market, the protest package included:

Actual income documentation: The fuel stop and supply operation’s revenue data for 2024 and 2025, showing that the business generated net operating income that, when capitalized at a realistic cap rate for an isolated Far West Texas highway operation, produced a value approximately 28% below the assessed value.

Replacement cost versus market value analysis: A cost approach showing the replacement cost new of the improvements, followed by a detailed economic obsolescence adjustment reflecting the significant gap between what it would cost to build the improvements and what an investor would pay for the property given the limited commercial demand in Culberson County.

Comparable isolated highway properties: Sales data from similar isolated highway commercial properties in Far West Texas — Hudspeth County to the north, Reeves County to the east, Jeff Davis County to the southeast — showing per-square-foot values consistent with the lower protested value and inconsistent with the assessed value.

At the informal hearing, the Culberson County Appraisal District initially defended its value. But faced with the income documentation showing the property simply could not support the assessed value based on its actual income, the district’s appraiser agreed to reduce the assessed value by approximately 19% — capturing most of the increase and restoring the assessment to near its prior-year level.

The annual tax savings: approximately $1,600. The contingency fee on those savings: significantly less than the savings themselves. Net result: the operator pays less, year after year.

Culberson County’s Commercial Market Context

Culberson County is defined by its geography — one of the largest counties in Texas by land area, with Van Horn (population approximately 1,800) as the only significant community. Interstate 10 passes through Van Horn and creates the primary commercial activity corridor. The county’s economic base includes:

Interstate highway commerce: Fuel stops, restaurants, motels, and convenience operations along I-10 serve long-haul truckers and travelers. These properties depend entirely on highway traffic and have no alternative commercial demand base.

Mining and extraction support: Culberson County contains potash deposits and other mineral resources that have historically supported some industrial and commercial activity. Mining support services — equipment yards, maintenance facilities, supply operations — value based on the cyclical nature of extraction activity.

Ranching support: The county’s vast ranch acreage requires some commercial support — veterinary services, feed and supply, light maintenance. These operations are small and have limited market value relative to replacement cost.

Solar energy facilities: In recent years, large-scale solar energy projects have been developed in Culberson and surrounding Far West Texas counties, attracted by the combination of land availability and solar irradiance. These facilities are primarily valued as personal property, but associated commercial and industrial real estate may appear on the county roll.

Tax Rates in Culberson County

Taxing Entity	Approximate Rate Range
Culberson County	0.48% – 0.65%
Culberson County ISD	0.80% – 1.08%
City of Van Horn	0.38% – 0.52%
Hospital District	0.10% – 0.18%

Combined rates for Van Horn commercial properties typically fall between 1.7% and 2.3%. Properties outside Van Horn city limits in unincorporated areas see lower combined rates of approximately 1.3% to 1.8%.

At a 2.0% combined rate, a $300,000 assessed commercial building generates a $6,000 annual tax bill. The economic obsolescence adjustment that brings a $380,000 replacement cost property down to $300,000 market value would save $1,600 per year at that rate — meaningful for a business serving a county of 2,200 people.

Five Specific Protest Strategies for Culberson County

1. Document the gap between replacement cost and market value. This is the central argument for most Culberson County commercial protests. Get local contractor estimates if possible, or use RS Means construction cost data adjusted for the Van Horn area. Then establish market value through income analysis or comparable sales, and document the difference.

2. Use income approach for highway commercial properties. Fuel stops, motels, and restaurants along I-10 generate income that can be directly analyzed. Actual revenue minus actual expenses, capitalized at an appropriate rate for an isolated Far West Texas highway location, is the most compelling evidence the district will see.

3. Challenge statewide construction cost indices. If the Culberson County Appraisal District used statewide or regional construction cost multipliers without adjusting for the specific cost premium of building in remote Far West Texas, point that out. The district may actually have used a higher-than-average multiplier — which, paradoxically, still doesn’t capture what buyers are willing to pay.

4. Research comparable sales in neighboring Far West Texas counties. The commercial property market in Hudspeth, Reeves, Jeff Davis, and Presidio counties shares many characteristics with Culberson. Sales data from these counties, when properly adjusted, can support lower market value conclusions for Culberson County properties.

5. Equity analysis from the Culberson County roll. With a small county roll and limited commercial properties, pull every commercial property’s assessed value per square foot and compare it to yours. Equity arguments can be very effective in small counties where individual property differences are more visible to ARB members.
