Dallam County Commercial Property Tax Protest

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

A livestock feed and supply operator in Dallam County was surprised when their 2026 Notice of Appraised Value arrived showing a 16% increase on a property that hadn’t changed materially in five years. Located in Dalhart, the county seat, the property is a 6,500-square-foot retail/warehouse hybrid that sells livestock feed, supplements, and agricultural supplies. The surrounding neighborhood is primarily commercial — feed stores, farm supply operations, and service businesses serving the county’s agricultural community.

The operator had owned the property for a decade and knew the market. There hadn’t been a flood of new competitors. The agricultural economy in the Texas Panhandle had been relatively stable. Nothing had occurred to justify a 16% increase. So what happened?

The answer lay in the Dallam County Appraisal District’s cost-approach model. The district had updated its construction cost indices based on statewide data reflecting post-pandemic construction inflation — and those indices did show real increases in construction costs. But construction cost and market value are different things. The cost to build a new agricultural supply building in Dalhart had indeed increased. But would anyone pay that replacement cost for this existing 1995 building in a Panhandle county of 7,200 people? No. The market simply wouldn’t support it.

The operator filed a Notice of Protest before May 15, checked both market value and unequal appraisal grounds, and compiled an evidence package consisting of:

Income analysis: The store’s actual rental equivalent (as an owner-occupied property, the operator estimated a market rent based on comparable leases in Dalhart), operating expenses, and a capitalized value using a cap rate appropriate for a single-tenant rural commercial property. The capitalized value came in at approximately 22% below the assessed value.

Cost approach with obsolescence: A basic replacement cost calculation using RS Means regional data for the Texas Panhandle, then applied an economic obsolescence adjustment reflecting the limited buyer demand for this property type in a county with a population of 7,200. The economic obsolescence adjustment, grounded in population data and comparable rural Panhandle county commercial sales, reduced the value by approximately 28% from replacement cost — landing near the income approach conclusion.

Equity comparables: A review of comparable agricultural supply and service commercial properties in the Dallam County roll showed that several similar buildings were assessed at per-square-foot values 15% to 22% lower than the subject property. This equity comparison provided a second, independent basis for reduction.

At the informal hearing, the Dallam County Appraisal District appraiser reviewed the income analysis and acknowledged that the district’s construction cost update had not included a corresponding economic obsolescence review. The district offered a reduction of approximately 18% — nearly to the income approach value. The operator accepted.

Annual tax savings: approximately $1,350 at Dallam County’s combined rate. Contingency fee: $405 (30% of $1,350). Net savings to the operator in year one: $945 — and the full $1,350 benefit in every subsequent year until the next reassessment.

What Makes Dallam County Properties Vulnerable to Overassessment

Geographic isolation. Dallam County is in the extreme northwest corner of Texas — the Texas “panhandle’s panhandle.” It borders New Mexico to the west and Oklahoma to the north, with Sherman County (Stratford) as the only neighboring Texas county in two directions. This isolation significantly limits the commercial buyer pool: investors who purchase commercial real estate in rural Texas typically don’t target the most isolated Panhandle counties.

Small population, limited commercial demand. Approximately 7,200 residents means a very thin commercial demand base. A retail commercial property can only generate so much income when the market it serves has this size. The income caps translate directly to value caps that mass appraisal models often fail to recognize.

Agricultural economy cyclicality. Dallam County’s economy centers on agriculture — grain, cattle, and some oil and gas production. When commodity prices are down or drought affects farm income, commercial businesses serving the agricultural community experience reduced revenue. Income approach models should reflect this cyclicality, not just average or stabilized income.

Construction cost versus market value gap. As described in the case study above, the post-pandemic construction cost inflation shows up in cost approach models but doesn’t translate to equivalent market value increases in thin, rural markets. The gap between replacement cost and market value is largest in the most isolated, lowest-demand markets in Texas.

Commercial Property Types in Dallam County

Agricultural Supply and Services: Feed stores, farm supply, implement dealers, veterinary supply — the backbone of Dallam County’s commercial sector. See the case study above for the typical protest approach.

Feedlot and Livestock Support: Dallam County is part of the Texas Panhandle feedlot industry. Commercial properties supporting feedlot operations — trucking terminals, processing support, veterinary services — have highly specialized utility and limited buyer pools.

Retail and Food Service: Dalhart’s retail and food service businesses serve local residents and highway travelers on US 87/US 54. National brand presence is limited, and local retailers face competition from Amarillo (2 hours) and Clayton, New Mexico.

Energy Support: Some oil and gas production in and near Dallam County creates a limited energy services commercial sector.
