Five property-value numbers that answer different questions
A Texas appraisal record may show market value, appraised value, taxable value, land value, and improvement value. They are related, but they are not interchangeable.

Market value is the district's January 1 estimate
Texas law generally requires taxable property to be appraised at market value as of January 1. The Texas Comptroller describes market value as the price a property would transfer for under prevailing market conditions when knowledgeable parties act without unusual pressure. That date matters. A later renovation, storm, sale, or market shift may not describe the property as it existed on January 1.
Appraisal districts value large groups of properties through mass appraisal. They classify properties, define market areas, analyze characteristics, calibrate models, and review results. This differs from a lender's appraisal of one property for one transaction. A district value is therefore an administrative estimate developed consistently across many accounts, not a promise that a particular buyer will pay that amount.
Market value is a dated appraisal conclusion. A sale price is the result of one transaction with its own condition, timing, financing, and negotiation.
Appraised value can be lower than market value
On many records, market value and appraised value are identical. They can separate when a legal limitation applies. A common example is a residence homestead appraisal cap. HCAD explains that a qualified homestead's appraised value is generally the lesser of its market value or its capped value. The market value itself is not capped; the limitation applies to the appraised value used in the tax process.
This produces a result that can surprise owners: the district may reduce market value without changing appraised value if the revised market value remains above the capped amount. It can also show market value increasing faster than appraised value. When comparing homes, decide which number addresses the question. Ammax Home uses published market appraisal value for market PSF because capped appraised values can reflect owner-specific history rather than only the property's current classification and characteristics.
Taxable value comes after exemptions and limitations
Taxable value is used by a particular taxing unit after applicable exemptions and limitations. One property can have different taxable values for a school district, county, city, or special district because exemptions and rules differ. Multiplying the headline market value by a tax rate will therefore not always reproduce the tax bill.
Ammax Home does not use taxable value to rank comparable homes. Taxable value can depend on exemptions and ownership circumstances that do not make two buildings physically more or less similar.
Land and improvement values divide the total
Land value represents the district's value allocation to the site. Improvement value generally represents buildings and other taxable improvements attached to the land. For many residential records, the relationship is straightforward:
The split is useful because location and lot utility can drive land value while construction quality, size, age, and depreciation affect improvement value. HCAD's published cost-approach explanation says its residential valuation program estimates replacement cost, applies adjustments for characteristics and depreciation, and then adds land value. The exact method and field availability can differ by district and property class.
An improvement value is not a contractor's bid, insurance replacement cost, or guaranteed contributory value. It is a component of the district's appraisal model. Likewise, land value is not necessarily the price a vacant version of the lot would command without considering demolition, assemblage, easements, or other site-specific issues.
Why two neighboring records can look inconsistent
Differences can reflect lot size, corner influence, flood exposure, neighborhood modeling, building class, effective area, quality grade, condition, depreciation, extra features, exemptions, or record timing. They can also reflect an error or an update that has not yet appeared online. A difference is a reason to investigate, not proof that one record is wrong.
Start by confirming the tax year and account identity. Then compare land and improvement components separately, read building details, and check whether market value or appraised value is being discussed. If a field is missing, do not silently replace it with zero.
