This page explains exactly how we analyze your property. We evaluate whether the appraisal district’s market value materially deviates from actual market behavior.

1. Primary Data Sources

We rely on:

• Primary Residential Sales Database (licensed market data provider)
• County Appraisal District (CAD) record – official property characteristics and assessed value

We do not rely on automated valuation websites such as Zillow or Redfin. They are not accurate.

2. Comparable Sales Pool

We build a comparable sales set using our primary residential sales database.

Typical filters include:

• Same subdivision or directly competing subdivisions
• Similar living area range
• Similar year-built range
• Similar quality classification
• Detached single-family only
• Arms-length closed sales
• Minimum comparable sales count: 3

If fewer than 3 reliable sales exist, the matter may be categorized as Weak Data.
