Introduction to Parcel Value Analysis

Parcel Value Analysis can be used to visualize key property characteristics on a map, discover neighborhood patterns, analyze sales ratios, and identify outliers and inequities.

Local assessors have a statutory responsibility to discover, list, and value property at current market conditions. These values are used to determine how much an owner must pay in property taxes to a local government. While property values are typically quite stable, turbulent housing markets can cause values to rise, or fall, dramatically. These dramatic changes in property value cause owners to question their property assessments and subsequent tax bills. Historically, the assessor’s computer aided mass appraisal (CAMA) system has been the primary source of property assessment information in a local government. However, these tabular systems make it difficult to visualize outliers and spatial patterns, assess the impact of geographic features on values, and identify trends. To ensure property is valued in a fair and equitable way, assessors need a simple way to visualize property characteristics and locate outliers that increase the likelihood of assessment appeals and reappraisals.

The Parcel Value Analysis solution delivers a set of capabilities that enable local governments to visualize key property characteristics on a map, discover neighborhood patterns, analyze sales ratios, and identify outliers and inequities.
